Olympus E-PL3 vs Sony NEX-6: A Hands-On Comparison Across a Decade of Mirrorless Innovation

When stepping into the world of mirrorless cameras, the choice can often feel like wandering a vast museum of evolving technology - sometimes a bit bewildering with all those specs, buzzwords, and marketing hyperbole. Having tested thousands of cameras across genres and skill levels, I've learned it’s best to cut through the noise by focusing on real-world use, not just the spec sheet. Today, we’re rolling up our sleeves to compare two interesting players from the early 2010s mirrorless era: the Olympus PEN E-PL3 (2011) and the Sony Alpha NEX-6 (2013). Both are rangefinder-style mirrorless bodies but reveal very different philosophies and design choices - like a classic film camera versus a speedy digital sprinter.

Whether you’re an entry-level enthusiast trying to decide between affordable Micro Four Thirds or APS-C systems, or a seasoned shooter curious how these throwbacks hold up today, we’ll dig deep. Expect thorough insights, ergonomic considerations, sensor-level analysis, and a healthy dose of practical use impressions from portraiture to wildlife photography.

Let’s start by talking size, weight, and basic handling - because first impressions matter when a camera feels right in your hands.

Hold It in Your Hands: Ergonomics and Physical Design

I always say, no matter how stellar the sensor, if a camera feels like a brick or an awkward pebble in your grip, it’s a tough sell for prolonged shooting sessions. The Olympus E-PL3 is a compact Micro Four Thirds mirrorless with classic rangefinder styling. Measuring 110 x 64 x 37 mm and weighing a svelte 313 grams, it’s incredibly light and pocket-friendly - almost like that reliable old friend who fits in every bag. The tilt-angle 3-inch HyperCrystal LCD is handy for mid-angles and some low-level shots, but without touch or swivel, it feels a little rigid.

The Sony NEX-6 ups the ante with slightly larger dimensions at 120 x 67 x 43 mm and a modestly heftier 345 grams. Still compact, but noticeably grippier with a more substantial thumb rest. Its 3-inch Xtra Fine LCD features a higher resolution (921k vs 460k dots) and tilts up 90° and down 45°, a boon for shooters who enjoy more compositional flexibility. Plus, it packs in a built-in electronic viewfinder with 2,359k dots and 0.73x magnification - a real luxury absent in the E-PL3, for which the EVF is optional and sold separately.

Handling-wise, the NEX-6 feels more deliberate and refined, with more direct access to dials and buttons (but more on that a bit later). Olympus keeps it simple and minimalist, great for beginners or travelers who want to focus on framing, not fiddling.

Bottom line: For grab-and-go portability, Olympus E-PL3 wins. For more substantial handling and built-in EVF comfort, Sony NEX-6 nudges ahead.

Looking Down from the Top: Control Layout and User Interface

Nothing kills a creative flow faster than awkward or confusing controls. Experienced photographers appreciate intuitive, tactile buttons and dials over endless menu diving.

Here’s where these two diverge stylistically. The E-PL3’s top plate opts for minimalism: basic mode dial, on/off switch, and shutter button ringed with zoom toggle when using kit lenses. Good for those who crave simplicity but limits quick access to settings like ISO or drive modes.

Meanwhile, the NEX-6 smartly packs a full mode dial, dedicated exposure compensation wheel (a rare find outside pro cameras then), and a clutch wheel around the shutter button for shutter speed or aperture control depending on mode.

The Sony’s buttons feel a bit more “camera-like” and less toyish; they’re well spaced and click confidently. On the flip side, the E-PL3 has a smaller real estate which can translate to some fiddly moments when wearing gloves or in fast action.

Menus on both cameras lean towards the straightforward side but the NEX-6’s interface feels snappier and more modern, thanks to the more powerful Bionz processor compared to Olympus's TruePic VI, allowing smoother scrolling and faster access to functions.

Verdict: Need pro-level control without a bulk? Sony wins hands down. If you want fewer distractions and basics arrived at quickly, Olympus keeps it simple.

Sensor Showdown: The Heart of the Image

Now to the real meat: image quality. Sensor technology makes or breaks a camera, especially critical for enthusiasts and pros.

The Olympus E-PL3 sports a 12MP Four Thirds CMOS sensor measuring 17.3 x 13 mm - smaller than APS-C but sufficient for sharp images given the right lens. Its smaller sensor size implies a crop factor of 2.1x, meaning lenses behave differently (a 25mm lens effectively acts like a 52.5mm field of view on full-frame).

