Olympus E-M10 IV vs Panasonic G85: Which Micro Four Thirds Mirrorless Camera Fits Your Photography Life?

Having spent the last 15+ years examining, testing, and shooting with countless cameras, I’ve seen how specs on paper only tell half the story. The real test is in real-world handling, image quality under various conditions, and how a camera’s features align with your unique photography goals. Today, I’m bringing together two beloved Micro Four Thirds mirrorless models that cater to differing users and budgets - the Olympus OM-D E-M10 IV and the Panasonic Lumix DMC-G85.

Throughout this deep dive, we’ll explore their build, sensor and image performance, autofocus, ergonomics, lens compatibility, and more. I’ve personally shot portraits, landscapes, wildlife, street scenes, macro, video clips, and nighttime astro photos with both cameras - so expect honest, experience-backed insights. Whether you're hunting for an entry-level marvel or an advanced hybrid workhorse, by the end, you’ll have clear guidance on which Micro Four Thirds camera strives to meet your needs.

Getting a Feel: Size, Design, and Controls

First impressions matter, so I picked up both bodies to compare ergonomics - a critical aspect for day-long shoots or travel.

Olympus E-M10 IV vs Panasonic G85 size comparison

The Olympus E-M10 IV is notably compact and light, weighing only 383g with dimensions of 122x84x49mm. In contrast, the Panasonic G85 is bulkier at 505g and larger at 128x89x74mm. This size and weight difference is noticeable in hand; the E-M10 IV feels spry and pocketable, ideal for casual outings or street photography where portability and discreteness are priorities.

On the other hand, the G85’s heft translates to a more substantial grip - providing extra comfort and stability during extended handheld shooting sessions, especially with bigger lenses. I found it a better match for wildlife and sports where a steady hold matters.

Looking at the control layout…

Olympus favors a traditional DSLR-style top with classic dials for exposure compensation, shooting modes, and a shutter speed dial. These encourage tactile control, fast adjustments, and help keep the camera in manual or aperture priority mode without fumbling menus.

Panasonic G85 leans into a more modern design with a robust mode dial but fewer physical dials overall, pushing some settings into the rear control wheel or touchscreen menus. Its fully articulated screen (compared to Olympus’s tilting screen) provides more shooting angles, particularly beneficial for overhead or low-angle shots.

The Core: Sensor Specs and Image Quality Reality Check

Both cameras use a Four Thirds sensor (17.3x13mm-ish sensor size), standard in the Micro Four Thirds system, which strikes a good balance between sensor size, lens compactness, and system versatility. However:

Olympus E-M10 IV vs Panasonic G85 sensor size comparison

  • Olympus E-M10 IV boasts a 20MP resolution sensor with a traditional anti-aliasing filter.

  • Panasonic G85 uses a 16MP sensor but omits the anti-aliasing filter (OLPF), boosting potential resolution and fine detail rendering.

In hands-on tests, Olympus produces punchy, vibrant images with nicely rendered skin tones - Olympus’s TruePic VIII processor adds pleasing color science that leans slightly warm, flattering for portraits. The 20MP resolution gives more cropping flexibility, useful when you discover a distant subject unexpectedly.

Panasonic’s 16MP sensor, paired with the absence of the AA filter, yields sharper details - perfect for landscapes and macro shots where texture is king. The color reproduction is neutral, leaning slightly toward accuracy over stylized rendering, allowing for more latitude in post-processing.

Regarding dynamic range and low-light, the Lumix G85 outperforms Olympus slightly, with its DxOmark scores showing better noise control and dynamic range, thanks partly to newer sensor tech despite the age difference. The E-M10 IV holds its own, but you’ll see more noise at ISO 3200+.

Through the Viewfinder and Screen: What You See is What You Get

Shooting experience isn’t just image quality - how you compose and review images matters deeply.

Olympus E-M10 IV vs Panasonic G85 Screen and Viewfinder comparison

I appreciate the Olympus’s 3-inch tilting touchscreen - it provides flexibility for waist-level or high-angle snaps but doesn’t pull all the way around. The touchscreen is responsive but implemented more for joystick-style AF point selection and menu navigation.

The Panasonic G85, however, sports a fully articulated 3-inch touchscreen that flips out and rotates. This articulation is vital for video shooters and vloggers or when working in awkward positions during macro or street shoots.

Electronic viewfinders on both have the same resolution: 2.36 million dots with 100% coverage, excellent for framing and previewing exposure. Still, Panasonic’s 0.74x magnification surpasses Olympus’s 0.62x, rendering a larger and more immersive viewfinder image. This is a key advantage for critical manual focusing or long sessions in bright sunlight where LCD screens wash out.

Autofocus: Tracking Your Moments with Precision and Speed

Autofocus is where real-world performance shines or stumbles - especially with moving subjects like kids, wildlife, or sports.

Both cameras use contrast-detection AF systems, forgoing hybrid or phase detection AF on their sensors, but the Panasonic G85 uses an advanced DFD (Depth From Defocus) system, enhancing continuous tracking abilities.

Olympus E-M10 IV offers 121 phase-detect contrast points but relies on pure contrast detection for focusing (no on-sensor phase detection). Its Eye Detection AF works well for portraits, locking onto faces smoothly with decent speed and accuracy. However, it lacks animal eye detection, so wildlife portraiture - especially of animals - is less ideal.

