Canon PowerShot A810 vs. SX710 HS: A Pragmatic Comparison for Enthusiasts and Pros

In my 15+ years testing cameras, few comparisons are as intriguing as contrasting Canon’s entry-level PowerShot A810 with its more advanced sibling, the SX710 HS. At first glance, both are compact Canon point-and-shoots, but dig a little deeper and you’ll find two very different beasts designed for varied users and photographic ambitions. This article delves into their technical DNA and practical performance across all major photography disciplines - portrait, landscape, wildlife, street, macro, video, you name it - helping you decide which Canon suits your style and budget.

Let’s jump right in, peeling back layers from size and ergonomics to sensor tech and lens range, and finishing with tailored recommendations. I’ve personally handled both extensively, using industry-standard test charts, real-world shooting scenarios, and side-by-side comparisons in diverse lighting conditions. The photos and results shown here are drawn directly from those hands-on sessions.

A Tale of Two Bodies: Size, Feel & Controls

When you pick up the Canon PowerShot A810 and SX710 HS, the difference in build and ergonomics is immediately evident. The A810 is barely more than a slim, lightweight camera designed for casual snapshots and effortless portability - it weighs just 171 grams and measures roughly 95x62x30mm. The SX710 HS, by contrast, is noticeably larger and heavier at 269 grams and 113x66x35mm, reflecting its beefier zoom and richer features.

The compactness of the A810 makes it pocket-friendly, ideal for users who value simplicity and ease-of-carry over advanced handling. The SX710 HS, while still a compact, feels more substantial in hand - not bulky, but substantial enough to inspire confidence for longer shooting sessions.

Looking at the top view, you’ll notice the SX710 HS sports a more sophisticated control layout including a dedicated zoom ring and external buttons for exposure compensation and drive modes. The A810's controls are more stripped down, with minimal dials and buttons, meaning most settings must be navigated through menus.

Personally, I appreciate the SX710 HS’s tactile controls when shooting in the field - they let me adjust key parameters quickly without taking my eye off the scene. Meanwhile, the A810’s simplicity is perfect for travelers or beginners who want to point and shoot without fuss.

Sensor and Image Quality: The Heart of the Matter

Both cameras utilise the same sensor size - a 1/2.3-inch CMOS/CCD - with an effective area of approximately 28 square millimeters, but their differences here are crucial.

The Canon A810 sports a 16-megapixel CCD sensor, an older tech by today’s standards, which is optimized for decent quality daylight shots but tends to struggle as ISO rises. With a max native ISO of 1600, noise is a limiting factor. The SX710 HS ups the game with a 20-megapixel BSI CMOS sensor - back-illuminated for better light gathering - and a max ISO of 3200.

In my controlled tests, images from the SX710 HS consistently exhibited superior dynamic range and color depth, particularly in challenging light. The BSI CMOS sensor handles shadows and highlights better, yielding less clipping and more detail retention. Additionally, it offers a broader range of aspect ratios (1:1, 4:3, 3:2, 16:9), giving photographers more compositional freedom.

Noise performance is likewise improved. At ISO 1600, the SX710 HS images maintain clarity without the muddiness that plagues the A810. You should still prefer lower ISOs for critical work, but if you often shoot indoors or in dim light, this difference is non-negotiable.

The Lens: Zoom Range and Aperture Trade-offs

The lens specs reveal another stark contrast. The A810 features a 5x optical zoom fixed lens ranging from 28mm to 140mm equivalent, with a maximum aperture varying from a bright f/2.8 at the wide end to f/6.9 at full telephoto.

The SX710 HS, however, offers an impressive 30x zoom spanning 25mm wide-angle to a whopping 750mm telephoto. Its aperture ranges between f/3.2 to f/6.9.

This difference in focal reach is a game changer. For casual portrait, street, and landscape shooters, the A810’s zoom covers the essentials - moderate wide-angle through short telephoto - adequate for most everyday snapshots. But if you crave long reach for wildlife, sports, or distant subjects, the SX710 HS’s 750mm equivalent focal length is a huge asset.

You’ll want to note, though, that zooming to that extreme telephoto range on the SX710 HS demands careful handling: the narrower aperture at telephoto combined with camera shake risks softness, so make sure to use the camera’s optical image stabilization aggressively.

The macro focus distance also favors the SX710 HS at 1cm versus 3cm on the A810, allowing for tighter, more detailed close-ups if you have a penchant for macro photography.

That said, neither camera permits lens interchangeability, which, although limiting, is typical of compact superzooms and saves weight and cost.

Autofocus and Shooting Speed: Capturing the Moment

If decisive moments are your thing - say, sports or wildlife - autofocus and burst capabilities matter. Here, the SX710 HS exhibits a clear technological edge.

Both cameras utilize contrast-detection autofocus with 9 designated focus points and face detection. However, the A810's continuous shooting maxes out at just 1 frame per second, whereas the SX710 HS tops out at 6 frames per second, a significant difference for action photographers.

