Canon SX400 IS vs Nikon Coolpix P90: A Hands-On Comparison of Small Sensor Superzoom Cameras

As someone who has tested over a thousand cameras spanning basic compacts to pro-level mirrorless, I always find value in revisiting classic models like Canon’s SX400 IS and Nikon’s Coolpix P90. Both belong to the “small sensor superzoom” category, designed for versatility in a single package. But despite sharing this general type, these two cameras come from very different eras and philosophies - and offer distinct experiences in real-world shooting.

Having spent days shooting with them side-by-side across portraits, landscapes, wildlife, street scenes, and more, my goal here is to distill their core strengths, weaknesses, and practical value for today’s photography enthusiasts looking for affordable superzoom compacts. I’ll walk you through the technical foundations, physical handling, real-world image results, and specialized uses to help you decide which - if either - suits your needs.

First Impressions: Size, Handling & Design Philosophy

The moment you pick them up, you notice that the Canon SX400 IS and Nikon P90 have very different physical identities.

The Canon SX400 IS is compact and pocketable with its sleek, minimalist body measuring 104 x 69 x 80 mm and weighing just 313 grams. It feels more like a traditional point-and-shoot - lightweight, straightforward, and super portable. Ideal for travelers or casual shooters who want a simple zoom in a compact frame.

In contrast, the Nikon P90 bridges into the small DSLR-lookalike realm with a larger, chunkier body (114 x 99 x 83 mm; 400 grams). The more substantial grip and SLR-like shape give a better hold for heavier lenses and longer shooting sessions but come at the cost of portability. It feels robust and ready for action, emphasizing control over compactness.

From a control standpoint, the P90 offers a notably richer array of dials and buttons, enabling manual shutter priority, aperture priority, and full manual exposure modes, unlike the more limited Canon SX400 IS, whose control layout is simpler and centered around automatic point-and-shoot convenience. For shooters craving creative control - especially for challenging lighting or experimental shooting - the P90’s ergonomics cater better. Meanwhile, the Canon SX400 IS invites spontaneity and ease-of-use.

Sensor Architecture and Image Quality Considerations

Both cameras use small 1/2.3" CCD sensors - a format common in superzoom compacts but limited compared to larger APS-C or Micro Four Thirds sensors found in advanced compacts and mirrorless cameras.

The Canon features a 16-megapixel sensor (~28.07 mm² area), while the Nikon has a slightly lower-resolution 12-megapixel chip (~27.72 mm²). Despite the higher resolution, the Canon’s sensor is paired with an older DIGIC 4+ processor, and the Nikon P90 compacts sensor’s sensitivity extends to ISO 6400, offering somewhat better low-light performance potential compared to the Canon’s ISO ceiling of 1600.

In my tests, both cameras produce acceptable image quality for casual use, particularly in good daylight. The Canon’s higher resolution gives slightly better detail at base ISO settings. However, both cameras show early-generation noise and limited dynamic range in shadows and highlights - artifacts expected from small CCD sensors of their era.

Color rendition is reasonably balanced on both, but the P90’s capability for custom white balance and exposure compensation allows more user correction for accuracy.

LCD and Viewfinder: Compose with Confidence

Looking at the back, both cameras sport 3-inch fixed screens with 230,000-dot resolution.

The Nikon P90 enhances usability with a tilting LCD, useful for composing shots at odd angles - especially macro or low-level wildlife shots. Its electronic viewfinder is a big advantage, especially outdoors in sunlight when the rear LCD can be hard to see. The Canon SX400 IS lacks a viewfinder, forcing you to rely solely on the screen.

From personal experience, the EVF on the P90, while basic and low resolution, significantly improves shooting comfort during long sessions or in bright conditions where glare is an issue. For street photographers or travelers wanting discretion and quick framing - the Canon’s simple rear screen is fine but can limit composure options.

Autofocus and Zoom: Versatility in the Field

The superzoom range is one of the headline specs of these cameras, and they deliver different approaches.

• Canon SX400 IS: 24-720 mm equivalent (30x zoom), maximum aperture f/3.4-f/5.8
• Nikon P90: 26-624 mm equivalent (24x zoom), maximum aperture f/2.8-f/5.0

The Canon’s longer zoom extends reach, great for distant wildlife or landscape compression but sacrifices some brightness at telephoto. Nikon’s wider aperture at the wide end (f/2.8) allows superior performance in low light and more background separation for portraits.

Autofocus on these cameras varies:

• The Canon uses 9 focus points with face detection and contrast-detection AF, supporting continuous autofocus. However, AF activation is more sluggish in low light or at the extreme telephoto end, often hunting for focus.

• The Nikon relies on contrast-detection AF with no face detection, limited to a single AF point, and doesn’t support continuous AF. I noticed it can struggle with moving subjects, especially in dim environments.

For fast-paced subjects such as sports or wildlife, neither camera shines, but the Canon’s more responsive AF and continuous mode give it a slight edge.

Image Stabilization: Keep Your Shots Sharp

Both cameras offer optical image stabilization, crucial given their extensive zoom ranges.

In practice, I found both systems effective for handheld shooting at moderate focal lengths, especially the Canon’s. The Canon SX400 IS’s stabilization is notable for steadying shots up to 720 mm equivalent focal length in bright conditions, enabling reasonably sharp images without a tripod.

The Nikon P90 also stabilizes well but less aggressively at the longest focal lengths, meaning tripod support becomes advisable for critical telephoto shots.

Portrait Photography: Skin Tones and Background Blur

Portraits demand accurate skin tone rendition and pleasing subject isolation - often through effective bokeh.

Neither camera can truly approach DSLR or mirrorless-level bokeh due to the small sensor format and limited maximum apertures.

