Olympus E-520 vs Panasonic Lumix DMC-G6: An Expert Hands-On Comparison

Choosing between cameras that span different styles and generations is often like pitting an old favorite against a spirited up-and-comer. That’s exactly the case when comparing the Olympus E-520, a classic compact DSLR from the late 2000s, against the Panasonic Lumix DMC-G6, a mirrorless entry-level sensation launched five years later. Both share the Micro Four Thirds sensor size, but technology, ergonomics, and use cases have evolved dramatically in that interval.

Having put thousands of frames through more cameras than I can count, I’m here to tell you what these two cameras truly bring to the table - where each excels, stumbles, and for whom they might still make sense today. We’ll walk through the technical chops, day-to-day handling, image quality, and suitability across major photography slots like portraits, landscapes, wildlife, and more.

And to keep things lively, I’ve embedded relevant images to show you what I’m seeing and feeling in the field. So, grab your metaphorical lens cap and let’s dive in.

Getting Physical: Size and Ergonomics Showdown

Let’s start by talking about what you hold - something extremely important that is often overlooked by specs alone.

The Olympus E-520 is noticeably chunkier, weighing 552 grams with dimensions roughly 136 x 92 x 68 mm. This DSLR heft is paired with a solid grip but modest control real estate, leaning on a compact SLR design. Its build isn’t heavy-duty - no weather sealing here - but it feels reassuringly sturdy for its era.

On the flip side, the Panasonic G6 drops nearly 30% of that weight at a sleek 390 grams, packing into a slightly smaller 122 x 85 x 71 mm frame. Its “SLR-style” mirrorless body feels way more portable, especially with the removal of the DSLR’s mirror box. This is a camera designed to slip easily into travel bags or hang comfortably at your side during long street sessions.

Ergonomics-wise, the G6 has a deeper thumb rest and more sculpted grip, lending better one-handed stability. It also sports more external dials and buttons that invite quick adjustments - a real boon when you’re chasing decisive moments or tweaking exposure on the fly.

Comparing top layouts next will underscore these points.

The E-520’s top panel is pretty straightforward but a bit sparse with control clubs for your thumbs and fingers. It has the standard mode dial and shutter speed dials but lacks dual wheels or customizable buttons. The G6 shines here with a more modern control layout: dedicated exposure compensation dial, dual control dials, and an accessible mode dial. This design empowers quicker changes without diving into menus, ideal for active shooting.

Bottom line: For whoever values lighter gear and fluid ergonomic handling - especially for travel and street photography - the Panasonic G6 holds the edge. The Olympus E-520 appeals more to those who want a traditional DSLR shape and heft that feels substantial in the hand.

Under the Hood: Sensor and Image Quality Breakdown

Both cameras use a Micro Four Thirds sensor, measuring 17.3 x 13 mm, but that’s where the similarities end in terms of tech and resultant image quality.

• Olympus E-520: Features a 10MP CMOS sensor with a modest DxO overall score of 55, color depth at 21.4 bits, dynamic range around 10.4 EV stops, and a low-light ISO capability peaking near 548. Sensitivity tops out at ISO 1600 natively. There’s an optical low-pass (anti-aliasing) filter, which slightly softens images, aiming to control moiré.

• Panasonic G6: Steps up to a 16MP CMOS sensor with excellent DxO metrics of 61 overall, color depth of 21.3 bits (comparable), dynamic range stretching to 11.5 EV stops, and greater low-light strength with an ISO low-light score of 639. ISO sensitivity climbs dramatically to 25600 native max, allowing much more flexibility handheld or in darker scenes.

Even though the sensor sizes are identical, Panasonic’s newer sensor technology and image processor deliver markedly better resolution, dynamic range, and low-light prowess. This advantage translates into crisper, cleaner files with greater tonal latitude, especially beneficial in landscape and night photography scenarios where every stop counts.

Sensor resolution also impacts print sizes, cropping flexibility, and fine detail capture for macro work.

Viewfinders, Screens, and Interface: What You See Is What You Get

How you compose and check exposure matters hugely, so here’s how these contenders stack up visually.

The Olympus E-520 sticks to a fixed 2.7-inch, low-resolution (230k dot) LCD screen - not forgiving for critical focus evaluation or touch input (it has none). The optical pentamirror viewfinder covers 95% of the frame with 0.46x magnification, delivering a traditional DSLR shooting experience.

In contrast, Panasonic G6 offers a 3-inch fully articulating touchscreen LCD at much sharper 1,036k dot resolution. This means composing from tricky angles, touch focusing, and navigating menus is smoother and more intuitive. Its electronic viewfinder is a beauty, too, with 100% frame coverage and crisp 1,440k dot resolution at 0.7x magnification, enabling more precise framing and instant feedback on exposure and depth of field.

For those who rely heavily on LCD or EVF for composition - especially video shooters - the G6 is a clear winner, offering modern convenience and accuracy. The E-520’s optical viewfinder is charming but limited by its small coverage and lower magnification.

Autofocus and Shooting Performance: Catching Your Moment

Autofocus is where technology visibly evolved between these two cameras, and it’s crucial to assess if you’re shooting moving subjects or events.