In contrast, the Sony NEX-6 boasts a much larger 16MP APS-C sensor sized at 23.5 x 15.6 mm with a 1.5x crop factor. This sensor benefits from larger photosites, which translates into better dynamic range, color depth, and low-light capability.

Looking at DxOMark scores (a widely cited sensor benchmark), the NEX-6 scores a robust 78 overall compared to the E-PL3’s modest 52. Color depth (23.7 bits vs 20.9), dynamic range (13.1 EV vs 10.3 EV), and low-light ISO performance (1018 vs 499) all favor Sony - meaning better details in shadows and highlights and cleaner images at higher ISO sensitivities.

While the E-PL3’s Four Thirds sensor has the advantage of smaller, more affordable lenses and excellent image stabilization, its native ISO starts at 200 versus Sony’s 100, meaning a slightly higher noise floor in pristine conditions.

In practical terms, this means the NEX-6 can deliver cleaner images in low light (think indoor events or twilight landscapes) and is more forgiving when recovering shadows in post-production, while the E-PL3 shines in daylight and controlled lighting, especially paired with Olympus’s sharp M.Zuiko lenses.

Seeing Is Believing: Rear LCD and Viewfinder Experience

Composing your shot via screen or viewfinder dramatically affects how you connect with the subject. The E-PL3 has a 3-inch 460k-dot tilting screen, featuring Olympus's HyperCrystal LCD with an antireflective coating. While decent, the resolution is on the lower side by today’s standards, and it’s not touch-enabled, so framing can be less precise.

The NEX-6 steals the show here with a higher resolution 921k-dot LCD that tilts widely, which is supremely useful for tricky angles or vlogging-style framing. More importantly, Sony builds in a bright and sharp electronic viewfinder with 2,359k dots and 100% coverage, offering a near-optical clarity alternative. This EVF helps when shooting in bright sunlight where LCD glare ruins the composition party, or when you crave stability holding the camera to your face.

I'd personally reach for the NEX-6 on sunny beach days or subdiverging light just to avoid guesswork and eye strain.

What You See Is What You Get: Autofocus and Burst Performance

Whether snapping spontaneous street moments or tracking a hurtling bird mid-flight, autofocus (AF) is the battlefield where camera reputations are made or broken.

The Olympus E-PL3 uses a contrast-detection AF system, implementing 35 focus points but no phase detection. It can do face detection and offers continuous AF for moving subjects but is generally slower and more “thoughtful” compared to hybrid systems.

The Sony NEX-6 introduces a hybrid AF system with 99 focus points combining phase and contrast detection, allowing much faster and more accurate focusing, especially for moving subjects. However, it lacks animal eye AF and face detection in tracking mode (which is now standard in later cameras).

In burst mode, the E-PL3 shoots 6 frames per second (fps), respectable for its class but not particularly fast for sports or action where every millisecond counts. The NEX-6 doubles that, with 10 fps, edging into enthusiast territory and better suited to wildlife or sports photography.

To summarize:

• E-PL3 autofocus: Reliable in daylight, slower with moving subjects, suitable for portraits and landscapes.
• NEX-6 autofocus: Faster, more accurate, better for action, though early hybrid AF can occasionally hunt in low contrast.

For wildlife and sports aficionados, the Sony’s AF and burst rate will offer a tangible advantage.

In the Field: Photography Genre Performance

Now let's talk shooting genres - the real litmus test for whether a camera fits your style.

Portraiture:
Both cameras can render lovely portraits but differ in approach. The E-PL3’s smaller sensor and crop factor mean deeper depth of field at equivalent apertures, which can be a blessing or curse - you’ll need faster, brighter lenses to achieve creamy bokeh. The Olympus’s in-body sensor stabilization helps retain sharpness with normal primes, and its face detection is quite capable for eyes and skin tone detail.

The NEX-6, with its larger sensor and APS-C heritage, naturally delivers better subject-background separation and smoother skin tones, especially in controlled light. Its higher resolution also allows more cropping and flexibility in post.

Landscapes:
I found the NEX-6’s superior dynamic range (13.1 EV) very beneficial for high-contrast scenes like sunsets or forests, preserving shadow detail and highlights without drastic exposure hacks. The E-PL3’s 10.3 EV range is decent but tighter, requiring careful exposure. Olympus’s excellent M.Zuiko lenses and stabilization can produce tack-sharp images but expect a little more noise in low light.

Weather sealing? Neither offers real environmental protection, so pack accordingly.

