Canon has introduced the PowerShot SD4000 IS Digital ELPH, also known as the IXUS 300 HS in Europe, as its latest addition to the compact camera lineup. Marketed as a low-light performance specialist with a sleek design and ease of use, the Canon SD4000 has sparked interest among casual users and photographers alike. While its predecessor, the Canon S90, received acclaim for its image quality and manual controls, the SD4000 aims to attract a wider audience through its speed, video capabilities, and affordability. The question remains whether the SD4000 is a true innovation or simply a marketing effort to fill a product gap in Canon’s compact camera line.
Design and Build Quality
The Canon SD4000 IS boasts a clean, stylish appearance with a slim, pocketable body that maintains a solid feel in hand. Its brushed metal finish gives it an elegant look, available in various color options like red, black, and silver. Despite its compact form, it features a bright f/2.0 aperture lens, a relatively rare find in point-and-shoot cameras. The lens allows for more light to reach the sensor in darker environments, making it ideal for indoor and evening photography. However, one noticeable limitation is the 230,000-pixel resolution of its LCD screen, which appears significantly lower in clarity compared to competitors like the Canon S90 with its 461,000-pixel display. This drawback becomes apparent when reviewing images or navigating menus in bright outdoor conditions.
Performance and Core Features
The Canon SD4000 IS is built around a high-speed back-illuminated CMOS sensor that Canon claims to offer improved low-light performance. Its 1/2.3-inch sensor (6.16x4.62mm) is smaller than that of the Canon S90, but the new design promises enhanced sensitivity and noise handling. The SD4000 also supports 720p HD video recording, which is an improvement over the Canon S90, which lacks HD capability. With a burst rate of 8 frames per second, the SD4000 is exceptionally fast for a compact camera, making it suitable for capturing fast-moving subjects or spontaneous moments. Additionally, it includes a slow-motion video feature that allows users to record action sequences with dramatic visual effects, further enhancing its appeal to casual videographers.
Aperture and shutter priority controls (Av, Tv modes) are available, though full manual controls are missing. Unlike the S90, there is no RAW shooting support, no customizable control ring, and no manual exposure option. This makes the SD4000 less suitable for photographers who prefer more creative control or who engage in post-processing workflows. Instead, it targets users who prioritize convenience and automatic settings over manual adjustments.
Underwater Photography Potential
For underwater photography enthusiasts, the Canon SD4000 presents a mixed bag. On one hand, it lacks many features valued by experienced underwater photographers, such as RAW format, full manual settings, and advanced white balance control. On the other hand, it benefits from its compact size and high-speed shooting capabilities. The camera’s fast burst mode can help capture fast-moving marine life, and the f/2.0 lens may perform well in shallower, low-light underwater settings.
A notable highlight is the availability of an underwater housing from Ikelite, a trusted name in underwater gear. This housing is compact and well-matched to the SD4000’s dimensions, allowing for a seamless underwater experience. However, due to the absence of manual exposure and RAW, users may face limitations when attempting to capture complex lighting conditions beneath the surface.
When comparing it to the Canon S90, the SD4000 falls short in many of the essential areas that matter to underwater photographers. The S90 offers better overall image quality, full manual controls, and RAW output, which are vital for managing difficult underwater lighting scenarios and editing photos post-dive. Unless HD video is a top priority, the SD4000 is not a clear winner in the underwater photography domain.
Summary Verdict
Despite its streamlined design, quick performance, and decent low-light capability, the Canon SD4000 IS does not surpass the Canon S90 in terms of photographic versatility or image quality. It is designed more for casual users who want a stylish, high-speed camera that performs reasonably well in various everyday scenarios. The SD4000's omission of RAW, full manual modes, and a high-resolution LCD limits its appeal among advanced users and underwater photographers.
The addition of HD video and a faster burst rate provides some value, especially for those focused on capturing action or short clips. Still, it’s difficult to overlook what has been lost compared to the S90. With the S90 available at a similar price point and offering far more control for serious shooters, it remains the better choice for those prioritizing photography quality and flexibility.
Canon's SD4000 IS may find a place among those looking for a hassle-free compact camera with decent features and speed. But for anyone seeking greater control, flexibility, or underwater shooting prowess, it’s a compromise that may not justify the cost.
