Canon PowerShot A810 vs SX520 HS: A Detailed Hands-On Comparison for the Informed Photographer

In a world awash with pocketable cameras, the choice between two models such as the Canon PowerShot A810 and the Canon PowerShot SX520 HS can be surprisingly complex. With each targeting the entry-level compact segment but aimed slightly differently, the nuances of real-world performance, image quality, and usability become critical to know before buying. As someone who has personally tested thousands of cameras across genres and scenarios, I’ll walk you through an in-depth comparison spanning technical specs to field-tested results, arming you with the kind of insight only gained through hands-on experience.

Let’s get started by laying out the physical and handling differences between these two Canons.

How They Feel in Your Hands: Size and Ergonomics

The Canon A810 and SX520 HS both straddle the compact bracket, but not with the same footprint or heft. The A810 is a classic small-sensor compact designed for simplicity and pocketability, while the SX520 HS is a superzoom compact catering to photographers who want an all-in-one travel camera.

At 95 x 62 x 30 mm and just 171 grams powered by two AA batteries, the A810 is incredibly light and slim - ideal for casual users or travelers prioritizing packability. It's easily slipped into most pockets. The SX520 HS, by contrast, is significantly larger and heavier at 120 x 82 x 92 mm and 441 grams (with a custom Rechargeable Battery Pack). This make sense when you consider the integrated 42x zoom lens the SX520 HS houses.

On top, the control layouts further reflect their different user philosophies:

The A810 opts for a minimalist approach - a mode dial with basic scene selections, an unlit, small LCD on the rear without touchscreen support, and no manual control rings or dials. Meanwhile, the SX520 HS adds manual exposure modes (shutter and aperture priority, full manual), exposure compensation dial, and a more comprehensive button layout.

Ergonomically, the SX520 HS’s deeper grip and larger form factor provide a more stable shooting platform, helpful especially when zoomed in. But for quick grabs or street photography, the A810’s svelte design wins hands down.

The Heart of the Image: Sensor and Image Quality

Both cameras use a 16 MP 1/2.3-inch sensor, with identical dimensions of 6.17 x 4.55 mm, but their sensor types differ - the A810 uses an older CCD sensor, while the SX520 HS employs the more modern BSI-CMOS sensor.

This distinction matters.

CCD sensors, like in the A810, traditionally offer good color rendition and lower noise at base ISO, but they tend to be slower, consume more power, and underperform at higher ISOs compared to CMOS. The SX520 HS’s BSI-CMOS sensor is optimized for better light gathering, leading to improved noise performance, faster readout speeds, and generally superior image quality especially in low light.

In practical shooting tests, the A810 produces decent daylight images with acceptable sharpness and color fidelity, but starts showing noise and loss of detail by ISO 800. The SX520 HS extends usable ISO to 1600 with less noise and preserves detail better thanks to its sensor and Canon’s DIGIC 4+ processor boosting noise reduction algorithms.

The SX520 HS also supports a broader range of aspect ratios - including 1:1 and 3:2 - offering more compositional versatility than the A810’s limited 4:3 and 16:9.

Viewing and Framing: LCD Screens and Interface

Neither camera sports a viewfinder, electronic or optical, so the rear LCD becomes the critical interface for composing shots.

The A810 sticks with a 2.7-inch fixed, non-touch screen at a low 230K-dot resolution, which can be challenging under bright sunlight. The screen displays basic information but lacks any touch input, so navigating menus felt somewhat clunky during my hands-on.

Shooters will appreciate the SX520 HS’s much larger 3-inch screen with a higher 461K-dot resolution. While also fixed and nontouch, this sharper, brighter panel provides clearer framing, sharper focus confirmation, and smoother menu operation. Switching focus points, exposure compensation, and toggling settings is much more straightforward on the SX520 HS, lending itself to faster shooting scenarios.

Zoom Range and Lens Capability: From Everyday to Extreme Reach

Here’s where the two diverge more obviously.

The Canon A810’s fixed lens covers a 28-140 mm equivalent focal length with a moderate 5x optical zoom range, and a bright maximum aperture of f/2.8 at wide angle stepping down to f/6.9 at telephoto. The lens does well for general snapshots, portraits, and casual shooting but is limited beyond short telephoto.

The SX520 HS boasts a whopping 24-1008 mm equivalent focal range - an industry-leading 42x zoom - catering to wildlife, travel, and situations demanding extreme versatility. Aperture is less bright, starting at f/3.4 wide and narrowing to f/6.0 at full zoom, which means it’s less suited for low light telephoto shots without boosting ISO.

This lens breadth makes the SX520 HS an outstanding choice for photographers wanting a single “go anywhere” camera - but at a cost of bulk and somewhat slower apertures. The A810’s smaller zoom range pairs with its size, favoring operators prioritizing lightness over reach.

Autofocus and Performance: Keeping up with Your Shot

Autofocus (AF) performance often defines camera usability more than sensor specs. Both cameras use contrast-detection AF systems with 9 focus points and face detection enhancements.

The A810 has basic AF modes without manual focus, limited tracking, and single shot AF sensitivity. It includes continuous AF and face detection, but its CCD sensor and older processor limit speed.

