Olympus E-M10 IV vs Panasonic GF5: An Expert’s Hands-on Comparison for Enthusiasts and Professionals

Choosing the right mirrorless camera can be a daunting task, especially when looking between classic entries like the Olympus OM-D E-M10 IV and Panasonic Lumix DMC-GF5. Both share the Micro Four Thirds mount, but come from different generations - eight years apart - and embody distinct design philosophies and performance priorities. After personally testing thousands of cameras over my 15+ years in the field, I’m here to guide you through a deep dive into these two models, not just specs on paper, but real-world handling, image quality, and versatility across photography disciplines.

Whether you’re an aspiring enthusiast or a seasoned pro hunting for a reliable secondary body, this detailed comparison will help clarify which camera suits your needs best.

In Your Hands: Size, Ergonomics, and Build Quality

Starting with the tactile experience - one of the most important considerations when shooting hours at a time.

Both cameras embrace the compact ethos of the Micro Four Thirds system but differ notably in body style and heft. The Olympus E-M10 IV sports a classic SLR-style mirrorless design, offering substantial grip and physical controls. The Panasonic GF5, a rangefinder-style body, is smaller, lighter, and with a more minimalist layout.

Olympus E-M10 IV weighs in at 383 grams, measuring 122 x 84 x 49 mm. Its grippier and slightly bulkier chassis feels balanced, especially when paired with larger lenses, lending confidence during extended shooting sessions. The control dials and buttons are well-placed, responsive, and illuminated - features often missing at this price segment.

The Panasonic GF5, at just 267 grams and 108 x 67 x 37 mm, is noticeably more pocketable and sleek. However, the slim body compromises ergonomic comfort somewhat, with smaller buttons and less surface area to hold firmly, especially with heavier lenses.

Build quality is where both cameras show their entry-level status but in different ways. Neither offers weather sealing or ruggedness required for professional outdoor use. The Olympus feels more solid and durable, while the Panasonic sacrifices some robustness for portability.

For photographers prioritizing long shooting days with assured handling, the Olympus’s more substantial body and better control layout are clear advantages. Street photographers or casual users valuing inconspicuousness and pocketability might prefer the Panasonic.

Viewing and Composing: Viewfinders and Screens

Composing your shot conveniently and accurately is fundamental. Here again the two cameras play to different strengths.

The Olympus E-M10 IV comes equipped with a bright electronic viewfinder (EVF) boasting a 2.36-million-dot resolution and 100% coverage, coupled with a tilting 3-inch touchscreen LCD at 1,040k dots. This setup offers versatile shooting options - eye-level EVF for deliberate framing, or screen for awkward angles and video.

In contrast, the Panasonic GF5 omits an EVF altogether. You only get a fixed 3-inch touchscreen LCD with 920k dots - a decent panel but fixed and less sharp, with no eye-level option.

The lack of an EVF on the GF5 can make outdoor shooting challenging, especially in bright light where LCD glare is a concern. The E-M10 IV’s EVF addresses this perfectly with its crisp, lag-free view.

Touchscreen implementation is better executed with the Olympus, supporting more varied touch controls that speed up focus selection and menu navigation - a boon for hybrid shooters who rely heavily on quick adjustments.

For those shooting in bright daylight or preferring traditional eye-level composition, Olympus delivers a far superior experience. The GF5’s screen suffices mainly for casual or indoor use.

Sensor and Image Quality: Resolution, Dynamic Range, and Color Fidelity

Great images start from the sensor, and here the E-M10 IV clearly benefits from newer tech and higher resolution.

Both cameras use Four Thirds-sized CMOS sensors (~17.3 x 13 mm), but the Olympus boasts a 20-megapixel sensor, whereas the Panasonic GF5 offers 12 megapixels. That 8MP bump alone provides more flexibility with cropping and larger print sizes.

More importantly, the Olympus employs the modern TruePic VIII image processor, which, combined with the newer sensor design, delivers:

• Improved high-ISO noise performance with usable output up to ISO 3200-6400
• Wider dynamic range that preserves detail in shadows and highlights better
• Richer, more accurate color rendition and skin tones - paramount for portraits

The Panasonic’s 12MP sensor and older Venus Engine FHD processor show their age. Low-light color noise is heavier, and dynamic range is limited, evident in blown-out skies or lost shadow detail under challenging light. While still capable for casual shooting, it won’t satisfy demanding photographers seeking professional-grade images.

Both support RAW capture, but Olympus’s 20MP files offer a greater buffer in post-processing.

In my side-by-side tests shooting landscapes at sunset, Olympus’s sensor produced images with smoother gradients and more preserved highlight detail, whereas the Panasonic’s files struggled to retain color fidelity and detail in bright areas.

Autofocus System: Speed, Accuracy, and Tracking

Autofocus performance can make or break shooting fast-moving subjects or capturing fleeting moments.

The Olympus E-M10 IV features a 121-point contrast-detection AF system, with face-detection and continuous autofocus tracking. Although it lacks phase-detection pixels, its algorithm and processing power provide snappy, reliable autofocus across most situations.

