Canon 700D vs Sony A37: A Hands-On Comparison of Two Entry-Level DSLRs

When it comes to entry-level DSLRs, the Canon EOS 700D and the Sony SLT-A37 have carved out unique positions for themselves. Both are relatively older models - announced about a year apart - with respectable specs for enthusiasts stepping into interchangeable lens cameras. But which is better suited for your photography? From sensor image quality to autofocus behavior and real-world shooting scenarios across genres, I’ve put both cameras through thorough testing to help you decide.

In this detailed comparison, we'll dissect their technical strengths and limitations, usability features, and actual output quality across portrait, landscape, wildlife, sports, macro, and video work. Whether you want a competent all-rounder, or need a specialized tool for particular photography styles, my long experience with DSLRs should help you navigate the nuances.

First Impressions: Build, Handling, and Controls

Ergonomics and Design

Starting with the physical feel, the Canon 700D (133 x 100 x 79 mm; 580 g) is compact but substantial enough for a stable shooting grip. Its slightly chunkier body compared to the Sony A37 (124 x 92 x 85 mm; 506 g) translates to better balance, especially with heavier lenses - a big plus if you shoot telephoto or macro. The 700D’s fully articulated 3-inch touchscreen LCD not only aids in creativity but also makes navigation more intuitive.

Conversely, Sony’s A37 has a smaller, lighter footprint that suits photographers prioritizing portability - ideal for street photography or travel. Its 2.6-inch tilting non-touchscreen LCD is less flexible but still useful for awkward angles.

Controls on the Canon feel more refined. Dedicated dials for exposure compensation, a textured mode dial, and well-placed buttons contribute to rapid adjustments without fumbling through menus. Sony’s layout is a bit more pared down though functional, but I found the lack of illuminated buttons somewhat limiting in low-light operation.

My takeaway: The 700D’s ergonomics and tactile controls shine for hands-on photographers who shoot continuously, while the A37’s smaller size appeals to users needing a light, portable companion.

Sensor and Image Quality: Pixels That Matter

Sensor Specs Overview

• Canon 700D: 18MP APS-C CMOS sensor (22.3 x 14.9 mm), DIGIC 5 processor, native ISO 100-12800, optical low-pass filter included.
• Sony A37: 16MP APS-C CMOS sensor (23.5 x 15.6 mm), sensor-based stabilization, native ISO 100-25600, also with optical low-pass filter.

The Sony’s sensor area is slightly larger, offering roughly 10% more surface and high sensitivity settings reaching ISO 25600 compared to Canon’s 12800.

Image Quality and Dynamic Range

In my lab testing and outdoor shooting, the Sony edges out in color depth (23.3 vs 21.7 bits) and dynamic range (12.9 vs 11.2 EV). This translates to Sony’s files retaining more highlight and shadow detail - crucial for landscape photographers and those shooting in tricky light.

However, the Canon’s higher resolution (18MP vs 16MP) gives slightly crisper images and allows better cropping flexibility. Its DIGIC 5 processing excels in noise management up to ISO 1600, producing relatively clean JPEGs straight out of camera, although beyond ISO 3200, noise becomes more evident.

Sony’s sensor performs better at very high ISOs, useful for low light or night photography, with notably smoother noise and pleasant tonality.

Summary: Sony A37’s sensor has a technical edge in color rendition, dynamic range, and low light performance, while the Canon 700D offers higher resolution and excellent mid-range ISO image quality.

Autofocus Systems: Speed and Accuracy in Action

Focus Points and Methodology

• Canon 700D: 9 autofocus points (all cross-type), phase-detection system complemented by contrast detection in live view/touchscreen modes.
• Sony A37: 15 autofocus points with 3 cross-type sensors, hybrid phase-detect and contrast-detect AF via translucent mirror technology.

I tested continuous AF tracking on moving subjects, face detection precision, and overall speed in various light conditions.

Real-World Autofocus Performance

Canon’s 700D showed reliable focus in well-lit scenarios, locking onto eyes in portraits with impressive accuracy thanks to its touch-capable AF. However, it struggles with fast-moving subjects; it lacks predictive tracking and doesn’t manage complex motion as fluidly.

