Canon PowerShot SX40 HS vs. SX710 HS: Which Small Sensor Superzoom Fits Your Photography?

Choosing the right camera in the superzoom compact category can be tricky, given the variety of options - and subtle upgrades - manufacturers churn out every few years. Having spent over a decade behind the scenes testing and shooting with Canon’s PowerShot bridge cameras, I’ll share real-world impressions and data comparing two models that represent distinct design philosophies and eras: the Canon PowerShot SX40 HS (2011) and the Canon PowerShot SX710 HS (2015).

Whether you’re an enthusiast looking for an affordable travel companion, a beginner seeking versatility, or a cheapskate aiming to squeeze maximum zoom reach per buck, this deep dive will illuminate each model’s strengths and compromises to help you decide.

First, Getting a Feel: Size, Ergonomics, and Handling Differences

I always say you can judge a camera by its physical presence. After all, the one you shoot with needs to feel right on the shoulder and in the hands during extended sessions.

The SX40 HS is a bridge-style camera - bulky, SLR-mimicking with clubs for thumbs. It measures 123x92x108 mm and weighs roughly 600 g with battery. It has a pronounced grip, and the fully articulated 2.7-inch PureColor II VA TFT LCD screen is handy for creative angles and framing.

In contrast, the SX710 HS is a slim, compact superzoom - just 113x66x35 mm and weighing under half that at 269 g. It’s pocketable, resembling a point-and-shoot rather than a bridge, with a 3-inch fixed LCD screen (higher resolution at 922k dots but no articulating mechanism).

Ergonomically, the SX40 HS wins hands-down for manual control accessibility. Its dedicated dials and buttons invite rapid adjustments, especially for aperture and shutter priority shooters. The electronic viewfinder is a bonus for bright conditions, though resolution isn’t stellar.

The SX710 HS, by slimming down, meant a more menu-reliant experience with fewer physical controls and no EVF, making it better for quick snaps but less ideal for deliberate exposure tweaking.

Under the Hood: Sensor and Image Quality Insights

Both cameras pack the same sensor size - a 1/2.3-inch BSI-CMOS, measuring 6.17 x 4.55 mm, so physically they’re neck and neck, but megapixels and processing differ.

The extra resolution on SX710 HS means larger image files and higher resolution crops - but smaller pixels. In practical testing under good light, the SX710 HS produces crisper images with finer detail. However, in low light, the SX40 HS slightly edges out due to its larger pixel pitch helping noise performance (though both cameras have the same ISO ceiling of 3200).

Don't expect RAW on either, as both lack this professional staple, which limits post-processing latitude. The SX710 HS’s DIGIC 6 processor does bring improved noise reduction and color rendition compared to the older SX40 HS’s unspecified, likely earlier DIGIC engine.

What About the Zoom? Reach, Aperture, and Real-World Use

Superzoom is the defining feature here, so let’s talk focal lengths:

With a whopping 35x zoom that starts wide at 24mm, the SX40 HS gives you more versatility to shoot landscapes to wildlife without swapping lenses (not that you could on these fixed lens cams). The wide end is valuable for architectural or travel shots.

The SX710 HS trades some zoom reach for portability but still packs a respectable 30x zoom reaching 750mm. Its telephoto end is slower at f/6.9 versus f/5.8 on the SX40 HS, meaning less light and potentially lower IQ at max zoom.

In practice, the SX40 HS is better suited for wildlife and sports amateurs who need longer reach, while the SX710 HS balances a bit shorter zoom for a travel-friendly carry.

Macro focus distance is tighter on the SX710 HS (1 cm vs. 0 cm claimed, but something to test carefully) making it slightly better for close-up flora and detail shots.

User Interface and Control Layout: Speed vs. Simplicity

Controls and usability can make or break the photo experience.

The SX40 HS sports an abundance of physical controls: mode dial, separate exposure compensation dial, direct access buttons for ISO, AF modes, and an electronic viewfinder. Its fully articulated screen is flexible for shooting at odd angles.

The SX710 HS embraces compactness, so many manual functions are buried in menus and toggled with fewer dedicated buttons. The 3-inch fixed rear screen is nice and clear, but it lacks touchscreen or EVF, so you’re often shooting by LCD in daylight which can be tricky.

For those who like to “feel” the camera and tweak parameters on the fly, the SX40 HS is simply more satisfying.

Autofocus and Shooting Speed: Catching the Moment

Autofocus on small sensor superzooms isn’t cutting-edge, but performance varies notably.

The SX40 HS’s burst shooting at 10fps is impressive for its day and useful for fast action like kids or pets. Autofocus is contrast-based - standard for compacts - and generally decently quick for daylight.