Comparatively, the SX520 HS supports manual focus, faster continuous AF, face detection, and live-view AF with slightly better tracking due to the DIGIC 4+ engine.

Continuous shooting speeds double in favor of SX520 HS - 2 fps vs A810’s 1 fps - which isn’t blazing but useful for casual action. Shutter speeds max out equally at 1/2000 sec, but the SX520 HS provides shutter and aperture priority plus full manual mode, empowering creative control that’s lacking on the A810.

Flash and Low-Light Capabilities

Both cameras include built-in flashes, but the SX520 HS has a more powerful range (5.5 m) compared to the A810 (3.0 m). Flash modes also reflect their design intent - the SX520 HS has slow sync flash for creative exposures, missing from the simpler A810.

In dim conditions, the A810’s maximum native ISO 1600 with its limited lens aperture and older sensor yields noisier images with less detail. The SX520 HS’s better sensor and noise handling allow cleaner images up to ISO 3200, making it more flexible for low-light events or indoor shots without a flash.

Video Recording: Not Just Still Cameras Anymore

When it comes to video, the A810 shoots HD (1280x720) at 25fps in H.264, suitables for casual family videos. The SX520 HS upgrades video to Full HD (1920x1080) at 30 fps with additional frame rate options including 720p and VGA at 30 fps - a clear edge for enthusiast videographers.

Neither camera offers 4K or advanced video features. Audio capture relies solely on built-in mics, and neither provides external mic or headphone jacks - a limitation for vloggers or those seeking higher quality sound recording.

The SX520 HS’s optical image stabilization is helpful during handheld video, especially at extended zoom, improving footage smoothness and reducing jitter.

Battery Life and Storage: Powering Long Shoots

Battery operation profoundly affects usability.

The A810 runs on two AA batteries, offering flexibility with standard or rechargeable NiMH cells. I appreciate this for travel since AA batteries are globally available. Canon rates around 220 shots per charge - adequate for casual use but limited for extensive shooting.

The SX520 HS uses Canon’s proprietary NB-6LH lithium-ion battery pack, rated at 210 shots per charge. Although similar in capacity, the dedicated battery pack is lighter and rechargeable, but travel shooters must ensure pack availability or carry spares.

Both accept standard SD, SDHC, and SDXC cards with a single storage slot.

Build Quality and Weather Resistance

Neither camera is officially weather-sealed or ruggedized. The A810’s plastic external body feels modest and consumer-grade, suitable for general use but less durable under harsh conditions. The SX520 HS is more robust and heavier, but also lacks any environmental sealing.

For photographers shooting outdoors regularly or in adverse weather, neither should be your primary choice without additional protection.

Connectivity and Modern Features

Both cameras are relatively barebones by 2020s standards. Neither offers Wi-Fi, Bluetooth, NFC, or GPS. The SX520 HS adds HDMI output for direct display to HD TVs - useful for reviewing images and video - but lacks USB 3.0 or tethering capabilities.

This lack of modern connectivity is understandable given their budget nature and release dates but may be a downside for those desiring instant sharing or remote control.

Image Samples in Real Scenarios: Portrait, Landscape, Wildlife, and More

Having dissected specs and handling, let’s look at how these cameras perform across photography genres.

• Portraits: The A810 delivers natural skin tones with smooth bokeh at wide open aperture (28 mm f/2.8), but limited zoom and no manual exposure make creative depth-of-field control tricky. The SX520 HS, while having a smaller maximum aperture overall, impresses with more zoom reach for tighter headshots but produces more background details due to a smaller aperture, making it less ideal for creamy bokeh.

• Landscapes: Both cameras perform decently in daylight scenes, but the SX520 HS’s higher resolution and better dynamic range recover more highlight and shadow details. The fixed high f-number telephoto lens of both limits creative aperture usage, but the SX520 HS’s broader focal coverage shines for wide to tight landscape framing.

• Wildlife & Sports: Here, the SX520 HS’s massive zoom range and faster AF and burst modes offer a clear advantage - handheld shots even at 1000mm equivalent zoom are manageable with stabilization. The A810’s 5x zoom and slower continuous shooting make it less effective for dynamic, fast-action subjects.

• Street Photography: The A810’s compact size and lighter weight help discreet shooting, important in candid street contexts. The SX520 HS, while versatile, is bulkier and possibly intrusive in tight urban environments.

• Macro: The A810’s close focusing distance of 3 cm lets you comfortably get close to subjects, while the SX520 HS’s macro range of 0cm (likely meaning “very close”) theoretically offers tighter macro capabilities. Image stabilization assists in getting crisp close-ups on both, but manual focus on the SX520 HS helps ensure accuracy.

• Night/Astro: Neither camera is designed for astrophotography, and both struggle with high ISO noise. The SX520 HS is superior but still limited compared to larger sensor cameras.

• Video: The SX520 HS’s Full HD footage with stabilization gives it the edge over the HD A810, better suited for casual but nuanced video capture.

• Travel: SX520 HS’s zoom versatility and manual controls make it an excellent all-rounder for trips when size and weight are less critical; A810 excels when lightness and simplicity matter most.