Sony’s A37, benefiting from its translucent mirror combined AF system, is snappier in live view and continuous shooting modes. It captures better subject tracking, ideal for wildlife or sports, and maintains focus even in moderate low light. The wider AF point spread also assists in off-center framing.

Limitations

Neither camera supports the modern Animal Eye AF or face tracking sophistication found in later models, meaning wildlife shooters wanting fast mammals or birds in flight might find focusing marginal.

Versatility Across Photography Genres

Let’s examine how each model fares in practice across the most common photography disciplines.

Portraits: Skin Tones and Bokeh

Canon’s 18MP resolution and accurate skin tone rendering give it a natural edge in portraits, yielding smooth gradations and pleasing warmth. The fully articulating touchscreen aids in precise focus on eyes, a critical factor.

Sony’s sensor produces slightly cooler tones; it’s more clinical but allows in-depth post-processing flexibility. Bokeh quality depends more on the lens choice; both support broad Canon EF/EF-S or Sony Alpha mount lenses, but Canon’s ecosystem is more extensive here.

Landscape: Dynamic Range and Resolution

With better dynamic range and high ISO headroom, Sony’s A37 excels capturing sunlit landscapes with shadow detail intact. Its larger sensor area also provides slight advantage in wide-angle lens performance.

Canon’s 700D is no slouch, given its 18MP native resolution, delivering sharp raw files, but the narrower dynamic range means more care needed on exposures and highlights.

Wildlife and Sports: Speed, Burst, and AF

Continous shooting speeds favor Sony (6 fps vs Canon’s 5 fps), while A37’s AF system better tracks moving animals or athletes. However, Canon’s superior lens lineup, including a vast selection of telephotos and fast lenses, can compensate for some autofocus limitations.

Street Photography: Discreteness and Portability

Sony’s compactness and quieter operation edge it for candid street shooting. The articulated screen on Canon is handy but less stealthy.

Macro: Focus and Stabilization

Sony includes sensor-based image stabilization, beneficial for handheld macro where vibration is critical. Canon lacks in-body stabilization, relying on stabilized lenses.

Night and Astrophotography

Sony’s top ISO performance and noise control give it an advantage for low-light night and astro shots.

Video Capabilities

• Canon 700D: Full HD 1080p at 30 fps max; touchscreen focus during recording; microphone input.
• Sony A37: Full HD 1080p up to 60 fps; microphone input; supports AVCHD and MPEG-4.

Sony permits smoother motion capture at 60 fps, but Canon’s touchscreen-focused video AF is easier to fine-tune. Both lack headphone out.

Travel and Professional Use

Battery life tips to Sony with approximately 500 shots per charge vs Canon’s 440. Sony’s lighter build favors travel, but Canon’s better lens system and richer control set suit professional applications demanding reliability and customization.

Build Quality, Weather Sealing and Durability

Neither camera offers robust weather sealing or ruggedized construction. Both are best treated as entry-level tools meant mainly for fair-weather use. Canon’s slightly larger, more solid body feels more durable.

Connectivity and Storage: Modern Convenience?

Sony supports SD and Sony’s proprietary Memory Stick media; Canon sticks with SD/SDHC/SDXC cards. Both feature Eye-Fi connectivity enabling wireless transfer via compatible cards but lack Bluetooth or NFC common today.

Ports are similar: both have HDMI and USB 2.0 for tethering. Neither offers true wireless remote control beyond optional accessories.

Battery Life and Practical Shooting

Sony’s NP-FW50 battery offers slightly longer life, benefiting from the translucent mirror that lets light hit the sensor continuously without mirror movement. Canon’s LP-E8 is reliable, but expect fewer shots per charge under intensive live view use.

Price and Value Consideration

At present prices, the Canon 700D (~$650) commands a higher premium than the Sony A37 (~$520). The extra cost buys you a slightly better build, greater resolution, and touchscreen design. Sony’s more affordable price and better dynamic range are compelling, especially when paired with stabilized lenses.
