Canon PowerShot A2100 IS vs. SX520 HS: A Hands-On Comparison Decade Apart

When I first picked up the Canon PowerShot A2100 IS back in early 2009, it felt like a trusty compact companion tailored to casual shooters craving simple snapshot magic. Fast forward five years, and Canon’s PowerShot SX520 HS entered the scene, promising a quantum leap in zoom range, image quality, and manual control for enthusiasts seeking versatility without bulk. Having tested and worked extensively with both models over the years, I wanted to revisit these two Canon compacts side by side to illuminate how camera technology evolved through the small sensor superzoom segment - and what that means for photographers today.

This isn’t just a specs war. I’ve approached this comparison by putting both cameras through my typical real-world workflows across diverse photography disciplines: portrait, landscape, wildlife, sports, street, macro, night, video, travel, and professional usage. I’ll peel back the numbers and specifications through the lens of hands-on experience, calling out where these cameras excel or struggle given their era and intended use. If you’re hunting for a dependable compact camera on a budget, or intrigued by how Canon’s compact line matured through time, read on.

Size, Ergonomics, and Handling: Comfort Over Compactness?

Anyone who’s carried small cameras knows that size and grip comfort often set the tone for enjoyable photography sessions. The A2100 IS and SX520 HS belong to slightly different compact subclasses, so their physical presence is telling.

At 102x64x32 mm and weighing 185 grams (with two AA batteries), the A2100 IS is incredibly pocketable - very much a “grab and go” everyday shooter. Its streamlined grip suits smaller hands, but the plastic body feels lighter (and less durable) when held for extended periods. Conversely, the SX520 HS nearly doubles the heft at 441 grams and measures a more substantial 120x82x92 mm. It’s bulkier, mainly due to its mammoth 42x zoom lens, but the rubberized grip and enlarged controls profoundly enhance stability and handling during telephoto shooting.

The SX520 HS’s size makes it less ideal for discreet street photography or hiking light sessions, yet for anyone prioritizing zoom reach and a steadier hold, it rewards with confidence behind the camera. The A2100 IS’s diminutive form factor is delightful for spontaneous outings yet lacks a firm grip during rapid shooting or longer telephoto zoom holds.

Design Sophistication and Control Layout

Going beyond size, the top view of both cameras reveals Canon’s evolving approach to user interface and control ergonomics.

The A2100 IS assumes a no-frills posture: a simple shutter button, zoom toggle, and mode dial dominate the top deck. With no manual exposure modes, shooting is largely automated or semi-automatic, limiting creative control. This camera caters clearly to beginners or casual photographers intrigued by point-and-shoot simplicity.

The SX520 HS, however, offers a richer toolkit. Alongside a modestly sized mode dial, it integrates dedicated buttons for ISO, exposure compensation, manual focus, and shutter priority - features that proved invaluable during my wildlife and sports tests requiring nuanced exposure adjustments. The zoom lever encircles the shutter button, but with more travel and precision, reflecting the camera’s telephoto ambitions.

Both models sadly lack any electronic or optical viewfinder, directing all framing through their rear LCDs - a usability constraint I’ll touch on later.

Sensor and Image Quality: Measuring the Jump Forward

Both cameras use Canon’s 1/2.3” sensor format, but the difference between the older CCD sensor of the A2100 IS and the later BSI-CMOS sensor of the SX520 HS manifests palpably.

The A2100 IS employs a 12MP CCD sensor, characteristic of late 2000s compacts, which delivers reasonable image quality in good light but struggles with noise above ISO 400, limited dynamic range, and somewhat muted colors. It does have a subtle anti-aliasing filter, which helps prevent moiré but can soften fine detail.

The SX520 HS’s 16MP BSI-CMOS sensor advances significantly in noise control and dynamic range, allowing usable ISO settings up to 1600 (and ISO 3200 with some noise tradeoff). The back-illuminated design improves light gathering efficiency, sharpening images and boosting color rendition. While neither camera offers RAW capture - a perennial limitation in this class - the SX520 HS’s JPEG engine produces noticeably clearer, crisper output, especially under challenging light.

