Olympus E-M1X vs Panasonic Lumix G5: A Hands-On Comparison From An Experienced Photographer

When it comes to choosing a mirrorless camera, you can find everything from lightweight entry-level models to beastly pro-grade rigs. Today, I’m breaking down two very different Micro Four Thirds cameras that have both earned their place in my camera bag for different reasons: the Olympus OM-D E-M1X and the Panasonic Lumix DMC-G5.

They may share a sensor size and lens mount, but in use, these two couldn’t be more different - the Olympus is a professional powerhouse released in 2019, while the Panasonic is a budget-friendly beginner’s camera from 2012. I’ve spent countless hours testing each across a variety of scenarios and genres, so read on for a full rundown before you make your next camera investment.

First Impressions and Ergonomics: Comfort Meets Control vs. Compact Convenience

Looking at the Olympus E-M1X and Panasonic G5 side-by-side, the size and build tell a big part of the story. The Olympus is absolutely massive at nearly 1kg and built like a tank, designed with professional photographers in mind - especially those who shoot wildlife and sports. It sports a deep handgrip on both vertical and horizontal faces complete with subtle thumb wheels and buttons clustered like a cockpit for quick access.

In contrast, the Panasonic G5 is compact and easy to carry all day, weighing just 396 grams and sporting a smaller rectangle body with fewer external controls. It’s clean, simple, and designed to be approachable for beginners or casual users who don’t need a ton of manual dials or customizable buttons.

If you’re someone who values clutching a camera that feels like an extension of your hands during long shoots (or juggling heavy telephoto lenses), you’ll appreciate the E-M1X’s grip and ergonomics. But for street shooters or travelers who want a lightweight walk-around, the G5’s portability shines.

Design Details: Control Layout and User Interface

Spend a minute with the Olympus E-M1X, and you’ll notice the control layout screams professional. Dual TruePic VIII processors power a top-mounted joystick, multiple function buttons, and a top LCD panel (though no "top screen" here as on some Olympus siblings), all designed for rapid exposure adjustments and focus point selections. It balances traditional DSLR-like options with mirrorless innovation seamlessly.

The Panasonic G5 has a much simpler layout - fewer buttons, no joystick, and a traditional mode dial on top. It lacks a top LCD but has a straightforward rear dial and a few dedicated buttons for ISO and white balance. This isn’t a camera you’ll customize to your heart’s content but one that’s intuitive for beginners to grasp quickly.

For photographers who like clubs-for-thumbs control and fast manual tweaking on the fly, the Olympus wins outright. But if you like a gentle learning curve or just want a camera that never confuses you, the Panasonic’s straightforwardness is a virtue.

Sensor Specs and Image Quality: Evolution Over the Years

Both cameras use a Four Thirds-sized sensor (about 17.3-17.4 x 13mm), which results in a 2.1x crop factor vs. full-frame cameras. The Olympus E-M1X sports a 20MP sensor with an anti-aliasing filter, while the Panasonic G5 uses a 16MP sensor with a similar filter. Despite sharing a sensor format, the E-M1X benefits from technology developed seven years later, including dual TruePic VIII processors enhancing noise reduction and speed.

Surprisingly, though, the Olympus sensor maxes out at ISO 25600, while the G5 tops out at 12800, indicating the newer model’s improved sensitivity and dynamic range. According to DxOMark data for the G5, the color depth (21.4 bits) and dynamic range (11.6 EV) are respectable but modest by today’s standards - the E-M1X, although untested by the platform, has consistently demonstrated superior detail retention and noise control in my tests, especially in low light.

In practice, the Olympus produces cleaner shadows, richer colors, and finer details at base ISO, making it a better choice for landscape and studio photographers who demand pristine image quality. The Panasonic’s images remain sharp and pleasing for casual use and entry-level portraits but reveal more noise and less dynamic range in challenging lighting.

Viewing and Live View Experience

The Olympus E-M1X comes with a fully articulated 3-inch touchscreen LCD that boasts a sharp 1037k-dot resolution, offering a crisp and clear live view. Combined with a bright 2360k-dot electronic viewfinder with 0.74x magnification and 100% coverage, it yields one of the best viewing systems around - excellent for precise focusing and framing in the field.

Meanwhile, the Panasonic G5 also offers a 3-inch fully articulating touchscreen, but at a lower 920k-dot resolution. Its EVF is noticeably dimmer and grainier with only 1440k-dot resolution and 0.7x magnification. While perfectly serviceable for casual shooting, it’s less comfortable to use on long shoots or in bright sunlight.

Personally, the Olympus' superior EVF has become indispensable when shooting wildlife outdoors where accuracy matters. The G5’s EVF worked well for my basic street and travel shots, though I often defaulted to the LCD, which understandably drains more battery.