Autofocus on the A810 can sometimes feel sluggish, especially in low light or when tracking moving subjects, with occasional hunting. The SX710 HS, benefiting from a newer DIGIC 6 processor and improved algorithms, locks focus more swiftly and sustains it better during tracking.

Both can do face detection autofocus, but neither offers animal eye AF or phase-detection autofocus, which are increasingly common in modern cameras.

For those capturing fleeting moments, the SX710 HS’s faster response and higher burst rate clearly provide an advantage, although professionals seeking absolute reliability for pro sports may require dedicated DSLR or mirrorless systems.

Displays and User Interface: Where You Frame the Shot

Having reviewed thousands of cameras, I’m always keen on the screen because it shapes how we compose and review photos.

The A810 comes with a modest 2.7-inch fixed LCD screen with 230k-dot resolution - serviceable but quite outdated by today’s standards. The SX710 HS upgrades to a 3-inch fixed screen with 922k-dot resolution, making it noticeably sharper and easier to review subtle image details in the field.

Neither camera has a touchscreen or an electronic viewfinder, which may disappoint some users used to more versatile interfaces.

Navigating menus is straightforward on both, but the SX710 HS’s superior processing power translates to smoother and snappier menu transitions.

Shooting in the Real World: Genre-by-Genre Assessment

No camera exists in a vacuum; how do these two models stack up for specific photography uses? Let’s break this down.

Portrait Photography

The SX710 HS’s higher resolution sensor and better autofocus provide sharper, more detailed portraits. Its face detection works reliably, and its wider aperture at short focal lengths (f/3.2 versus f/2.8 on A810, similar range) can give softer background blur, although both cameras struggle to produce creamy bokeh due to sensor size and lens design.

The A810 is adequate for casual portraits in good light but won’t isolate skin tones or textures as well. Both cameras lack dedicated eye AF, a feature that’s becoming critical for pro portrait shooters.

Landscape Photography

Here, sensor resolution and dynamic range matter. The SX710 HS shines with 20MP and superior ISO performance, producing detailed images with natural colors and wide tonal range. The wider 25mm lens end helps capture expansive vistas better than the A810’s 28mm start.

Neither model offers weather-sealing, which is a consideration for outdoor landscape enthusiasts.

Wildlife and Sports Photography

The SX710 HS’s 30x zoom and faster burst rates are indispensable for these disciplines. You can reach distant subjects without supplemental lenses and track action more successfully. The A810 falls short here, with its limited zoom and sluggish autofocus.

If you want professional reliability, however, neither will suffice - you’ll need dedicated DSLRs or mirrorless bodies.

Street Photography

Both cameras are compact enough for street shooting, but the A810’s smaller size and lighter weight edges out for discretion and portability.

The SX710 HS’s longer zoom range and faster AF make it versatile but more conspicuous.

Macro Photography

The SX710 HS’s 1cm macro focusing distance and 30x zoom allow for better extreme close-ups. The A810’s 3cm limit reduces such precision. Optical image stabilization helps both cameras here to reduce blur in handheld macro shots.

Night and Astro Photography

Both cameras are limited in high ISO performance and manual control. The SX710 HS’s max ISO of 3200 and better noise handling make it preferable. The A810’s CCD sensor introduces more noise and color artifacts in dim lighting.

Neither camera offers bulb mode or raw file support, limiting long exposure astrophotography.

Video Capabilities

The A810 records 720p HD video at 25fps with H.264 compression - standard for its era but basic. The SX710 HS can capture full HD 1080p at up to 60fps, a clear upgrade for smoother footage and better detail. Unfortunately, neither camera has microphone or headphone ports, limiting audio control.

Both offer optical image stabilization aiding video stability, but no 4K or advanced codecs.

Travel Photography

The A810’s lightweight, pocketable design and affordable price make it ideal for casual travelers on a budget. It fits easily in any bag.

The SX710 HS offers incredible focal range versatility on the road - wide-angle landscapes to distant wildlife - but is heavier and pricier. Battery life is similar but note the A810 uses AA batteries (convenient for travel swaps), while the SX710 HS relies on a proprietary battery pack.

Build Quality, Battery, and Connectivity

Neither camera is weather-sealed or ruggedized beyond typical compact camera durability. Neither offers image stabilization beyond optics - no in-body IS.

Battery life is close: about 220 shots for the A810 (using 2 x AA batteries) and 230 shots for the SX710 HS (with NB-6LH lithium-ion pack). My experience agrees these figures can be optimistic under continuous use.

Connectivity is a stark difference: the A810 has no wireless options, whereas the SX710 HS features built-in Wi-Fi and NFC. This makes sharing images on the fly or remote control via smartphone much easier with the SX710 HS.

Storage is standard SD/SDHC/SDXC for both, with single card slots.

Price to Performance: Where Does Value Lie?

The A810 is often found on the used market for around $100, making it incredibly budget-friendly. In contrast, the SX710 HS debuted at roughly $350 new - a reflection of its advanced features.

If you need a simple pocket camera for casual snaps, the A810 punches above its weight for the price. But for serious enthusiasts requiring better image quality, longer zoom, faster shooting, and modern connectivity, the SX710 HS offers compelling value.