The Panasonic GF5, with just 23 focus points and older contrast-only AF, understandably lags behind in responsiveness and accuracy, especially in low contrast or fast action.

• Olympus E-M10 IV: Quicker acquisition times (under 0.2 sec in good light), better predictive tracking, AF-C with smooth focus transitions
• Panasonic GF5: Slower AF, more hunting in low light, continuous AF less effective on moving subjects

For wildlife, sports, or spontaneous street photography where moments vanish quickly, Olympus’s focusing system delivers consistently better keeper rates.

However, for static subjects or slower-paced shooting, both cameras will autofocus adequately. Olympus’s advanced subject tracking (albeit no animal eye detection) does edge it as a more versatile all-rounder.

Speed and Shooting Modes: Burst Rates and Shutter Options

Evaluating burst performance and shutter mechanics helps determine suitability for action and sports.

The Olympus E-M10 IV offers 8.7 frames per second (fps) continuous shooting with mechanical shutter, up to 1/4000s max shutter speed, and an electronic shutter mode reaching 1/16000s silent operation.

The Panasonic GF5 shoots at a more modest 4 fps max, with standard mechanical shutter speeds maxing out at 1/4000s, but without an electronic shutter option.

This means Olympus allows faster capture of quick sequences - perfect for sports or wildlife - while Panasonic fits slower, more deliberate shooting.

The Olympus’s electronic shutter is also useful for quiet environments or when avoiding shutter shock, an advantage absent on the GF5.

Lens Ecosystem: Flexibility and Compatibility

Both cameras share the Micro Four Thirds mount, unlocking access to an extensive lens lineup.

Currently, there are over 100 native lenses available from multiple manufacturers including Olympus and Panasonic themselves. This provides everything from ultra-fast primes for portraits, rugged telephotos for wildlife, to stabilized macro lenses.

Because Olympus tends to optimize its own lenses and bodies for in-body image stabilization (IBIS) - the E-M10 IV features 5-axis sensor-based stabilization - it benefits from a stabilized, sharper shot even when using older lenses or those without optical stabilization. Panasonic GF5 lacks in-body stabilization, depending on lens IS alone.

If you foresee shooting varied genres requiring different lenses, Olympus’s ecosystem with IBIS integration provides more creative and technical freedom.

Build Details: Weather Sealing, Durability, and Flash

Neither camera offers professional-grade weather sealing; both are vulnerable to moisture and dust.

The Olympus E-M10 IV includes a built-in pop-up flash with a claimed range of 7.2m (ISO 200). It also supports external flash units via hot shoe, offering manual flash control and multiple flash modes - the kind portrait and event photographers appreciate.

The Panasonic GF5’s flash system is more basic: built-in flash with 6.3m range, no external flash support, and fewer modes.

From a durability standpoint, Olympus’s sturdier chassis offers more daily protection, while Panasonic’s lighter build requires more careful handling.

Video Capabilities: Resolution, Stabilization, and Audio

Video continues to be an important feature for hybrid shooters.

The Olympus E-M10 IV supports 4K UHD recording at 30p/25p/24p with a solid bitrate of 102 Mbps in MOV format (H.264 codec). Its 5-axis IBIS helps stabilize handheld footage. However, it lacks microphone and headphone jacks, something more advanced users will notice.

In contrast, the Panasonic GF5 is limited to Full HD 1080p at 60/50 fps, without 4K. No stabilization is offered without IBIS lenses. Its codec options are more limited (AVCHD and MPEG-4), and no external microphone support exists.

If you’re serious about video, especially 4K and stabilized footage, Olympus is clearly the better pick.

Battery Life and Storage

Both models use a single SD card slot compatible with SDHC and SDXC media. Olympus supports the faster UHS-II standard for quicker write speeds, beneficial for burst shooting and 4K video recording.

Battery life is identical on paper, rated at 360 shots per charge according to CIPA standards. Real-world results will vary, but Olympus’s more advanced processing and EVF usage may reduce endurance slightly.

Notably, the Panasonic GF5 uses a different and older battery type - check for availability if buying used.

Connectivity and Wireless Features

In today’s connected world, wireless capabilities affect your workflow.

Olympus E-M10 IV offers built-in Wi-Fi and Bluetooth for remote control and instant image transfer to smart devices - a huge convenience for tethered shooting or social sharing.

Panasonic GF5 disappoints here with no wireless support at all, reflecting its 2012 era design. You’ll depend on cables for transfer and no remote shooting options.

Price-to-Performance Ratio and Value Assessment

Currently priced around $699, the Olympus E-M10 IV delivers excellent value packed with modern features - 4K video, IBIS, a high-res EVF, fast AF, and a robust lens ecosystem.

The Panasonic GF5, originally priced near $600 back in 2012, now mostly appears used. While a solid beginner option in its day, its outdated sensor, weaker AF, lack of stabilization, and missing wireless limit its appeal today.

For new buyers, the Olympus clearly offers a more future-proof investment, balancing affordability with advanced technology.
