Canon PowerShot A2100 IS vs Canon PowerShot SX610 HS: A Hands-On Comparison for the Savvy Photographer

When hunting for a compact travel-friendly camera - or for a budget-conscious backup to your bigger rig - the Canon PowerShot lineup offers tempting options. Two models often pop up in conversations: the Canon PowerShot A2100 IS, a humble compact from 2009, and the later Canon PowerShot SX610 HS from 2015, boasting superzoom abilities wrapped in a similar pocket-sized chassis. Having personally tested thousands of cameras over the past 15 years, I’m here to guide you through a thorough comparison of these two small sensor Canon compacts.

Whether you’re a casual snapper, a budding enthusiast, or someone who needs a second camera without breaking the bank, this comparison dives deep into key factors affecting image quality, handling, autofocus, and more. I’ll share real-world observations, technical insights, and practical recommendations so you can make a confident choice for your photography needs.

A Tale of Two Compact Canons: Size, Build, and Handling

First impressions count - and that starts with size, weight, and ergonomics. Let’s see how these cameras stack up physically.

The Canon A2100 IS is a compact fellow measuring roughly 102 x 64 x 32 mm and weighing 185 grams. Its retro-ish squared shape is comfortable for quick grabs, and it runs on affordable AA batteries - great if you find yourself in remote locales or don’t want to fuss with proprietary chargers.

The Canon SX610 HS is a bit longer but thinner at 105 x 61 x 27 mm, tipping the scales slightly heavier at 191 grams. It forgoes AA batteries in favor of a dedicated rechargeable battery pack (NB-6LH), which means fewer bulky extras but requires consideration for charging downtime.

Both lack viewfinders (I know, that’s a bummer for some), relying entirely on their rear LCD screens. The A2100’s fixed 3-inch screen is low res (230K dots), quite grainy in daylight, and non-touch. The SX610 ups the ante to a sharper 3-inch screen with 922K dots, meaning brighter, more detailed framing and easier manual focusing.

The SX610’s slimmer profile and more refined button layout (we’ll get to that) feel like it was designed for modern shooters accustomed to crisp LIVE VIEW. Meanwhile, the A2100’s chunkier body and wider grip area give it a pleasant heft, though some controls feel dated and clumsy under my thumbs.

If you prize portability and updated ergonomics, the SX610 wins. But if you’re a cheapskate in the field who values AA battery reliability over sleekness, the A2100 still has charm.

Top-Down Controls: Navigating Both Cameras’ Interfaces

Next, I took a look from above to get a feel for the user interface and control scheme. For me, how a camera feels under the fingers in real shooting scenarios is a dealmaker.

The A2100’s shutter button sits comfortably on a slight slant, but the zoom lever feels stiff and slow - especially annoying when tracking moving subjects. Mode selection is limited to basic point-and-shoot options; no aperture priority or manual modes here, just simple preset modes aimed at beginners.

In contrast, the SX610 HS sports a cleaner, less cluttered top plate. The shutter button and zoom toggle are more responsive, thanks in part to the DIGIC 4+ processor powering faster operations. Though it doesn’t offer manual exposure modes either, it does provide contrast-detection continuous autofocus (more on that soon) and better burst shooting (2.5 fps vs 1.0 fps on A2100), making it more flexible for casual action shots.

Neither camera sports advanced controls for pro users, but the SX610’s upgraded responsiveness and smoother dials give a distinct leg up once you start pushing beyond point-and-shoot.

Sensor Technology: Where Image Quality Begins

If you’ve read any reviews, you know sensor size and tech profoundly impact photo outcomes. Both models use the common 1/2.3” sensor size (6.17 x 4.55 mm), but their underlying sensor technology couldn’t be more different.

The Canon A2100 IS employs an older CCD sensor with 12 megapixels. CCD sensors are known for their color rendition but tend to be slower and noisier at higher ISO levels. The maximum ISO of 1600 is pushing it, and the camera lacks RAW support, limiting post-processing flexibility.

By contrast, the Canon SX610 HS uses a 20-megapixel backside-illuminated (BSI) CMOS sensor. This newer sensor design improves light sensitivity, yielding cleaner images in low light and wider dynamic range. It doubles the resolution of the A2100, allowing for more cropping flexibility or large prints.

While both share the same physical sensor size - which inherently limits noise performance compared to larger APS-C or full frame sensors - the SX610’s sensor technology and higher pixel count translate to a noticeably sharper, more versatile image at base ISO settings.

Both cameras have an anti-aliasing filter, which helps avoid moiré patterns but softens fine detail. For the budget and class, this trade-off is expected.

Real-World Image Quality: Sharpness, Color, and Noise

In practical shooting tests, the SX610 HS delivers noticeably crisper, more saturated images with less noise beyond ISO 400. Skin tones on the SX610 come across more natural and warmly rendered - important if you prioritize portraiture or casual family snaps.