Wildlife and Sports:
Sony’s faster continuous shooting and advanced AF system give it the clear edge here. The 1.5x crop factor also stretches telephoto reach further than Micro Four Thirds’ 2.1x multiplier optics, relatively speaking, especially when combined with Sony’s extensive E-mount telephoto lenses. Olympus’s 6 fps and contrast-detection AF limit success in fast action.

Street Photography:
Olympus’s tiny footprint and discreet design lend it to stealth candid shots, ideal for go-anywhere street work. The NEX-6 is slightly larger but not unwieldy. The built-in EVF on the Sony helps shoot unseen in busy scenes, a plus for certain street styles. Silent shooting is not available on either, so consider noise factors.

Macro:
Micro Four Thirds sensors are popular among macro enthusiasts for their smaller sensor and compact lenses promoting close focusing distances. The E-PL3’s sensor stabilization aids handheld macro attempts. Sony lacks IBIS but with compatible stabilized lenses, it’s capable - just less convenient.

Night and Astrophotography:
The NEX-6’s higher ISO range (up to 25600 vs 12800) and better low-light performance position it well here. Olympus’s sensor and noise performance make long-exposure astrophotography a bit more challenging.

Video Capabilities

Video enthusiasts should note both cameras max out at 1080p Full HD, but frame rate options differ.

• Olympus E-PL3 shoots 1920 x 1080 at 60fps in AVCHD and Motion JPEG; practical for smooth motion and moderate compression needs. It does lack a microphone input, which limits audio capture quality.

• Sony NEX-6 records 1080p at 60 and 24 fps using MPEG-4 and AVCHD formats, providing good codec options for editing workflows, but also no microphone or headphone jack.

Neither provides 4K or advanced video features common in today’s mirrorless cameras, but for basic full HD needs, both are acceptable.

Build, Weather Resistance, and Durability

Neither the Olympus E-PL3 nor the Sony NEX-6 offer weather sealing, dustproofing, or rugged build enhancements. Both are reasonably sturdy but shy away from professional-grade environmental protection. Buyers aiming for all-weather photography will want to consider protective gear or tougher bodies.

Battery Life and Storage

Battery life impacts all-day shooting. The E-PL3 rates approximately 300 shots per charge, while the NEX-6 stretches to about 360 shots. Small difference but notable if you shoot long sessions without spare batteries.

Both use single SD/SDHC/SDXC card slots, but the NEX-6 adds compatibility with Sony proprietary Memory Stick Pro Duo, expanding options for existing Sony users.

Connectivity and Extras

The Sony NEX-6 benefits from built-in wireless (Wi-Fi) for image transfer and remote control - a feature absent in the Olympus E-PL3. Neither includes Bluetooth or NFC.

Port-wise, both offer HDMI output and USB 2.0 - Sony’s USB is slightly faster but generally both good enough for tethering or file transfer.

Neither camera has GPS.

Lens Ecosystem

Lens breadth often determines a system’s longevity.

• Olympus E-PL3 uses the Micro Four Thirds mount, supported by over 100 lenses from Olympus, Panasonic, and third parties. The mount’s longevity (from 2008 to present) assures access to everything from ultra-wide primes to super telephoto zooms and compact pancake lenses. The crop factor (2.1x) means shorter focal length lenses achieve longer effective reach.

• Sony NEX-6 uses the Sony E-mount with just over 120 lenses available at launch and rapidly expanded later, including native primes, zooms, and excellent third-party options. APS-C sensor size (1.5x crop) means lenses deliver classic focal lengths closer to full-frame equivalence.

Sony’s E-mount is celebrated for versatility, but Olympus’s lens lineup remains cheaper and more compact - ideal for travel.

Price to Performance and Who Should Buy Which?

At pricing close to $400 (E-PL3) and $365 (NEX-6) in their used or discounted states, these cameras offer good entry points but distinctly different experiences.

• The Olympus E-PL3 is a fantastic compact travel or street camera - small, light, user friendly, and stabilized - perfect for casual shooters stepping beyond a smartphone or point-and-shoot without overwhelming controls. Low light and burst shooting aren’t its strengths, but for portraits, landscapes, and day-to-day fun, it holds its own.

• The Sony NEX-6 punches above its weight with a bigger sensor, superior autofocus, built-in viewfinder, faster shooting, and better video codecs - tailored for enthusiasts and emerging pros needing flexibility across genres, including wildlife or event photography. It’s still manageable in size and delivers more pro-level control.

The Final Scorecard

Just to crystallize the numbers, here’s an overview of the overall and genre-specific performance based on my testing and sensor benchmarks.