Image Quality and Sensor Analysis
The Canon SD4000 IS uses a high-speed back-illuminated CMOS sensor, which is designed to perform better in low-light situations than traditional front-illuminated sensors. The back-illumination allows more light to hit the photodiodes directly by moving the wiring to the rear of the sensor, which increases sensitivity and reduces noise. This technology is especially useful for indoor or nighttime photography, where light is limited. While the sensor is smaller than that of the Canon S90, which uses a larger 1/1.7" CCD sensor, the SD4000 aims to make up for this through improved design and high-speed image capture.
In practice, image quality from the SD4000 is good but not exceptional. In well-lit environments, the camera produces clean images with accurate colors and decent dynamic range. The automatic white balance performs reliably in most daylight conditions, though it sometimes struggles with mixed or artificial lighting. Sharpness is generally good in the center of the frame, but it softens slightly toward the corners, especially when shooting wide open at f/2.0. This is expected in most compact cameras with fast lenses and small sensors.
Noise handling is acceptable up to ISO 800, with ISO 1600 being usable for small prints or web use. Above ISO 1600, image degradation becomes more apparent. Fine detail is lost due to aggressive noise reduction, and color fidelity begins to suffer. In comparison to the Canon S90, which handles higher ISO settings with more grace due to its larger sensor, the SD4000 falls slightly behind in retaining fine detail and color depth. However, for most casual users who do not pixel-peep or print large photos, the performance will be more than sufficient.
Lens Performance and Optical Characteristics
One of the standout features of the Canon SD4000 IS is its fast f/2.0 aperture lens, especially at the wide end of its 28-105mm equivalent zoom range. The wide aperture allows for better performance in dim lighting and can create a shallower depth of field effect, although the small sensor limits the extent of background blur. This is beneficial for portraits, close-up shots, and other situations where background separation is desirable.
Lens sharpness is commendable at the center of the frame, especially at wider apertures. However, the edges and corners can show some softness, which is typical of compact zoom lenses. Chromatic aberration is present but well-controlled, with minimal purple fringing observed in high-contrast scenes. Distortion is modest and corrected well by in-camera processing.
The 28mm wide-angle focal length is suitable for landscapes and group shots, while the 105mm telephoto end helps capture distant subjects or tighter portraits. Optical image stabilization works effectively to reduce blur from hand shake, particularly in low-light conditions or when shooting at longer focal lengths.
Overall, the lens is one of the SD4000’s strengths. It combines speed, versatility, and optical stabilization in a compact form. While it does not offer the same level of control or customizability as a camera with interchangeable lenses, it performs reliably across a range of everyday shooting scenarios.
Video Capabilities and Slow-Motion Mode
Unlike the Canon S90, the SD4000 introduces HD video recording, allowing users to capture 720p high-definition video at 30 frames per second. The video quality is decent, with smooth motion, clear audio, and acceptable detail. Focus during video recording is fixed at the beginning of the shot, which can limit usability for dynamic scenes. Autofocus noise is not recorded, and the built-in microphone picks up ambient sound reasonably well for casual use. There is no external microphone input, which restricts the camera’s use for professional video applications.
An interesting addition to the SD4000 is its slow-motion video feature, which records at very high frame rates and plays back in slow motion. This mode is fun for capturing fast-moving subjects, such as splashing water, sports action, or animals in motion. However, the resolution is significantly lower in this mode, and image quality is visibly reduced. Even so, it adds creative potential for users who want to experiment with different video effects.
While video controls are limited, and there is no manual exposure adjustment during recording, the SD4000’s video performance is perfectly suitable for family events, travel, and casual filming. The inclusion of HD video and slow motion gives it a multimedia edge over the S90, even though the overall image quality and shooting flexibility remain geared toward beginner and mid-level users.
Ease of Use and User Interface
Canon designed the SD4000 to be user-friendly and accessible, catering to photographers who prioritize simplicity over control. The camera features a standard menu system with logically arranged options and icons. The buttons are responsive, though small, and may not be comfortable for users with larger fingers. The interface is typical of Canon’s compact lineup, intuitive enough for first-time users while offering modest customization for those who want more control.
Scene modes include Smart Auto, Portrait, Kids & Pets, Low Light, Beach, Foliage, and more. The Smart Auto mode does a good job of detecting the scene type and adjusting settings accordingly. In most cases, users can rely on auto mode without worrying about exposure or focus adjustments. For users looking to explore more advanced settings, the SD4000 offers Program mode along with Aperture (Av) and Shutter Priority (Tv), allowing for partial control over exposure. However, there is no full manual (M) mode, which may disappoint users who want to fine-tune every aspect of the image.
