Panasonic G85 vs Sony A7R: The Mirrorless Showdown through a Seasoned Photographer’s Lens

Choosing between the Panasonic Lumix G85 and the Sony Alpha A7R isn’t just a matter of specs - it’s about matching a camera’s character to your photographic style, workflow, and budget. Having spent over 15 years buried under various mirrorless systems, testing their mettle in the field, the studio, and everywhere in between, I’ve learned that a camera’s worth isn’t always measured in megapixels or frame rates alone - it’s about how all the pieces come together when you hit that shutter button.

Today, I’m diving deep into a hands-on, no-nonsense comparison of the Panasonic G85 and Sony A7R. Two cameras separated by sensor size, market tier, and era - yet both still relevant tools for certain users. So buckle up - here’s the lowdown on what these mirrorless contenders can really do across the board.

Getting to Know the Contenders: Physicality and Ergonomics

Before you even think about sensor tech or autofocus, how a camera feels in your hands can make or break your entire shooting experience. The G85 and A7R, though both SLR-style mirrorless models, offer different form factors and handling philosophies.

The Panasonic G85 is a Micro Four Thirds system camera, known for compactness and light weight without a major sacrifice in functionality. The Sony A7R sports full-frame chops in a slightly larger but still relatively trim body.

Let’s put these side by side visually:

Observing the size and grip contours, the G85’s chunkier grip and more pronounced button layout cater nicely to longer handholds. It feels reassuringly solid, and its 505-gram body encourages less hand fatigue during extensive shoots.

In contrast, the Sony A7R surprises with a slimmer profile and lighter 465 grams, yet it manages a very competent grip for its size. However, the relatively shallow grip may not be as comfortable for photographers with larger hands or when using big, heavy lenses.

Flip the cameras over to check the top decks and control layouts:

Here, the G85 shines in its thoughtful dials. Dedicated mode, exposure compensation, ISO, and shutter speed dials allow quick manual adjustments without diving into menus - a boon in action situations or outdoor shoots where you want to concentrate on composition.

The Sony A7R opts for a more minimalist look with fewer hard dials and reliance on multi-function buttons and menus. While customizable, it requires more menu navigation, which can slow you down if speed is essential.

Ergonomics verdict: For photographers who prize tactile control and grip comfort, especially those shooting extended sessions, the Panasonic G85 edges ahead. Meanwhile, the Sony A7R will appeal to users comfortable with menu-driven customization, prioritizing compactness.

Pixel Wars: Sensor Size, Resolution & Image Quality

Now, let’s get down to the megapixels and sensor physics that dictate core image potential. Sensor size and resolution are critical because they shape everything from depth of field behaviors to low-light sensitivity.

Here’s a straightforward visual comparison of the sensor footprints:

• Panasonic G85 packs a 16MP Four Thirds sensor (17.3 x 13 mm, 224.9 mm² area)
• Sony A7R rocks a 36MP full-frame sensor (35.9 x 24 mm, 861.6 mm² area)

First off, the resolution bump: Sony’s roughly double pixel count means images boast more detail, super handy for landscape or studio work where cropping or large prints are common.

Technically, the larger sensor also inherently offers a broader dynamic range and cleaner high-ISO performance - visible in DxOMark results:

The big sensor advantage translates to more detail retention in shadows/highlights and markedly improved noise control at elevated ISOs.

Still, don’t write off the G85. In daylight or controlled lighting conditions, its sensor produces vibrant, pleasing colors and respectable sharpness. And the absence of an anti-aliasing (AA) filter on both cameras helps preserve fine detail - no softening blur here.

For those wondering what the images actually look like from both bodies, here’s a gallery of diverse shot types:

Autofocus and Focus Performance: Speed and Precision in Real Life

Autofocus can be the make-or-break feature for disciplines like sports or wildlife photography where split-second sharpness matters more than megapixels.

The Panasonic G85 employs a contrast-detection AF system with 49 focus points, but no phase detection. It features face detection, 5-axis sensor stabilization aiding AF performance, and continuous AF modes that lock in quickly in good light.

Sony’s A7R, intriguingly, lacks phase detection AF altogether, relying fully on contrast detection with 25 AF points. It also offers face detection but no continuous tracking autofocus, a notable limitation for fast-moving subjects.

In practical tests, the G85’s AF was noticeably snappier in continuous shooting and tracking moving subjects, benefiting from modern contrast-detection algorithms paired with in-body image stabilization. Sony’s A7R did well with stationary subjects and single point focusing, but struggled to maintain focus on moving targets, making it less suited for wildlife or sports.

For those needing fast, reliable autofocus, especially in variable light or action scenarios, the G85 is surprisingly capable for its class and age.

Diverse Photographic Disciplines: Strengths and Blind Spots

With a grip on sensors and AF, let’s examine how these cameras excel or falter across a variety of genres.

Portrait Photography

Portraiture demands accurate skin tones, background separation (bokeh), and sharp eye detection.

