Whether your focus is portraits, landscapes, wildlife, or travel photography, read on for a comprehensive, impartial assessment.

In the Hand: Size, Build, and Ergonomics

Before diving into pixels and specs, how a camera feels in your hand is paramount. This shapes your shooting experience subtly but profoundly over hours of fieldwork.

The Canon T6 boasts a compact yet comfortable DSLR body measuring 129x101x78 mm and weighing around 485 grams without a lens. Olympus’s E-520 is slightly larger in footprint (136x92x68 mm) and a bit heavier at 552 grams. Both cameras utilize plastic construction typical of entry-level models, with no weather sealing to speak of.

Ergonomically, the Canon’s deeper grip facilitates a more secure hold, especially with larger lenses attached. The T6 also features a more traditional DSLR form factor, whereas the E-520’s design leans subtly toward compactness, partly due to its Four Thirds system heritage.

Handling wise, I found the T6's shutter button placement and mode dial more intuitive during extended shooting sessions. The Olympus provides a slightly shallower grip, which might benefit those with smaller hands, but its control layout feels marginally cramped in comparison.

Command Central: Controls and Interface Layout

Easy access to key controls matters more than ever when moments are fleeting.

The Canon T6 sports a straightforward top layout featuring a dedicated mode dial, shutter release, power switch, and access to exposure compensation - all standard fare for DSLRs aiming to balance ease of use and quick adjustments.

Olympus E-520’s top panel is less busy, lacking a physical power switch (push button instead), but incorporating a small monochrome info LCD - a carryover from higher-end models of its day. Unfortunately, its control arrangement is somewhat dated, requiring more menu diving for settings that the Canon places physically at your fingertips.

Both employ fixed, non-touch rear screens (more on screens below), but the T6’s interface benefits from Canon’s well-evolved menu system, which is more beginner-friendly than Olympus’s older design paradigm.

Sensor Size and Image Quality: The Core of Photography

The heart of any camera is its sensor, and here lies a critical difference in design philosophies.

The Canon T6 uses an 18-megapixel APS-C CMOS sensor sized at 22.3 x 14.9 mm, yielding approximately 332 mm² of surface area. This is fairly standard in entry-level DSLRs and offers a good balance of resolution and noise performance. The sensor incorporates an anti-aliasing filter, which helps minimize moiré at the expense of some microcontrast.

The Olympus E-520 employs a Four Thirds sensor, significantly smaller at 17.3 x 13 mm (about 225 mm²) with 10 megapixels resolution. The smaller sensor also means a higher crop factor of 2.1x relative to full frame, versus the Canon’s 1.6x.

In side-by-side testing under controlled lighting, the Canon’s APS-C sensor delivered richer tonal gradation and superior dynamic range (~11.7 EV vs 10.4 EV from DxOMark testing) which translates into more latitude for recovering shadow and highlight details in post-processing.

Low light performance also favors the T6. Its sensor can shoot natively up to ISO 6400 (expanded 12800), while the E-520 tops out at ISO 1600. Canon’s DIGIC 4+ processor imposes notable noise reduction without overly smudging fine details, yielding cleaner images at higher ISOs.

Color depth, a subtle yet vital aspect for portrait and studio photographers, also tips toward Canon’s sensor with a DxO mark of 22.0 bits versus Olympus’s 21.4 bits, enabling more accurate skin tone reproduction when combined with Canon's renowned color science.

User Interface: Screen and Viewfinder

DSLR users often toggle between optical viewfinders and LCD screens depending on shooting conditions.

The Canon T6 features a 3.0-inch fixed LCD with 920k-dot resolution - a modest but serviceable display for framing and reviewing images. Olympus’s E-520 lags behind with a smaller 2.7-inch screen at just 230k dots, which impacts the clarity of menus and playback zoom.

Both cameras use optical pentamirror viewfinders with roughly 95% frame coverage and similar magnification (Canon 0.5x, Olympus 0.46x). The Canon's optical viewfinder offers slightly brighter and crisper compositions, which facilitates manual focusing and accurate framing in bright daylight.

Neither camera offers touchscreen capabilities, which is unsurprising given their age and price brackets. Both provide Live View for composing on the LCD, but Canon’s Live View autofocus is marginally faster and more reliable, a consequence of newer contrast-detection hybrid systems.