Navigation through settings is quick, and the camera starts up and responds swiftly. The burst shooting feature is also easy to access, and the transition between photo and video modes is seamless. The limited number of physical controls and the absence of a control ring, such as the one found on the Canon S90, result in a more straightforward but less flexible interface.
Battery Life and Storage
Battery life for the Canon SD4000 is average. It uses a rechargeable NB-6L lithium-ion battery, which is rated for approximately 250 shots per charge under standard shooting conditions. This number can vary depending on how often the LCD is used, whether flash or video recording is enabled, and the frequency of image review. For typical day trips or casual outings, the battery should last sufficiently. However, for extended sessions or travel, carrying a spare battery is recommended.
The camera accepts SD, SDHC, and SDXC memory cards, providing ample storage options. The inclusion of HD video and high-speed burst shooting means that users will benefit from faster cards to prevent lag during recording or continuous shooting. File sizes remain manageable due to the absence of RAW format support, so most users will find even mid-range cards sufficient for regular usage.
Connectivity and Accessories
In terms of connectivity, the Canon SD4000 offers standard mini USB and AV output ports. There is no HDMI port for direct playback of HD video on televisions, which could be a downside for some users. Transferring files to a computer is simple via USB, and Canon’s bundled software allows basic editing and organization.
A range of accessories is available, including the Ikelite underwater housing. This makes the SD4000 a viable option for snorkeling and recreational diving, even though its limitations in manual control and RAW output restrict its use for advanced underwater photography. Optional wrist straps, cases, and screen protectors are also available to enhance portability and protection.
Although wireless features such as Wi-Fi, Bluetooth, or GPS are not built into the SD4000, this is expected given the camera’s release period and target market. These omissions would later be addressed in future Canon compact models aimed at connectivity and social sharing.
Competitor Comparison and Market Position
The Canon SD4000 was launched at a retail price of $349, positioning it in the mid-range segment of point-and-shoot cameras. At the time of its release, it competed directly with models such as the Panasonic Lumix ZS7, Sony Cyber-shot WX series, and Canon’s own S90. Among these, the SD4000 stands out for its speed, HD video, and compact size.
Compared to the Canon S90, the SD4000 sacrifices manual control and RAW format but gains HD video, a faster burst rate, and slow-motion capabilities. The S90’s larger sensor, higher-resolution screen, and control ring make it a better choice for serious photographers, especially those interested in post-processing or challenging lighting conditions. Meanwhile, the SD4000 is better suited for casual users who want quick, stylish results with minimal setup.
In today’s market, compact cameras face stiff competition from smartphones, which offer increasingly sophisticated imaging capabilities. However, the SD4000 still holds relevance for users seeking an optical zoom lens, better low-light performance, and a dedicated camera body that complements their smartphone.
Real-World Use and Practical Impressions
In practical use, the Canon SD4000 performs reliably in a variety of settings. It excels in daylight photography, street scenes, and casual portraits. The f/2.0 aperture proves valuable indoors and in low light, allowing the camera to maintain lower ISO levels and faster shutter speeds. Autofocus is generally fast and accurate, although it can struggle slightly in very dim lighting.
The camera’s high-speed burst mode is useful for capturing fleeting moments, such as children playing or pets in motion. Combined with its slim profile and lightweight construction, the SD4000 is easy to carry and quick to deploy. It becomes a natural choice for travel or day-to-day documentation without the bulk of larger systems.
Limitations emerge when users attempt to shoot in challenging conditions, such as scenes with extreme contrast or fast-moving subjects in low light. The lack of full manual control makes it difficult to override the camera’s exposure choices, and the absence of RAW restricts recovery options during editing. Even so, most casual photographers will appreciate it.
Underwater Photography with the Canon SD4000
Underwater photography demands specific qualities in a camera, including strong low-light performance, precise control over settings, and compatibility with underwater housings. The Canon SD4000 offers a mixed experience in this regard. While it is a compact and fast camera with a bright f/2.0 aperture and HD video, it lacks several features that advanced underwater photographers depend on. These include RAW image capture, full manual controls, and a control ring for easy access to settings. Despite this, its compact size and available underwater housing make it accessible for entry-level underwater enthusiasts.
The SD4000 is compatible with a dedicated underwater housing manufactured by Ikelite. This housing is built to be compact, lightweight, and durable, making it suitable for shallow diving and snorkeling. The physical buttons on the housing align well with the camera controls, allowing for basic operation beneath the surface. While it lacks more advanced housing accessories, such as ports for external strobes or lens filters, it provides a sufficient introduction to underwater imaging for users who are new to this form of photography.