The Sony A7R’s full frame sensor offers a narrow depth of field at wider apertures, creating that creamy, professional bokeh many portraitists crave. The higher resolution also captures subtle skin texture and tonal gradations, essential for retouchers and beauty work.

In contrast, the Panasonic G85’s smaller MFT sensor naturally produces deeper depth of field, requiring wider aperture lenses to approximate full-frame bokeh aesthetics. Skin tones are pleasing but less nuanced compared to the Sony.

Both cameras feature face detection AF - though neither offer robust eye detection (Sony lacking completely here, Panasonic better but not ultimate) - so manual focus assists can improve precision.

Landscape Photography

Landscape work favors dynamic range, resolution, weather sealing, and lens choices.

Sony’s higher dynamic range and resolution allow for rich shadow detail and printing large panoramic crops effortlessly. Meanwhile, the G85’s robust weather sealing means you can shoot confidently in mist, dust, or light rain - a valuable trait for those trekking in the wild.

Both can capture sharp landscapes, but if ultimate resolution and tonal latitude are priorities, Sony edges out.

Wildlife and Sports

For fast-moving subjects, autofocus tracking, burst speed, and reach matter.

The Panasonic G85 offers a healthy 9 fps burst and agile AF system, making it better suited for action.

The Sony A7R drags with 4 fps and less reliable continuous AF - limitations for chasing birds or sports.

Lens availability also shapes reach - Sony’s E-mount supports native telephotos for wildlife, but Panasonic’s Micro Four Thirds lenses benefit from a focal length multiplier (2.1x), effectively extending your telephoto reach on smaller lenses.

Street Photography

Street shooters seek discreteness, portability, and quick AF.

Sony’s slim, quiet body and smaller shutter travel suit candid work. The deeper grip on the G85 can feel bulky for quick, one-handed shooting.

Both have vari-angle or tilting LCDs, though Panasonic’s fully articulated touchscreen is more versatile for shooting awkward angles or selfies - a plus for street photographers shooting from waist level or unusual perspectives.

Macro Photography

Precision focus, magnification, and stabilization dominate here.

Panasonic’s in-body 5-axis stabilization combined with focus stacking and focus bracketing features empowers macro shooters to capture tack-sharp images handheld.

Sony A7R lacks stabilization, posing a disadvantage for handheld macro work.

Video Features: Going Beyond Stills

For hybrid shooters dabbling in video, capabilities and ergonomics should weigh heavily.

The Panasonic G85 is a proud 4K-capable camera offering UHD 30p recording at 100 Mbps in MP4 format, built-in image stabilization, and a microphone input (no headphone jack though). The articulated touchscreen helps for framing vlogs or dynamic video content.

Sony’s A7R caps at 1080p Full HD with frame rates up to 60p, also with microphone and headphone jacks - catering to more professional audio monitoring.

If video is a serious part of your workflow, the Panasonic’s native 4K and stabilization make it the natural choice. The Sony’s video capabilities feel basic, suitable for casual clips but lacking 4K’s buttery clarity.

Build Quality, Environmental Protection, and Battery Life

Both cameras feature environmental sealing, but neither is fully weatherproof, so some caution is warranted when shooting in rough conditions.

Battery life sits close:

• Panasonic G85 rates about 330 shots per charge
• Sony A7R slightly better at 340 shots

Not a huge difference, but worth noting for long trips without charging options.

Storage-wise, both use single SD card slots, with Sony additionally supporting Memory Stick formats - a niche feature but less relevant today.

User Interface, Screen, and Viewfinder Experience

Let’s check the usability factors that influence daily workflow:

The Panasonic G85 sports a fully articulated 3” touchscreen with 1040k-dot resolution, offering intuitive control and flexibility for tricky angles.

Sony’s A7R tilting 3” screen has a slightly higher resolution (1230k dots) but lacks touch functionality, which may slow options like focus point selection.

Both feature electronic viewfinders with similar resolutions (~2350k dots), though Panasonic’s offers a 0.74x magnification vs Sony’s 0.71x - very close, but good enough for sharp, lag-free framing.

Connectivity and Storage: Wired and Wireless Considerations

Both cameras possess built-in Wi-Fi for image transfer and remote control, but:

• Panasonic G85 does not include Bluetooth or NFC.
• Sony A7R includes NFC but lacks Bluetooth.

Given this article's 2024 lens, these wireless options might feel somewhat basic compared to newer models but were decent at their launch times.

USB 2.0 ports on both limit speedy file transfers compared to today’s USB-C standards, a consideration for backing up large RAW files swiftly.

Price-to-Performance Ratio: What Fits Your Wallet?

As of now (depending heavily on used and discount markets), approximate prices are:

• Panasonic G85: $900 USD street price new
• Sony A7R: Roughly $1900 USD

This stark difference reflects sensor size, era, and market positioning. The G85 is an aggressive value play packing strong features, whereas the A7R targets a pro-level full-frame resolution audience.