Panasonic G85 features 49 AF points with DFD technology, delivering faster and more reliable autofocus in continuous tracking. In practice, I found the G85 better at maintaining focus on birds in flight or fast-moving children during play. The burst shooting rate is marginally higher on the G85 (9 fps vs 8.7 fps), a small but meaningful boost for sports or wildlife enthusiasts.

Across Photography Genres: What Each Camera Excels At

Let’s break down how these cameras stack up for the major photographic disciplines.

Portrait Photography

The Olympus’s warmer color rendition and slightly higher resolving power contribute to flattering skin tones and creamy bokeh, aided by the vast Micro Four Thirds lens selection with many fast primes. Eye detection AF helps lock focus on human subjects, making it very user-friendly for casual portraits. However, the textured background blur from Olympus’s sensor and lens combo is slightly less smooth compared to some full-frame rivals but works well in the price bracket.

G85’s color is neutral and accurate, which pros may prefer, especially for studio or editorial use where skin tones are fine-tuned later. The solid build and weather sealing allow outdoor portrait use in diverse environments.

Landscape Photography

Panasonic is the stronger choice here - the slightly sharper sensor without an AA filter, broader dynamic range, and weather sealing make it more suited for challenging locations like windy coastlines or dusty trails. I’ve lugged the G85 through several landscape hikes, appreciating its resistance to light rain and dust.

Olympus, while lighter and easier to carry, lacks the environmental sealing. You’ll want to be cautious in adverse weather or invest in protective covers.

Wildlife and Sports Photography

Both cameras use Micro Four Thirds lenses with a 2.1x crop factor, effectively doubling focal length reach - a benefit for telephoto wildlife or sports lenses.

However, Panasonic’s G85 autofocus tracking systems and faster continuous shooting give it the edge in capturing decisive moments. Its more substantial grip improves handling with long, heavy lenses.

Olympus’ system can keep up but demands more patience - it occasionally hunts in low contrast or dim light, which can frustrate action shooters.

Street Photography

Here, Olympus shines in portability and discretion. Its smaller form factor and quieter electronic shutter make it easier to blend in and shoot candid street scenes. The fast touch-to-focus system enables swift framing and capture without raising attention.

Panasonic’s bigger body takes a more deliberate presence on city streets but remains relatively stealthy compared to DSLRs. Full articulation is less useful here but appreciated for capturing low or unusual perspectives.

Macro Photography

In macro work, precision focusing and stabilization matter. Both cameras offer sensor-based 5-axis image stabilization, which aids in handheld close-up shots.

I found the Panasonic’s focus bracketing and stacking capabilities give it a notable advantage - allowing for extended depth of field in focus-stacked macro series, an invaluable tool for enthusiasts and professionals alike. Olympus supports focus bracketing but lacks stacking and post-focus modes offered by Panasonic.

Night and Astro Photography

High ISO noise performance is crucial. Panasonic edges out Olympus here, maintaining cleaner images up to ISO 3200 and beyond. The more neutral color profile aids in natural astrophotography post-processing.

Long exposure flexibility, extensive manual controls, and low-light AF help both models produce satisfying night shots, but the G85’s weather sealing adds peace of mind during late-night outdoor sessions.

Video Capabilities

Panasonic’s G85 is famous for solid 4K video with 30p recording at 100 Mbps, internal 5-axis stabilization, a microphone input jack, and the flexibility of an articulated screen - everything casual filmmakers or vloggers need.

Olympus E-M10 IV also shoots 4K UHD at 30p but lacks a microphone input, limiting audio quality control options. Its 102 Mbps bitrate is comparable, but the screen’s limited tilt reduces framing versatility for video.

Panasonic additionally supports 4K Photo modes letting users grab high-res stills from video, very handy for action sequences.

Reliability, Battery, and Storage

Panasonic’s G85 draws power from a slightly larger battery pack, offering about 330 shot capacity per charge in typical use - decent but not outstanding. Olympus excels slightly with 360 shots per charge.

Both cameras use a single SD card slot supporting UHS-II transfers for fast write speeds. The Panasonic uses SDHC/SDXC cards; Olympus supports the full range including UHS-II, ensuring flexible storage choices.

Connectivity includes built-in Wi-Fi for remote control and image transfer; Olympus offers Bluetooth as well, enabling lower power device connections.

Lens Ecosystem and Compatibility: Micro Four Thirds Wins

Both cameras benefit from the robust Micro Four Thirds lens lineup featuring over 100 lens choices from Olympus, Panasonic, Sigma, and others. The 2.1x crop factor effectively doubles your focal lengths; a 45mm lens behaves like ~90mm on full-frame, perfect for portraits and telephoto needs.

Olympus offers some exceptional prime and pancake lenses optimized for their bodies, maximizing compactness and optical performance.

Panasonic excels with several stabilized lenses and fast-aperture zoom primes suitable for pro video and photo work.

Putting It All Together: Performance Scores and Evaluations

Let’s summarize using industry-standard metrics and practical performance outcomes.

The Panasonic G85’s higher DxOmark color depth (22.8 vs untested/nominal), dynamic range (12.5 vs nominal), and low-light ISO (656 vs nominal) metrics correlate to superior raw image quality potential, especially in demanding shooting contexts.

Olympus scores highly for portability and user-friendly controls, favoring beginners and casual shooters.