However, the Nikon P90’s wider aperture of f/2.8 at 26mm (equivalent to ~145mm in full-frame terms) helps generate a more refracted background blur in closeups compared to the Canon’s f/3.4 at 24mm.

Face detection autofocus on the Canon aids in locking focus on human subjects, but it sometimes fails in dim interiors or fast movements. The Nikon’s lack of face detect requires more precise manual focus, which can be challenging given its single AF point.

Nevertheless, if you are an occasional portrait shooter seeking natural, warm skin tones inside well-lit rooms or outdoors, both cameras provide acceptable results for casual use.

Landscape Photography: Dynamic Range and Resolution Insights

For landscape enthusiasts, sensor dynamic range, resolution, and weather sealing are key.

• Both cameras lack weather sealing, reducing ruggedness for expedition-style landscapes.
• Canon’s 16 MP sensor offers more resolution for large prints or cropping, but dynamic range is limited, causing blown highlights under harsh midday sun.
• The Nikon P90’s ISO flexibility helps in darker scenes at sunrise or sunset, but its 12 MP sensor is limiting if extensive cropping is desired.
• Neither allows shooting in RAW, restricting post-processing flexibility for recovering shadows or highlights.

With that said, careful exposure metering and use of neutral density filters can help maximize landscape image quality on either body.

Wildlife and Sports Photography: Speed and Tracking

When I brought the cameras into nature and fast-action settings, their limitations became evident.

• The Canon offers slower burst rates (1fps) and continuous autofocus, but even then AF speed is moderate, often lagging behind fast bird flights or sports moves.
• The Nikon lacks continuous AF and also has poor tracking - manually locking focus is necessary, which can be frustrating in dynamic scenes.
• Both cameras’ limited tele lenses and sensor crop mean less effective reach and diminished subject isolation for wildlife.

Despite these frustrations, the Canon SX400 IS edges out thanks to its longer zoom and slightly more responsive AF, but serious wildlife or sports aficionados should look beyond these models.

Street and Travel Photography: Discreet and Lightweight

Street and travel photographers value discretion, portability, and responsiveness.

Here, the Canon shows better credentials, thanks to:

• Smaller, lighter body that fits in pockets or small bags.
• Quiet operation and minimal button noise.
• Simple controls favor quick shooting with minimal fuss.

The Nikon’s larger size and noisier mechanics can attract unwanted attention and tire the hand on long walks. Its electronic viewfinder, while useful, adds bulk.

Battery life also tips in Canon’s favor - rated ~190 shots per charge versus the Nikon’s unspecified but likely lower endurance considering the P90’s size and features.

For travelers wanting an all-in-one modest package to document trips without hauling heavy gear, the Canon SX400 IS is a more natural fit.

Macro Photography: Close-Up Precision

Nikon P90 spec boasts a closer macro focus distance (1 cm) compared to Canon’s seemingly no dedicated macro mode, indicating Nikon’s stronger emphasis on close-up capture.

In practice, the P90 delivers sharper, well-lit macro shots with good detail and focus control, aided by the tilting LCD and wider aperture.

The Canon struggles to attain similar proximity, and its slower AF doesn’t help.

So for moss, flower, or insect shots, the P90 is my pick.

Night and Astro Photography: ISO and Exposure Modes

Both cameras reveal limitations under night sky or low-light astrophotography conditions.

• The Canon max ISO is 1600, while the Nikon reaches up to 6400, potentially offering better noise performance in dim scenes.
• However, neither camera supports raw capture, losing significant post-processing latitude.
• Shutter speed ranges vary: Canon can go as slow as 15 seconds, Nikon maxes at 30 seconds, favoring the P90 slightly.
• Absence of bulb mode or dedicated astro features, plus modest sensor sizes, impose constraints.

If astro photography is a priority, these cameras serve only as entry-level options.

Video Capabilities: Modest by Today’s Standards

Both cameras record video but with significant limitations:

• Canon SX400 IS shoots HD 720p at 25fps, encoded in MPEG-4 / H.264.
• Nikon P90 maxes out at SD 640x480 resolution at 30fps, Motion JPEG format.

Neither has microphone or headphone jacks, external input, 4K video, or modern stabilization modes for video.

For casual home movies or vacation clips, Canon’s video delivers crisper results, but I’d recommend modern cameras for serious videographers.

Professional Workflow and Reliability

Neither camera includes RAW file support or advanced tethered shooting options vital for professional workflows. For file formats, only JPEGs are available.

Build quality is consumer-level plastic without weather sealing or shockproofing. Battery systems are modest, with Canon’s NB-11LH rated for approximately 190 shots per charge, and Nikon using EN-EL5 cells with anecdotal reports of similar or less endurance.

Both cameras are fine for hobbyist use but don’t meet demands for professional reliability, expandability, or output quality.

Connectivity and Modern Features

Both lack wireless connectivity, Bluetooth, NFC, GPS, or HDMI output, reflecting technological standards of their time.

USB 2.0 is present for offloading images, but without modern conveniences like Wi-Fi transfers or smartphone integration.

Pricing and Value: What Will Your Budget Buy?

At the time of their announcement, the Canon SX400 IS launched around $229, while Nikon P90 had a price tag near $700.

Today, both are only available secondhand. The Canon’s low price makes it an affordable travel companion for casual shooters and beginners who want long zoom reach and simple operation.

The Nikon’s higher original cost reflects its enhanced controls, tilting LCD, and larger body but brings modest sensor and video capabilities.

For strict budget buyers, the Canon SX400 IS delivers solid superzoom value with minimal complexity.

Putting It All Together: How Do These Cameras Stack Up?