Importantly, the SX520 HS ups the resolution to 4608x3456 pixels against the A2100’s 4000x3000, providing more room to crop or enlarge images without detail loss. For landscape and wildlife shooters, this is a tangible benefit.

Back LCDs and Interface: Seeing What You Shoot

Since both cameras lack any viewfinder, reliance on the rear screen is paramount for composing shots and navigating menus.

The A2100 IS sports a 3-inch 230k-dot fixed LCD, typical for its time. It’s adequately bright indoors but lacks visibility under bright sunlight, often forcing awkward angling or guesswork outdoors. The fixed placement means sharing shots or reviewing images can be clumsy.

In contrast, the SX520 HS features a sharper 3-inch 461k-dot LCD, almost doubling the pixel count for crisper image playback. The display is brighter and holds up better under sunny skies - a necessity when working in open environments. While it remains fixed rather than articulated or touchscreen, its improved resolution coupled with more intuitive menus enhances user interaction significantly.

Given my repeated frustrations trying to frame shots relying on LCD only, the SX520 HS’s display is a big usability step forward - though both still lag behind modern cameras featuring OLED viewfinders or tilt screens.

Performance in Different Photography Genres

Let’s dive into how these cameras perform pragmatically across varied photographic disciplines, referencing my experience, and sample gallery images.

Portrait Photography

Portraiture demands pleasing skin tones, reliable face/eye detection, and gentle, natural bokeh effects.

The A2100 IS’s 9-point contrast-detection autofocus with face detection operates reliably in good light but hunts in dimmer rooms, sometimes missing critical focus on eyes. The f/3.2-5.9 lens aperture and small sensor limit background blur, resulting in somewhat flat images.

The SX520 HS’s autofocus system offers continuous AF and face detection with center-weighted AF points. Its slightly larger sensor and improved processing yield more accurate skin tone rendering and better color balance. While the lens’s aperture (f/3.4-6.0) is similar, the longer focal length (up to 1008mm equivalent) enables tighter headshots with subject isolation and softened backgrounds at telephoto.

If portrait shooting is your priority, the SX520 HS is a better choice, offering superior AF and image quality, but neither rival high-end interchangeable lens cameras’ bokeh quality.

Landscape Photography

Landscape shooters prize dynamic range, resolution, and weather durability.

Both cameras lack weather sealing, ruling out harsh environments without considerable care. Their identical sensor sizes constrain dynamic range; however, the SX520 HS’s BSI-CMOS sensor nudges ahead in shadow detail retrieval and highlight retention.

Resolution-wise, the SX520 HS’s 16MP sensor produces images that crop better and print larger without losing edge sharpness. Its broader focal length starting at 24mm equivalent is well-suited for wide vistas, whereas the A2100 IS’s 36mm start is more moderate.

Highlighting shadow detail was a common issue on the A2100 IS under bright skies - images often needed post-processing to balance extremes. The SX520 HS handled these lighting situations with less noise and richer tonal fidelity.

For landscape enthusiasts wanting portability and versatility, the SX520 HS clearly leads.

Wildlife and Sports Photography

Speed, autofocus tracking, and burst rate define the success with wildlife and sports shooting.

Here, the A2100 IS falters. Single AF only and a paltry 1 fps continuous shooting mode limit catching fast action. Its contrast-detection AF is too sluggish for precise subject tracking at longer focal lengths.

The SX520 HS’s continuous autofocus and 2 fps burst mode represent modest improvements, though still not fast by professional sports camera standards. Its staggering 42x zoom (24-1008mm equivalent) proved capable for distant wildlife shots in my backyard trials, although maintaining sharp focus at full zoom required careful stabilization.

Without image stabilization, the A2100 IS would be shaky at 216mm; thankfully, both cameras include optical IS, with the SX520 HS’s IS slightly more effective in my experience.

While the SX520 HS is no Canon EOS R5 rival, it fulfills amateur wildlife or sports needs far better than the A2100 IS.

Street Photography

Discreteness and quick handling are crucial on bustling city streets.

