Canon 500D vs Sony A57: The Definitive Entry-Level DSLR Showdown

In the crowded realm of entry-level DSLRs, two cameras stand out as intriguing choices for photographers keen to balance performance, price, and feature sets: the Canon EOS 500D (also known as the Rebel T1i or Kiss X3), released in 2009, and Sony’s SLT-A57, introduced three years later in 2012. With the Canon 500D marking a high point in Canon’s early DSLR lineup, and Sony’s A57 showcasing a bold approach with their translucent mirror technology, these two models offer a fascinating study in contrasting philosophies within the same mirrorless-adjacent segment.

Having spent extensive hands-on time with both cameras - examining them in the studio and out in the field across a broad spectrum of photographic disciplines - this comparison aims to unpack everything you need to know before committing one way or the other. Because while these two share the entry-level moniker, the differences in image quality, autofocus, ergonomics, video performance, and usability are substantial. Let’s dive deep into the heart of each camera and see which reigns supreme for your specific needs.

First Impressions: Handling and Build Quality

The very first interaction with a camera often sets the tone for the shooting experience ahead, and here the Canon 500D and Sony A57 take quite different paths.

Canon 500D: The Canon’s traditional DSLR body is compact and light, weighing in at just 520 grams with dimensions of 129x98x62 mm. It has a classic SLR shape, familiar to those with Canon experience, and fits nicely in average-sized hands. The footprint is comfortable for extended use, though the plastic construction feels somewhat less refined than higher-tier models. The pentamirror optical viewfinder offers 95% frame coverage, a slight drawback when trying to be precise with composition but common in entry-level DSLRs.

Sony A57: The Sony, meanwhile, tips the scales at 618 grams with slightly larger dimensions (132x98x81 mm), reflecting a sturdier, heftier build. Its use of an electronic viewfinder (EVF) with full 100% coverage and 0.7x magnification immediately sets it apart ergonomically - offering a much more accurate framing experience. The fully articulated 3-inch screen with “Xtra Fine TFT drive and TruBlack technology” is a boon for waist-level shooting and video work. It’s notably more flexible for creative angles and live monitoring, although Sony’s design does place more mass in your hands, which some may find less portable.

When laid side-by-side, the Canon is the smaller and lighter camera - more pocketable and less intrusive in street settings - while the Sony offers a more robust, versatile interface with arguably more premium touches befitting later technology advancements.

Sensor and Image Quality: The Heart of the Matter

Both cameras employ APS-C CMOS sensors, but the details reveal meaningful distinctions that impact image fidelity for various genres, from portrait to landscape.

Canon 500D: Sporting a 15-megapixel sensor sized 22.3 x 14.9 mm, the 500D was a significant upgrade over its predecessor. Canon’s DIGIC 4 processor delivers clean colors and a respectable dynamic range of 11.5 EV (measured via DxO Mark). Color depth clocks in at 21.7 bits, which is excellent for an entry-level DSLR. The sensor features a classic Bayer array with an antialiasing filter, slightly softening fine detail but reducing moiré artifacts.

Sony A57: Sony ups the resolution to 16 megapixels on a slightly larger 23.5 x 15.6 mm sensor, equating to an area roughly 10% bigger (366.6mm² vs 332.3mm² on Canon). This slight physical sensor advantage, combined with no optical low-pass filter versions prevalent in Sony’s later models, yields a higher dynamic range of 13 EV and a superior color depth of 23.4 bits, offering richer hues and finer tonal gradations. The maximum native ISO extends to 16,000 (boostable to 25,600), compared to Canon’s max native ISO of 3200 (boost to 12,800), giving Sony considerable leverage in low-light.

Our experience with both cameras across a variety of lighting conditions bore this out - the Sony delivered cleaner shadow details and greater highlight retention, especially in high contrast landscapes and night scenes.

Autofocus: Speed, Accuracy, and Tracking

Autofocus performance can make or break fast-paced shooting - particularly wildlife, sports, and event photography.

Canon 500D: Utilizing a traditional phase-detection AF system with 9 focus points, it includes face detection but lacks advanced subject tracking. Single-shot AF is reliable and generally accurate for static subjects and portraits. Continuous AF can be sluggish, tipping the scales at about 3 frames per second (fps), suitable for casual bursts but insufficient for fast action work.

Sony A57: The A57’s highlight is its hybrid autofocus that combines 15 phase-detection AF points (3 cross-type) with sensor-based contrast detection, enabling faster, more accurate focusing and tracking. This, paired with an impressive 12 fps burst mode, makes the Sony very attractive to sports or wildlife shooters on a budget. Live view AF is notably smoother and faster here than on the Canon.