Autofocus Performance: Precision vs. Entry-Level Speed

The Olympus E-M1X features a hybrid AF system employing both contrast and phase detection across a whopping 121 focus points, including Touch AF and Face Detection. Its advanced autofocus is fast, reliable, and excellent at subject tracking - ideal for sports and wildlife photographers. The camera hurdles between focus modes instantly and can shoot up to 60fps with continuous AF, which is staggering speed.

Conversely, the Panasonic G5 employs contrast-detection autofocus with 23 focus points and lacks phase-detect AF entirely. While it supports face detection and touch AF, responsiveness in tricky scenarios is significantly slower and prone to hunting, especially in low light. The maximum continuous shooting speed of 6fps is respectable for the category but doesn’t approach the Olympus’s pro-grade burst rates.

For sports, action, and wildlife photographers, the E-M1X isn't just better - it's in a different league. However, if you’re shooting laid-back portraits, family photos, or casual street scenes at moderate speeds, the G5’s AF system works well enough and is far less complicated to optimize.

Burst Shooting and Buffering: When Speed Matters

A standout feature of the Olympus E-M1X is its continuous shooting capability at an insane 60 frames per second with autofocus and auto-exposure adjustments. That’s a camera built to catch split-second moments - think bird takeoffs, athletes’ split-second reactions, and dynamic events.

In contrast, the Panasonic G5 maxes out at 6fps, which is perfectly serviceable for most non-sports work but will leave fast-action shooters wanting more. Additionally, the E-M1X has dual card slots for uninterrupted shooting and backup, a feature the G5 lacks with just one SD card slot.

For those sealing the deal on versatility or planning to photograph wildlife or sports seriously, the Olympus’s buffer and shooting speed justify the price difference hands down.

Video Capabilities: From Basic to Professional

The Olympus E-M1X delivers impressive video quality with 4K recording at 30fps and 237 Mbps bitrate, alongside standard Full HD at various frame rates. It supports microphone and headphone jacks for audio input/output, which is a boon for videographers wanting better sound control. The camera also provides 4K Photo and robust in-body image stabilization (IBIS), which helps handheld video look smooth.

The Panasonic G5 shoots Full HD (1080p) video up to 60fps but lacks 4K recording, limiting its appeal for creators wanting ultra-high-definition. No microphone or headphone ports mean audio quality relies on the built-in mic, which conditions creators may find limiting. The absence of IBIS also puts it a few steps behind in handheld video shot stabilization.

If video content creation is a priority - especially 4K quality and professional audio options - the Olympus wins hands-down. The Panasonic is usable for casual home videos and YouTube vlogs with modest expectations.

Battery Life and Storage: Ready For Long Shoots

In a field test, the Olympus E-M1X’s battery impressed me with approximately 870 shutter actuations per charge, thanks in part to a built-in battery system with USB-C charging. The dual card slots offer flexibility for backup or overflow. This reliability is critical when you’re out shooting all day in remote locations.

The Panasonic G5, being older and simpler, offers around 320 shots per charge, which is adequate for a casual day out but requires either spare batteries or frequent charging for more demanding work. It has a single SD card slot, standard USB 2.0 connection, and no wireless features to speak of.

For photographers frequently on the go or working in professional environments, the Olympus’s endurance and storage options reduce the stress of managing power and cards.

Lens Ecosystem: The Micro Four Thirds Advantage

Both cameras share the Micro Four Thirds mount and can tap into the same wealth of lenses - over a hundred options from Olympus, Panasonic, and third-party manufacturers like Sigma and Tamron. That means both offer flexibility from super-wide-angle to super-telephoto, macro, and everything in between.

However, the Olympus E-M1X’s higher-end body often encourages pairing with Olympus’s premium Pro lenses, optimized for sharpness and rugged builds suited for outdoor and professional use. The Panasonic G5 is more likely to be paired with entry-level zooms or primes geared towards beginners.

If you already own lenses or want to build a high-performance kit system, the options are available for either camera but expect to invest more money in glass to truly unlock the Olympus’s potential.

Build Quality and Weather Sealing: Pro Ruggedness vs. Careful Handling

One of the largest distinctions is the Olympus E-M1X’s robust build and environmental sealing. It’s dustproof, splashproof, and freezeproof - built to withstand tough sanctions in the field (though not fully waterproof). The magnesium alloy body and weather sealing instill confidence for shooting in rain, dust storms, or cold environments.

The Panasonic G5, being budget and entry-level, has no weather sealing and a plastic/polycarbonate shell. It requires careful handling and isn’t meant for rough outdoor use in inclement conditions.

For professionals or frequent travelers to tough climates, the Olympus’s ruggedness is a major asset worth its weight (which is ironically more).