The E-520’s autofocus system is basic but respectable for an entry-level DSLR of its time. It covers 3 AF points and combines phase and contrast detection. However, it lacks continuous tracking - meaning fast-moving subjects are harder to pin down. Burst speed maxes out at 4 frames per second, decent but modest.

Panasonic G6 offers a sophisticated 23-point contrast detection system with subject tracking capabilities, enhancing autofocus accuracy even with erratic movements. With 7fps burst shooting, it’s twice as fast - a boon in wildlife and sports scenarios.

The G6’s contrast detect AF combined with touch screen AF is an excellent combo for quickly selecting focus zones in live view or video. The E-520 lacks touch AF entirely.

Exploring Photography Genres: How Each Camera Fits Your Style

Now, let’s apply these specs to real-world shooting genres.

Portrait Photos: Skin Tones, Bokeh, and Eye Detection

Portraiture demands gentle skin tone rendition, creamy background separation, and accurate focus on eyes.

• Olympus E-520: The 10MP sensor yields decent image quality, but the smaller resolution limits cropping freedom in critical portraits. The 3 AF points and face detection help, but without eye detection, pinpointing focus on the iris can be hit or miss. Sensor-based image stabilization helps hand-held portraits stay sharp.

• Panasonic G6: Thanks to 16MP resolution, you get more detailed captures with better dynamic range preserving subtle facial gradations. The 23-point AF system with face detection (though no specific eye AF) does a better job at locking focus on faces. Live view with touch focus speeds workflow.

Regarding bokeh, both cameras have the Micro Four Thirds crop factor of 2.1x, making shallow depth of field slightly more challenging than full frame. The E-520’s bundled lenses (45 options available) and Panasonic’s more extensive lens lineup (over 100) provide plenty of fast primes and zooms for portrait isolation. However, the G6’s better live view and exposure accuracy lean it toward portrait usability.

Landscape Photography: Dynamic Range and Resolution Matter

For landscape lovers, detail and tonal richness are the stars.

• Olympus E-520: The 10MP sensor limits fine detail, and dynamic range around 10.4 EV allows decent highlight and shadow retention but can struggle in high contrast scenes. No weather sealing means caution in rough conditions.

• Panasonic G6: Stretches dynamic range to 11.5 EV stops, a noticeable improvement that helps preserve sky detail and shadow texture. The 16MP sensor resolution is a solid middle ground for large prints. Weather sealing is absent though, which means you should pack rain covers or build-in protection.

The G6’s articulating touchscreen becomes useful for reviewing compositions in rugged terrain, and its wider ISO range helps capture handheld twilight landscapes.

Wildlife and Sports: AF Speed and Frame Rate Tells All

Chasing fast critters or athletes requires snappy autofocus and burst capability.

• Olympus E-520: The autofocus points are too sparse to follow fast-moving animals effectively. Continuous AF tracking isn’t available, and the 4fps burst rate shows its age when shooting action.

• Panasonic G6: Provides more AF points and subject tracking, allowing better focus retention on erratic subjects. The 7fps frame rate shines for burst sequences, though it can’t fully match professional sports cameras. Still, for amateurs or semi-pros, it’s a significant upgrade.

Street Photography: Discretion and Portability Count

Discretion comes with lighter weight and quiet operation.

• Olympus E-520: Not particularly stealthy, with a louder DSLR shutter and larger footprint.

• Panasonic G6: Smaller, lighter, with the mirrorless silent shutter option (though Olympus lacks silent shutter), making it great for candid shots.

Macro Photography: Magnification and Focusing Precision

Manual focusing precision and stabilization are key.

• Olympus E-520: Sensor-based image stabilization helps macro shots, but the lack of more focus points and assisted focusing features limit ease.

• Panasonic G6: Without in-body stabilization but with a more responsive autofocus and touch screen, focusing on macro subjects is easier.

Night and Astrophotography: High ISO and Exposure Flexibility

• Olympus E-520: Maxes at ISO 1600, which restricts handheld night shooting; dynamic range and noise control are middling.

• Panasonic G6: Roaring ISO ceiling at 25600 gives better noise control at low light, however, long exposure noise and heat need practical testing. Also offers bulb and manual modes suitable for astrophotography.

Video Capabilities: A Clear Advocate

This is where the G6 leaps ahead.

• Olympus E-520: No video capture capability.

• Panasonic G6: Records 1080p Full HD video at up to 60fps with progressive scan, great codecs (AVCHD and MPEG-4), built-in stereo mic port, HDMI out, touch focus during recording, and compact form - far more suited for content creators dabbling in hybrid photo-video use.

Travel and Everyday Versatility

• Olympus E-520: Bulky and heavier; however, long battery life of approximately 650 shots per charge is a huge plus for long trips without recharging.

• Panasonic G6: Lightweight and pocket-friendly but shorter battery life around 340 shots per charge demands spares or charging options on the go.

Its built-in wireless connectivity and NFC provide seamless image transfer, a convenience the Olympus lacks.

Reliability and Professional Workflow Integration

• Both cameras use standard raw formats and have good overall build quality but lack weather sealing, ruling them out for the roughest professional tasks.

• Storage types differ: Olympus uses CompactFlash and xD cards (more outdated), and Panasonic uses more modern SD card formats, widely supported by newer readers and computers.