During wildlife trials, the Sony’s autofocus better locked onto erratic bird flight and running animals, whereas the Canon occasionally hunted or missed shots in challenging light or movement.

Viewfinder and LCD: Directing Your Creativity

Your viewfinder and rear display are primary interfaces that shape your composition and review workflow.

Canon 500D: Has a traditional optical pentamirror viewfinder, delivering a natural, lag-free view with 95% coverage and 0.55x magnification. It feels a little small and dark compared to modern cameras. The fixed 3-inch TFT LCD with 920k dots is sharp and bright but limited for flexible shooting positions.

Sony A57: The electronic viewfinder, with 100% coverage and a generous 1440-dot resolution, brings a live histogram, exposure preview, and real-time white balance effect into the viewfinder - features absent on the Canon. Sony’s fully articulated 3.0-inch LCD with 921k dots and TruBlack tech allows for flattering outdoor visibility and versatile angles, greatly aiding video and macro work.

For street photographers or anyone who shoots candidly in low light, the Canon’s optical viewfinder remains superior in clarity and laglessness, but the Sony’s EVF provides imaginative new tools for composing with precision.

Image Samples: Real-World Results

Of course, specs only tell part of the story - producing real images under varying conditions provides a deeper evaluation.

Here, portraits from the Canon 500D show warm, natural skin tones with pleasant bokeh from EF-S lenses, thanks to its 1.6x crop factor and compatible optics. Colors are slightly saturated but balanced, faithful to typical Canon rendering.

Sony’s A57 images, however, offer finer detail resolution and a wider dynamic range. Landscape shots exhibit better shadow detail and more subtle gradations, reflecting sensor gains. In low light urban scenes, the Sony maintains noise control better at ISO 1600 and above, while Canon excelling in shutter lag and immediacy.

Both cameras deliver JPEGs and full raw files, allowing enthusiasts to extract maximum quality via editing.

Video Capabilities: Moving Pictures Matter

If you’re stepping into multimedia creation alongside stills, your camera’s video prowess becomes a major factor.

Canon 500D: Records full HD 1080p video, but at a limited 20 frames per second. Its H.264 codec compresses files efficiently, but video footage can feel choppy and lacks smooth panning potential. Coding constraints and the absence of microphone input limit sound quality and input control. The fixed LCD and lack of touchscreen make manual focus a bit cumbersome.

Sony A57: Sony’s video capability is a distinct upgrade, recording full HD 1080p at smooth 60p or cinematic 24p frame rates using AVCHD and MPEG-4 codecs. The inclusion of a mic input allows better audio capture, a crucial advantage for vloggers and event filmmakers. The fully articulated screen combined with Sony’s built-in sensor-shift image stabilization (on the sensor itself) makes handheld video more stable.

For hybrid shooters prioritizing video, Sony’s A57 undoubtedly outpaces Canon’s earlier generation 500D.

Battery Life and Storage: Keeping You Going

Long shoots demand reliability in power and ample media support.

Canon 500D: Uses the LP-E5 battery rated for about 440 shots per charge, which is decent but modest by modern standards. It supports SD/SDHC memory cards but no SDXC. The single card slot and older USB 2.0 interface limit transfer speeds.

Sony A57: The NP-FM500H lithium-ion battery extends endurance to roughly 550 shots per charge. Additionally, Sony’s multi-format card reader caters to SD, SDHC, SDXC, and Memory Stick Pro Duo/Pro-HG Duo cards, diversifying storage options. USB 2.0 remains the transfer interface, so no speed advantage there.

Sony’s enhanced battery life adds confidence for travel and events, although keep in mind the EVF can demand higher power draw than an optical viewfinder.

Lens Ecosystem and Compatibility

No camera body is complete without its lenses - so how do the supporting line-ups stack up?

Canon 500D: Fits into the well-established Canon EF and EF-S mount system, which is one of the broadest camera lens ecosystems globally, with 326 compatible options including top-tier L-series glass. This means unobstructed access to high-quality primes and zooms across all focal lengths, ideal for portrait, macro, wildlife, and landscape demands.

Sony A57: Uses the Sony/Minolta Alpha mount with about 143 compatible lenses, a much smaller but steadily growing collection. Sony did make leaps with recent adaptor tech, but native lens choices for specialized needs like macro or telephoto are more limited compared to Canon’s vast lineup.

For a photographer craving choice and long-term lens investment, Canon’s system remains superior.