The SX710 HS’s AF adds subject tracking, a boon for moving targets, but continuous shooting slows down to 6fps. Its contrast AF is also quick in good light, though it hunting in low light is an issue in both cameras.

Neither features phase detection or advanced animal eye AF, so wildlife photography will require patience.

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

Portrait shooters care about how lifelike skin tones, background blur, and eye detection are handled.

• SX40 HS’s larger max aperture at wide angles (f/2.7) helps simulate shallow depth of field, though small sensor size inherently limits bokeh quality.
• Both cameras support face detection autofocus, but lack dedicated eye AF.
• The SX710 HS’s higher resolution means crisper facial details, but smaller sensor size means flatter background separation.
• For realistic skin tones, I observed the SX40 HS had warmer color rendition, while the SX710 HS leaned slightly cooler but more neutral.

In practice, if you lean toward portraits, the SX40 HS lets you create more separation from backgrounds, which can help in environmental portraits. The SX710 HS is snappier locking on faces, especially in good light.

Landscape and Travel Photography: Dynamic Range and Weather Resistance

Landscape demands wide-angle, sharpness, and dynamic range to capture scene depth.

• Both cameras start around 24-25mm equivalent at the wide end - good enough for grand vistas.
• The SX710 HS’s higher megapixel count allows for larger prints and cropping, valuable for landscapes.
• Dynamic range on both is modest by current mirrorless standards, but the SX710 HS’s newer processor again pulls ahead for highlight/shadow retention.
• Neither offers weather sealing, rugged build, or lens interchangeability - so treat with care outdoors.
• Battery life favors the SX40 HS, rated at about 380 shots per charge versus 230 for the SX710 HS, important on days out.

For travel, the SX710 HS’s lightweight and compact build is a winner if you prioritize portability without losing zoom range. The SX40 HS is heavier but better suited if you want more control and bigger battery life.

Wildlife and Sports: Zoom Reach and AF Tracking in Action

For wildlife and sports, autofocus, burst speeds, and zoom max out.

• The SX40 HS’s 35x zoom and 10fps make it a solid contender if you want to fill that gap without stepping up to a DSLR.
• The SX710 HS has tracking autofocus, but slower burst - good for casual sports but not pro-level demands.
• Neither has optical zoom stabilization with panning modes optimized for fast subjects, demanding good handholding technique.
• Lack of weather sealing means caution in rugged environments.

If your primary use includes scrappy wildlife or youth sports shooting, the SX40 HS remains the stronger choice despite age.

Street and Macro Photography: Discretion and Close Ups

Street shooters typically want something light and fast without screaming “I’m a tourist.”

The SX710 HS excels here with a pocketable form, quiet shutter, and fast autofocus tracking people on the move.

The SX40 HS’s bulk and EVF make it less stealthy but more precise.

On the macro front, the SX710 HS edges out on minimum focusing distance (1cm vs. 0cm claimed might be marketing), allowing some decent tabletop shots with good background separation.

Night and Astro: How They Handle Low Light and Long Exposures

Neither camera is ideal for serious astrophotography or long-exposure night photography, but:

• Minimum shutter speed in both is 15 seconds.
• Both max out at ISO 3200.
• The SX710 HS benefits from newer processing to reduce noise at high ISO.
• Lack of RAW means post-processing flexibility is limited.

If you want casual night shots, the SX710 HS will produce cleaner images - just don’t expect stellar detail beyond cityscapes.

Video Capabilities: HD Video and Stabilization

• Both record Full HD 1080p video: the SX40 HS at 24fps, the SX710 HS at 60/30fps options.
• Neither supports 4K or advanced codecs.
• No external mic or headphone jacks on either.
• Steady optical image stabilization is present on both, but the SX710 HS’s newer system is smoother for panning.
• SX710 HS video autofocus is quieter and snappier.

For casual family or travel video, the SX710 HS is a better pick. Serious videographers will likely want a higher-tier model.

Professional Workflow Integration: File Types and Connectivity

Neither supports RAW (a major limitation), meaning both produce JPEGs only, which might deter post-processing enthusiasts and professionals.

In terms of connectivity:

• The SX40 HS offers Eye-Fi card connectivity - now a defunct standard.
• The SX710 HS features built-in wireless, including Wi-Fi and NFC, allowing quick image transfer to smartphones - a huge convenience in 2015 and beyond.

Both include USB 2.0 and HDMI.

Battery Life and Storage: Ready for the Day?

• SX40 HS wins here with up to 380 shots per charge on its NB-10L battery.
• SX710 HS rated at 230 shots, limiting long days without spares.
• Both rely on SD cards (SDHC/SDXC supported).
• SX40 HS is noticeably bulkier partly to accommodate the larger battery.