The f/2.0 lens provides a welcome advantage underwater, where light is quickly lost with depth. At shallow depths or in clear water, the camera can perform decently without a flash, capturing ambient light in scenes with minimal motion. However, as depth increases, so does the need for additional lighting. Without RAW support, users are unable to fully correct the color cast of blue or green in post-processing. White balance adjustments are limited to presets, which may not be sufficient in challenging environments.
The SD4000’s fast burst mode and slow-motion video capabilities add creative value underwater. While the video resolution may be reduced in slow-motion mode, the ability to film marine life and observe their movements in detail is appealing to divers and snorkelers. However, the camera’s limited control over focus and exposure means that users may need to rely heavily on auto settings and experiment to get desirable results.
Differences Between the SD4000 and Canon S90 for Underwater Use
Comparing the SD4000 with the Canon S90 in the context of underwater photography highlights their distinct strengths and weaknesses. The S90 is widely considered one of the top compact cameras for underwater photography due to its larger sensor, RAW image support, full manual controls, and customizable control ring. These features allow divers to manage difficult lighting conditions and correct color balance and exposure with precision, especially when using external strobes.
The SD4000, by contrast, simplifies the underwater shooting experience but at the cost of flexibility and image quality. The absence of RAW means that color correction must be handled in-camera, where the options are more limited. Without manual mode, users cannot adjust shutter speed or aperture precisely to control motion blur and depth of field. The LCD resolution is also significantly lower than the S90, making it harder to judge focus and exposure in real time.
However, the SD4000 has its advantages. Its HD video feature allows users to capture footage of underwater scenes with a level of clarity and detail that the S90 cannot match. The 8 frames-per-second burst rate also enables capturing fast-moving subjects, such as fish or sea turtles, more effectively. For divers interested in video and fast action, the SD4000 may offer an enjoyable experience despite its limitations.
The decision between these two models ultimately depends on the user's priorities. If control, image quality, and post-processing flexibility are key, the S90 is the better choice. If compactness, speed, and HD video are more appealing, the SD4000 becomes a viable alternative for casual underwater exploration.
Evaluating the Camera for Travel and Lifestyle Photography
Outside of underwater use, the Canon SD4000 excels as a travel companion and lifestyle camera. Its sleek design and lightweight build make it easy to slip into a pocket or purse, ready to capture moments at a moment’s notice. The camera starts up quickly and responds well to sudden shooting opportunities, making it ideal for street photography, group outings, family events, and vacations.
Its performance in low-light environments stands out, particularly in restaurants, museums, or nighttime cityscapes. The f/2.0 aperture allows more light into the sensor, reducing the need for flash in dim conditions. This makes the camera less intrusive in social settings while still delivering reasonably sharp images. The CMOS sensor helps maintain image quality at higher ISO settings, though noise becomes noticeable beyond ISO 800.
For travelers interested in capturing both stills and video, the SD4000 provides a satisfying all-in-one solution. The HD video mode enables users to record scenes on the go, whether it’s a bustling marketplace, cultural performance, or natural landscape. The lack of advanced controls simplifies operation for those who prefer not to worry about settings, though more experienced photographers may find the limited options frustrating.
Battery life during travel is generally sufficient for a day of moderate use, especially if flash and video are used sparingly. However, for extended trips or days with heavy shooting, carrying an extra battery is a wise choice. The camera’s small size and lightweight charger make it easy to keep it powered during transit.
Strengths of the Canon SD4000 for the Average User
The Canon SD4000 shines most when used by its intended audience: everyday consumers looking for a simple, attractive camera that delivers solid results.

Limitations That May Affect Certain Users
Despite its many strengths, the Canon SD4000 is not without significant limitations that may deter more advanced users. First among these is the lack of RAW image capture. JPEG-only shooting limits the ability to make detailed corrections during editing. Exposure, white balance, and color fidelity adjustments are constrained by the compression and in-camera processing of JPEG files.
Second, the absence of full manual controls reduces the photographer’s ability to creatively influence exposure and composition. While Program, Aperture, and Shutter Priority modes provide some flexibility, the inability to lock ISO, shutter speed, and aperture simultaneously is restrictive for users with specific creative goals. Night photography, long exposure work, and manual strobe synchronization are largely off-limits.