Autofocus Systems: Speed and Accuracy Where It Counts

Autofocus is mission critical for capturing fleeting moments, especially in action, wildlife, or candid genres.

The Canon T6 uses a 9-point phase-detection AF system with all points being standard cross-type focus points, which aids in better focus acquisition under varied lighting and subject contrast. It supports Face Detection autofocus and basic eye detection in Live View mode.

Olympus’s E-520 features a more modest 3-point AF system (non-cross-type), reflecting its earlier-generation autofocus technology. This setup is adequate for static subjects but struggles with tracking moving targets or focusing in low light.

In field tests with moving wildlife and street subjects, the Canon’s autofocus was predictably quicker and more consistent, delivering a higher keeper rate. The T6’s autofocus tracking, while not on par with enthusiast-grade cameras, remains competent for beginner wildlife photographers.

Burst Rates and Buffer Performance

For sports and wildlife shooters, frames per second (fps) and buffer depth can mean life or death for capturing decisive moments.

The Canon T6 can shoot at 3.0 fps continuous, which is modest but usable for casual sports. Its buffer holds about 6 RAW frames before slowing. The Olympus E-520 edges out slightly with 4.0 fps continuous, though its 10-megapixel files are smaller, so the buffer size impact is less constrained.

That said, raw buffer depths and burst performance on both cameras restrict prolonged shooting of fast action, so neither camera would satisfy the demands of professional sports shooters but serve entry-level needs.

Lens Ecosystem and Compatibility

A camera is only as good as the glass available for it.

The Canon EOS T6 belongs to the vast EF and EF-S lens lineup, boasting over 320 native lenses covering every focal length and specialty from fisheye to tilt-shift. Investing in Canon’s ecosystem offers flexibility for all photographic styles and budgets.

Olympus’s E-520 uses the 4/3 mount lenses, a system gradually superseded by Micro Four Thirds (MFT). The native lens selection is comparatively sparse (around 45 lenses) and mostly older legacy designs. Additionally, the smaller sensor and greater crop factor affect framing and depth of field characteristics, particularly noticeable in telephoto and wide-angle ranges.

From a practical standpoint, Canon’s DSLR format offers more future-proofing and creativity through lens options.

Image Stabilization and Handling in Low Light

While the Olympus E-520 offers sensor-based image stabilization - a notable feature ahead of its time - this can compensate modestly for camera shake, especially in low light or macro shooting.

The Canon T6 lacks in-body stabilization but benefits from the extensive range of Canon lenses featuring their own IS systems, which often provide superior stabilization performance.

Testing indoors at slow shutter speeds showed Olympus producing steadier handheld shots at 1/10s than the Canon body alone without IS lenses. However, pairing the T6 with Canon IS lenses evens this advantage quickly.

Video Capabilities: An Evolving Necessity

In 2024, hybrid photo-video capability is a must-consider feature for many creatives.

Canon’s T6 shoots Full HD 1080p video at up to 30 fps, supporting H.264 compression - a standard offering for entry-level cameras in 2016. It also supports 720p at 60 fps for smoother motion and offers an HDMI output.

Conversely, the Olympus E-520 does not provide video recording features, a significant drawback for multimedia versatility.

Neither camera includes microphone or headphone jacks, limiting audio control for dedicated videographers.

Connectivity and Storage

The Canon T6 includes built-in Wi-Fi and NFC, enabling quick wireless image transfer and remote control - a boon for social media sharers and on-the-go photographers. Olympus, reflecting its era, lacks any wireless connectivity options.

However, the E-520 supports Compact Flash and xD Picture Cards, while the T6 uses the ubiquitous SD/SDHC/SDXC card formats, simplifying media purchasing and compatibility.

Battery Life and Storage Options

The E-520 impresses with a rated 650 shots per charge versus the Canon’s 500. This difference may arise from the Olympus’s older, less power-hungry sensor and lack of wireless features.

Both cameras use proprietary lithium-ion packs with a single slot, which is typical for this class.

I found both cameras reliable for day-long shooting but recommend carrying at least one spare battery for extended sessions, especially when using Live View or video on the T6.

Environmental Resistance and Durability

Neither camera incorporates weather sealing or ruggedization, so users should exercise caution shooting in challenging weather or dusty environments.

Build quality is typical of entry-level DSLRs, favoring portability and affordability over robust protection.
