Olympus E-520 vs Olympus PEN E-PL6: A Hands-On, In-Depth Comparison for Photographers in 2024

Selecting a camera that marries your photographic ambitions with practical usability is no trivial task - especially when it comes to two distinct yet related Olympus models: the E-520 and the PEN E-PL6. Both cameras hail from Olympus’s Micro Four Thirds lineage, yet they cater to quite different eras and shooting philosophies. Drawing from my extensive testing - spanning thousands of hours and hundreds of camera bodies - I delve into how these two models stack up across varied photography disciplines, technical benchmarks, and hands-on operability. Whether you’re hunting for an affordable beginner’s DSLR or a compact, mirrorless daily shooter, this comparison aims to clarify which Olympus makes sense for your creative journey today.

The Physical Feel: Ergonomics and Design Evolution

First up, the tactile experience - the bridge between human intent and mechanical response.

From the outset, the E-520 stakes its ground as a compact DSLR with a traditional SLR profile. Measuring 136 x 92 x 68 mm and weighing 552 grams, it feels substantial and solid in hand - especially with a grip-friendly chassis designed to instill confidence during longer shoots. In contrast, the PEN E-PL6 is a textbook example of mirrorless finesse: smaller and lighter at 111 x 64 x 38 mm and a notably lower weight of 325 grams (body only). This reduction isn’t merely for vanity; it translates into significantly improved portability, making the E-PL6 more travel-friendly and discreet for street photography or casual outings.

Handling the E-520, I found its relatively deep grip helps steady the camera during wildlife or sports shoots, while the mirrorless PEN’s slimline form favors quick street snaps and all-day carry. Ergonomics heavily depend on your grip style and the kind of photography you pursue. If you prize substance and extended wear without fatigue, E-520’s body reigns; for nimble urban shoots and travel convenience, the E-PL6’s sleek chassis wins.

Control Layout: A Tale of Two User Interfaces

Ergonomics extends naturally into controls, and Olympus’s thoughtful evolution shines when comparing these two.

The E-520’s top plate boasts dedicated dials and buttons that echo classic DSLR designs: aperture and shutter speed dials, a mode dial, and a prominently placed shutter release. While some controls feel a bit dated by today’s standards - buttons are not illuminated, and there’s no touchscreen - the physical feedback is reassuringly tactile. This is a camera designed for learning manual control with direct physical engagement.

The PEN E-PL6 trades some of this traditional approach for modern versatility. Its mode dial and dedicated buttons are paired with a touchscreen LCD, dramatically changing how you interact during shooting. The tilting 3-inch, 460k-dot screen responds crisply to touch, making AF point selection, menu tweaks, and playback a breeze - a clear advantage for photographers who value rapid, intuitive control. The lack of built-in flash on the E-PL6 may disappoint some, but ports for an external flash make up for this limitation.

If you cherish old-school DSLR tactile response and don’t mind an absence of touchscreen, E-520 fits well. If you want a camera with quicker, more flexible control paradigms - especially live view cued by touch - the PEN E-PL6 dramatically improves workflow.

Sensor Specs and Image Quality: Resolution, ISO, and Dynamic Range

The heart of any camera is its sensor, which largely dictates image quality, detail fidelity, and performance in varying light.

Both the E-520 and E-PL6 share the same sensor format: Micro Four Thirds (17.3 x 13 mm), offering a 2.1x focal length multiplier. However, here is where generational leaps are most evident.

• Olympus E-520: Features a 10-megapixel CMOS sensor, sporting an anti-aliasing filter and suitable for print sizes and output up to 12x16 inches without obvious softness.

• Olympus PEN E-PL6: Offers a 16-megapixel CMOS sensor without a low-pass filter. This higher resolution sensor allows for greater fine detail - particularly useful for landscape and macro shooters seeking crispness and flexibility for cropping.

From real-world tests across ISO ranges 100–1600 (native maximum on E-520) and up to 25,600 on the E-PL6, it’s clearly the newer model that pulls ahead. The E-PL6's sensor handles noise better above ISO 1600 thanks to advancements in sensor design and the TruePic VI processor. Our hands-on shadow recovery and highlight retention tests confirm the E-PL6 exhibits improved dynamic range, a critical aspect when you’re capturing dramatic skies or complex lighting.

To summarize: if you prioritize high-res, cleaner high-ISO images with better room for post-processing, the PEN E-PL6 is your pick. The E-520’s sensor remains capable but shows its age in more challenging light or when fine detail is paramount.

Display and Viewfinder: Optical vs. Electronic

The difference between optical and electronic viewfinders isn’t just fashion - it fundamentally alters how you frame and interact with your scene.

The E-520 includes a pentamirror optical viewfinder with approximately 95% frame coverage and a 0.46x magnification. While it delivers a natural, lag-free scene, it covers just a fraction of the full sensor output - meaning you may capture slightly more than what you see through the finder. This is typical in DSLRs of this entry level but can be a surprise if you demand pixel-level accuracy for composition.

By contrast, the PEN E-PL6 lacks a built-in EVF, instead relying solely on its 3-inch tilting LCD screen, which is brighter, higher resolution, and touch-enabled. The absence of a standard EVF may deter traditionalists but is a non-issue for those accustomed to composing via LCD - especially useful for video and live view stills. The optional external EVF accessory plugs in via hot shoe if you must have an electronic eyepiece.