The A2100 IS shines here due to its compact size and light weight, fitting discreetly in coat pockets and allowing stealthy shooting without drawing attention.

The SX520 HS’s bulk makes candid street photography more conspicuous. Its extended zoom is less useful in close quarters, making it awkward to handle without attracting stares.

For low-light urban environments, both have limitations given sensor size and max ISO settings, but the SX520 HS’s higher max ISO (3200 vs. 1600) offers marginally better noise performance.

If portability and quick reaction define your street style, the Canon A2100 IS has an edge.

Macro Photography

Macro demands close focusing, fine detail capture, and stabilization.

Canon’s A2100 IS impresses with a true 1 cm macro focusing range, allowing intimate close-ups of flowers and insects - something the SX520 HS’s spec sheet lists as 0 cm, but practically feels less flexible for extreme close-ups.

Stabilization helps with handheld macro images - both cameras include optical IS, which I found invaluable with handheld subjects in natural light.

However, superior sensor resolution on the SX520 HS hints at better detail rendition at slightly longer macro distances.

If true macro thrills you, the older A2100 IS’s 1 cm focusing capability remains noteworthy.

Night and Astro Photography

Tackling low light and astrophotography requires excellent high ISO handling, long exposure support, and noise control.

The A2100 IS’s native ISO tops at 1600; usable night shots require tripod stabilization and noise reduction that often sacrifices detail. The older CCD sensor amplifies noise, and shutter speeds max out at 15 seconds - enough for some light painting but limiting for deep-sky shots.

The SX520 HS features a 2000 max shutter speed and higher ISO ceiling of 3200 with reduced noise due to BSI-CMOS tech. While it won’t replace dedicated astro cameras, it permits more forgiving handheld night shots and milder noise in starry sky captures.

For any serious night or astro shooter, neither camera matches the performance of larger-sensor cameras, but the SX520 HS provides a better entry point.

Video Capabilities

Both cameras serve basic video needs, but the SX520 HS substantially exceeds the A2100 IS here.

The A2100 IS records only VGA 640x480 video at 30 fps using Motion JPEG - a format that inflates file size and limits editing flexibility.

The SX520 HS upgrades to Full HD 1920x1080 recording at 30 fps via MPEG-4 and H.264 compression, delivering smoother, higher quality footage suitable for casual video storytelling. It also has HDMI output to review footage on larger screens.

Neither camera features microphone or headphone jacks, restricting audio options.

For vloggers or hybrid shooters, the SX520 HS’s video abilities are a significant advantage.

Travel Photography and General Use

Travel photography demands versatility, reliability, and manageable size/weight.

The A2100 IS’s lightweight and small form make it appealing for day trips, museum visits, or casual sightseeing. Its AA batteries mean replacing power is straightforward, especially when overseas without charging facilities. Battery life varies but is generally sufficient for moderate use.

The SX520 HS relies on a rechargeable NB-6LH battery with an official rating around 210 shots per charge - somewhat limiting but typical for superzooms with more power-hungry electronics. The camera’s weighing 441 grams and chunkier body add bulk to travel bags but compensate with spectacular zoom flexibility, video capabilities, and manual features.

Its single SD/SDHC/SDXC card slot is standard, and USB 2.0 data transfer works well enough, but lack of wireless features may irk modern travelers expecting instant sharing.

Professional Applications

Neither camera is designed for professional workflows, but each can fulfill niche roles in constrained budgets.

The A2100 IS is best categorized as a point-and-shoot for casual or documenting needs. It lacks RAW capability, manual exposure modes, or advanced AF systems, limiting pro-level control.

The SX520 HS, offering manual modes, exposure compensation, continuous AF, and higher resolution, can serve as a secondary camera for pros needing a compact telephoto option for quick field shots or reference images.

Both cameras lack robust build quality, weather sealing, or dual card slots. Without RAW, file flexibility and post-processing latitude diminish.

In my testing, image quality and control benefit much from the SX520 HS if a pro-level budget is unavailable, but serious professionals will quickly find their needs unmet.