The A2100’s images tend to feel a bit softer and slightly cooler in color. Its 12-megapixel resolution still produces good prints up to 8 x 10 inches, but digital zoom or heavy cropping quickly degrade the final photo.

Both models suffer from limited dynamic range inherent to the small sensors, but the SX610’s sensor does a better job preserving highlight and shadow details in landscapes and bright outdoor scenes.

For you wildlife or sports shooters, the A2100’s lone 1 fps burst speed and laggy autofocus likely won’t cut it. The SX610’s 2.5 fps continuous shooting paired with contrast-detect autofocus (including face detection) gives you slightly more leeway for those fleeting moments, although we’re still miles away from pro APS-C mirrorless systems here.

Autofocus and Tracking: Peeling Back the Tech Layers

When testing AF performance, I used both cameras in varied lighting and subject motions. The Canon A2100 IS features a fairly basic 9-point contrast-detection autofocus system with face detection. Unfortunately, it has no continuous AF mode - so once a focus lock is set, it won’t keep tracking moving subjects smoothly.

The Canon SX610 HS uses an improved 9-point contrast-detection AF as well, but uniquely adds continuous AF and AF tracking. This lets you capture moderately fast-moving subjects better, although it sometimes hunts in lower light.

Neither camera offers phase-detection AF, which would have improved speed and tracking reliability, but that’s expected at this price point and sensor size.

Surprisingly, despite lacking an electronic viewfinder, the SX610’s AF system combined with its higher-res rear LCD made manual focus confirmation easier, giving me more confidence for macro or telephoto work.

Zoom Lenses Compared: Reach, Aperture, and Versatility

If you’re hunting for your next travel or walk-around camera, zoom capabilities matter a lot.

The Canon A2100 IS sports a modest 6x optical zoom (36–216mm equivalent) with a variable aperture of f/3.2–5.9. It’s a decent range to cover portraits, casual telephoto snaps, and general outings, but it can feel a little cramped, especially if you’re itching to zoom in on wildlife from a distance.

The Canon SX610 HS boasts an 18x optical zoom (25–450mm equivalent), tripling the telephoto reach of the A2100. Aperture here narrows to f/3.8–6.9 - slightly slower but expected at that extended zoom range. This makes it an excellent superzoom compact that can double as a budget wildlife or sports backup camera.

The wider 25mm equivalent wide angle on the SX610 is advantageous for landscapes, architecture, and cramped interiors where fitting more in frame matters.

Screen Quality and Usability: Making Every Shot Count

LCD quality makes or breaks composition and review usability in compacts without viewfinders. The A2100’s 3-inch 230K pixel screen is serviceable but feels grainy, less colorful, and dim outdoors, especially under bright sunlight. It also lacks touchscreen functionality, meaning fiddly menus.

The SX610’s 3-inch 922K pixel display is much more vibrant and responsive. Although not a touchscreen, its higher pixel density offers better manual focusing aid and easier framing, contributing to a more pleasant shooting experience.

For those doing macro and telephoto work - where precise focus confirmation is vital - the SX610’s screen is a noticeable upgrade over the A2100.

Video Capabilities: What You Can Expect from Each

If video is at all in your vocabulary, the differences are stark.

The A2100 IS shoots only standard definition 640x480 @30fps using Motion JPEG, which is outdated and results in large file sizes with mediocre quality.

The SX610 HS offers full HD 1080p @30fps video with modern H.264 compression and MPEG-4 container format. While there’s no external mic input (which is a shame for vloggers or serious videographers), the video quality is surprisingly decent for a superzoom compact at this price, making it a capable casual movie shooter.

Neither camera records 4K or offers advanced video features such as zebras, focus peaking, or log profiles.

Battery Life and Storage: Staying Powered and Ready

Here the A2100 IS rockets ahead in convenience if you have spare AA batteries handy. While they don’t last forever, fresh alkalines or rechargeables can be swapped in instantly with no waiting. Plus, they are readily available worldwide.

The SX610 HS uses a proprietary NB-6LH rechargeable lithium-ion battery offering around 270 shots per charge - respectable but you’ll want a spare for longer days out.

Both cameras accept standard SD card formats, with the SX610 expanding compatibility to SDXC cards, allowing storage of large high-res photos and videos.

Connectivity and Extras: How Modern is Modern?

Connectivity is minimal on both fronts. The A2100 IS has no wireless features, no HDMI, and only a basic USB 2.0 port for file transfers.

The SX610 HS upgrades with built-in Wi-Fi and NFC for easier photo sharing and remote control from smartphones, plus an HDMI output for convenient playback on TVs.

While neither offers GPS, touchscreen, manual exposure, or ruggedized build, the SX610’s incremental modernizations cater to better versatility and connectivity in the mid-2010s compact market.