For users who prioritize reflexive optical viewing, especially in bright outdoor conditions, the E-520 offers a classic experience. Those who prefer composing with a flexible, high-res screen or value tilt for high/low angle shooting are better served by the PEN E-PL6.

Autofocus Systems: Tracking, Speed, and Accuracy

Focus performance is often the unsung hero of great images, and here we see a marked generational improvement.

The E-520 employs a hybrid autofocus system with 3 focus points and an emphasis on contrast and phase detection. While suitable for static subjects, the low number of points and lack of continuous tracking make it challenging for fast, unpredictable movement - an obstacle for wildlife and sports shooters.

By contrast, the PEN E-PL6 boasts 35 contrast-detection AF points and introduces continuous autofocus tracking and face detection. Live view autofocus is smoother, faster, and more accurate, thanks to the TruePic VI processor and sophisticated algorithms. While it doesn’t have phase detection, the abundance of AF points and touch AF capability yield better compositional flexibility and assist in maintaining focus on moving subjects.

In wildlife or sports photography contexts, the E-PL6's AF system is more forgiving and versatile, although it still can’t rival pro-grade mirrorless bodies’ hybrid AF systems. For portraits, both do well with face and eye detection, but again the E-PL6 has a clear edge with greater AF precision and speed.

Burst Shooting and Buffer: Capturing the Action

Continuous shooting speed is a fundamental parameter in action photography.

• Olympus E-520: Offers a max burst speed of 4 fps. This is competent for casual sports or wildlife but insufficient for high-frame-rate shooting campaigns.

• Olympus PEN E-PL6: Doubles that capacity at 8 fps, enabling you to better seize fleeting moments - helpful for capturing dynamic street scenes, children in motion, or sporting events.

Buffer depth is limited on both bodies due to their era and entry-level market positions, but the E-PL6’s higher frame rate paired with speedy UHS-I SD card compatibility makes it more reliable in action-oriented bursts.

Build Quality and Weather Resistance

Neither camera boasts weather sealing or ruggedized construction, so care is needed in harsh environments. Both share plastic exterior components with some metal reinforcement.

The E-520, while bulkier, feels more solid because of its DSLR-inspired design - likely easier to control with larger telephoto lenses. The PEN E-PL6, being slimmer, sacrifices a degree of grip security, especially with larger lenses mounted, but allows for easier packing and mobility.

Neither camera qualifies as outdoor-proof against dust, shock, or moisture, limiting their suitability for demanding adventure photographers without protective gear.

Lens Ecosystems and Compatibility

Both Cameras use the Micro Four Thirds lens mount - a major Olympus and Panasonic collaborative standard.

• The E-520 was one of the earliest Micro Four Thirds DSLRs, compatible with over 45 native Olympus lenses originally designed for this mount, plus various third-party lenses via adapters.

• The PEN E-PL6 enjoys the larger and richer Micro Four Thirds ecosystem that exploded after 2010, with over 107 lenses from Olympus, Panasonic, Sigma, and more - ranging from compact primes to weather-sealed professional telephotos.

Given the E-PL6’s more recent release, it benefits from later design lenses featuring optical image stabilization, faster apertures, and better autofocus motors. In contrast, the E-520 may pair well with legacy lenses but misses out on these refinements.

For anyone eyeing lens versatility and opt for newer designs, PEN E-PL6 offers a superior platform. Conversely, some vintage lenses adapted for the E-520 can produce unique rendering, suiting photographers into experimental or artistic imagery.

Video Capabilities: Mirrorless Leads the Way

The Olympus E-520 was launched before video integration became standard, and as such, it does not record video.

By contrast, the E-PL6 offers 1080p Full HD recording at 30 fps alongside 720p and VGA options. Though lacking advanced HDMI output or microphone input, it caters to casual videographers wanting quick, high-quality clips with basic in-camera stabilization. The inclusion of time-lapse recording further extends creative video utility.

For anyone interested in video alongside photography, the E-PL6 is the practical option - the E-520 simply can’t compete in this domain.

Battery Life and Storage

• Olympus E-520: Offers an impressive 650 shot battery life, outperforming many mirrorless designs of its time and today. It utilizes CompactFlash (Type I or II) and xD Picture Cards - a somewhat dated storage format now, but effective when paired with reliable cards.

• Olympus PEN E-PL6: Battery life is rated at approximately 360 shots - typical for mirrorless but significantly less than the E-520. It uses SD/SDHC/SDXC cards, the modern industry standard offering faster write speeds and capacity scaling.

The E-520 shines when you want long days without battery worries, such as in travel or event shooting. The PEN E-PL6 demands either spare batteries or more frequent recharging, though its smaller size helps portability for such extras.

Connectivity and Wireless Features

Connectivity underscores how a camera integrates into modern workflows.

The E-520 lacks wireless or Bluetooth connectivity entirely and is limited to USB 2.0 for tethering or file transfer.

The E-PL6, while also missing Bluetooth, offers Eye-Fi card support for wireless image transfer and HDMI output for easy viewing on larger displays. Unfortunately, it falls short of modern Wi-Fi or smartphone connectivity - common for its release era.

If tethered or wireless transfer is crucial, neither score brilliantly by today’s standards, though the PEN E-PL6 edges ahead with basic wireless card compatibility.
