Olympus PEN-F vs Panasonic Lumix GM5: Which Micro Four Thirds Mirrorless Stands Out in 2024?

Choosing between the Olympus PEN-F and the Panasonic Lumix GM5 can feel like navigating a maze. Both cameras pack the hallmark Micro Four Thirds system into compact, rangefinder-style mirrorless bodies, but they target distinct users. With over 15 years of testing cameras across genres, I've put these two through rigorous hands-on evaluations, diving deeply into sensor technology, autofocus, ergonomics, and real-world performance. This article breaks down vital differences and helps you find the one that fits your creative journey, from casual street snaps to professional portraiture and beyond.

First Impressions: Size, Styling, and Handling

When you pick up these cameras, the physical and ergonomic differences immediately stand out.

The PEN-F carries a solid heft and classic retro flair, featuring dedicated physical dials for ISO, shutter speed, exposure compensation, and even a unique front control dial. This layout caters to photographers who want direct tactile control without diving deep into menus.

In contrast, the GM5 is incredibly petite - it's one of the smallest cameras with a built-in electronic viewfinder (EVF) on the market. Its minimalist design leads to fewer external controls but maximum portability. While you get fewer dedicated buttons, touchscreen operation helps compensate, though the compact body means some handling quirks if you have larger hands.

Ergonomic Verdict: If you prioritize a confident grip and physical controls, the PEN-F delivers a more refined shooting experience. For ultra-light, pocketable use - perfect for travel or street photography - the GM5 excels.

Sensor and Image Quality: Technical Heart of Both Cameras

Both cameras share the Micro Four Thirds sensor size (17.3 mm × 13 mm), but their sensor resolutions differ. The PEN-F features a 20-megapixel sensor, while the GM5 has a 16-megapixel sensor, reflecting their release timeframes and intended markets.

When tested under varied lighting scenarios, the PEN-F's 20 MP sensor captured finer detail with less noise at higher ISOs, thanks partly to the more recent TruePic VII image processor. Dynamic range readings at base ISO were also stronger - important for landscapes and portraits with high contrast scenes.

DxO Mark benchmarks support this real-world testing, showing the PEN-F leads with a 74 overall score versus the GM5's 66, notably in color depth (23.1 vs 22.1) and low-light ISO performance.

You’ll notice the PEN-F’s images retain better shadow detail and show smoother gradation in skin tones - critical for portrait work. The GM5’s 16 MP sensor still delivers respectable image quality suitable for web publishing and small prints but lacks some finesse in complex lighting.

Viewing Experience: EVF and LCD Screens Compared

With mirrorless cameras, the viewfinder and on-screen interface impact your shooting comfort immensely.

The PEN-F features a bright, crisp EVF with a 0.62x magnification that offers a larger, clearer preview of your composition - invaluable for framing detailed scenes or working in bright conditions. Its fully articulating touchscreen offers flexibility for shooting at strange angles and vlogging.

The GM5’s EVF, though smaller and lower in resolution, remains usable but less immersive. The fixed rear screen limits flexibility, and while its touchscreen helps navigate settings, the smaller real estate means less preview versatility.

Autofocus Performance: Keeping Up with Your Shots

Autofocus (AF) technology has evolved rapidly, and both cameras use contrast detection AF systems with 81 points on the PEN-F and 23 on the GM5.

While neither model uses phase detection AF, the large number of AF points on the PEN-F provides more accurate and faster autofocus overall, especially in continuous mode and tracking fast-moving subjects.

In practical testing:

• The PEN-F’s AF locked more consistently on eyes and faces, improving portrait and street photography usability.
• Burst mode at 10fps on the PEN-F paired with effective AF tracking suits action and wildlife better.
• The GM5’s AF felt slower and a bit more prone to hunting in low-contrast or dim conditions, while its 5.8fps burst rate limits capturing fast action but suffices for casual shooting.

Burst Shooting and Shutter Performance: Action and Silence

The PEN-F boasts a max shutter speed of 1/8000s mechanical and 1/16000s electronic shutter. The GM5's mechanical shutter caps at 1/500s, with the electronic shutter at 1/16000s as well.

Faster shutter speeds and burst rates on the PEN-F allow freeze-frame capture of fast-moving subjects and bright daylight shooting at wide apertures - crucial for wildlife and sports photography.

Silent shutter capability on both supports street and event photography where discretion is necessary. However, the PEN-F combines this with superior buffer depth, meaning you can shoot longer bursts without slowing down.

Image Stabilization and Lens Compatibility

The PEN-F includes built-in 5-axis sensor stabilization; the GM5 lacks in-body image stabilization (IBIS) and relies on lens-based stabilization only.

This difference is critical for:

• Handheld shooting in low light or macro photography
• Video stabilization
• Improving sharpness with telephoto lenses

Both cameras use the Micro Four Thirds mount, benefiting from a mature ecosystem of over 100 lenses. You'll find everything from fast primes for portraits, super-telephotos for wildlife, to compact zooms for travel. The PEN-F’s IBIS pairs well with any lens, greatly increasing versatility.

Video Capabilities: Beyond Stills

Neither camera pushes the limits of 4K video in terms of resolution, but both support Full HD 1080p capture.

The PEN-F’s 5-axis stabilization gives a clear edge for handheld video, making your footage smoother without a gimbal. However, neither camera supports external microphones or headphones, limiting audio options for serious videographers.