Third, the camera’s LCD screen, with only 230,000 pixels, is below average even for its time. This affects image review and focus confirmation, particularly in bright outdoor settings. Users may struggle to assess their shots accurately and find themselves disappointed when viewing images on a larger screen.
Fourth, the fixed lens range of 28–105mm, while versatile for general use, lacks the reach needed for wildlife or sports photography. There is also no macro mode for extreme close-ups. Although the lens performs well within its range, the lack of lens customization or digital enhancements limits its adaptability to diverse shooting styles.
Finally, the SD4000 lacks modern features such as GPS, Wi-Fi, or Bluetooth, which are now common even in budget cameras and smartphones. This means geotagging, wireless file transfer, and remote control are unavailable. Users who prioritize connectivity or integration with mobile devices may find this a deal-breaker.

Long-Term Usability and Maintenance
Long-term usability is a major consideration when evaluating any digital camera, particularly a compact one that may see frequent use. The Canon SD4000 was designed to be a high-speed, easy-to-use companion for day-to-day shooting, but how does it hold up after extended usage?
The body construction is solid for a compact camera. The metal exterior withstands light drops and scratches reasonably well, especially if the camera is carried in a protective case. Buttons and dials retain their clickiness over time with regular care, and the lens mechanism remains smooth and responsive. The pop-up flash is rarely needed due to the wide aperture lens, but when used, it performs consistently for short-range scenes.
However, long-term battery performance tends to diminish after a year or two. The NB-6L lithium-ion battery may no longer hold a full charge, requiring users to purchase replacements. These are still available from third-party manufacturers, though genuine Canon batteries may become scarce as the model ages. The proprietary battery charger is also something to watch, as replacements may be more difficult to find compared to universal USB chargers used by newer models.
One of the benefits of older compact cameras like the SD4000 is their minimal reliance on software or connectivity. With no Wi-Fi, GPS, or Bluetooth, fewer components can fail or become outdated. However, the lack of firmware updates and long-term software support means that users are essentially locked into the camera’s original design with no future improvements.
SD, SDHC, and SDXC cards remain widely supported, which is helpful for continued usability. Most card readers, computers, and printers still accept these formats, so file transfer is straightforward. However, the camera uses a mini USB port rather than the now-standard micro USB or USB-C. This may require users to store or source the original cable type, as generic replacements may not fit securely.
Physically, the LCD screen is prone to scratches if not protected by a screen film. It may also dim slightly over time, though this has more to do with overall wear and tear rather than any design flaw. Optical image stabilization continues to perform well for general photography, though it may become less effective in extreme situations like shooting from moving vehicles or boats.
Ultimately, the SD4000 was built with consumer durability in mind. It is not ruggedized or weather-sealed, but when treated with care, it maintains functionality for years. This makes it a viable backup or secondary camera even long after its release.
Upgrading from the Canon SD4000: What to Consider
Users who started their photography journey with the Canon SD4000 may eventually look for an upgrade. When deciding what features matter most in a successor camera, it's helpful to consider what the SD4000 lacks and what newer models can offer.
A logical next step for most users would be a camera that includes RAW image capture, full manual controls, a higher-resolution screen, and better connectivity. In recent years, even entry-level compact cameras have introduced Wi-Fi for direct sharing, Bluetooth for remote shutter control, and built-in GPS for geotagging photos. These features align with modern expectations for instant sharing and location-aware photography.
Sensor size is another important consideration. Moving from the 1/2.3" sensor of the SD4000 to a larger 1" sensor or APS-C sensor brings a noticeable improvement in image quality, especially in low light. Cameras like the Canon G7X series or Sony RX100 series offer this step up while maintaining a compact body. These models also often include 4K video, touchscreens, and much better dynamic range.
Another major leap would be moving to a mirrorless interchangeable lens camera. These offer ultimate flexibility and creative control, though they also come with increased size, complexity, and cost. For users who enjoyed the simplicity of the SD4000 but want more power, bridge cameras or advanced compacts are a balanced alternative.
When upgrading, users should also consider lenses, accessories, and future needs. For underwater photographers, models compatible with dive housings and wide-angle wet lenses may be essential. For travel shooters, weight, zoom range, and battery life become key factors.
Ultimately, the right upgrade depends on what the user valued most in the SD4000. If ease of use and portability were the highlights, a newer, advanced compact may suffice. If the main frustration was a lack of manual control, an entry-level mirrorless camera would open up new creative possibilities.
How the Canon SD4000 Reflects Trends in Camera Evolution
