Panasonic G85 vs Sony FX30: A Deep Dive into Two Advanced Mirrorless Cameras

Choosing the right advanced mirrorless camera can be daunting with so many excellent options on the market. Today, I’m comparing two popular models that appeal to enthusiasts and professionals alike: Panasonic Lumix G85 and Sony FX30. Both pack impressive features but serve slightly different photographic and video needs.

I have extensively tested these cameras in varied real-world conditions to bring you an honest, firsthand comparison brimming with practical insights. We’ll cover handling, image quality, focusing, video, and much more - all to help you decide which is the better fit for your craft and budget.

Physical Size, Build, and Ergonomics: Handling in Hand

When you pick up a camera, ergonomics plays a surprisingly large role in your experience, especially for longer shoots.

The Panasonic G85 adopts a traditional SLR-style mirrorless body with a pronounced grip, offering secure, comfortable handling even for larger hands. Its dimensions are about 128x89x74mm, and it weighs approximately 505g with battery. The body is weather-sealed, making it shock-resistant against dust and light rain - a boon for outdoor shoots.

The Sony FX30, meanwhile, features a more compact, rangefinder-style mirrorless body measuring 130x78x85mm and weighing around 646g. Despite the smaller footprint, it feels sturdy and well balanced with heavier lens setups. Like the G85, it includes weather sealing, making both cameras capable of reliable performance in less-than-ideal weather.

From my time using both, the Panasonic’s larger handgrip gives it an edge for comfortable handheld shooting over extended periods. However, if portability and a more pocketable shape matter, the FX30’s sleek form is a clear plus.

Control Layout & Interface

The usability of camera controls can dramatically speed up your workflow or get in the way when you’re under pressure.

The G85 has a traditional control layout with tactile dials for shutter speed, exposure compensation, and ISO. The buttons are well spaced but simple, putting key functions like ISO and white balance a thumb’s reach.

The FX30 takes a minimalist approach in line with modern Sony cameras, with multifunction dials and menu-driven options. Without a viewfinder (more on this in a moment), you rely heavily on its touchscreen and external monitor.

Personally, I found the G85’s direct dials faster for intuitive exposure control, especially in dynamic shooting conditions, while the FX30 reveals its strength once you’ve tailored its buttons and touchscreen to your style.

Sensor, Image Quality & Low-Light Performance: Pixel Peeping and Beyond

At the heart of every camera lies its sensor. Here we find major differentiators between these two.

The Panasonic G85 features a 16MP Four Thirds sensor measuring 17.3x13mm, with no antialiasing filter to preserve sharpness. Its official base ISO is 200, expandable down to 100, and max at 25600. According to DxOMark testing, the G85 scores well for dynamic range (~12.5 stops) and color depth (22.8 bits) - quite respectable for Micro Four Thirds.

Sony FX30 sports a 26MP APS-C BSI-CMOS sensor sized 23.5x15.6mm, larger than the G85’s. BSI (Backside Illuminated) design improves light gathering efficiency, contributing to better noise control - especially crucial for low-light and video. With a native ISO range from 100 to 32000 (expandable to 50 - 102400), the FX30 is more versatile in challenging lighting.

In my field tests, the FX30 delivered noticeably cleaner images at ISO 3200 and up, maintaining better color fidelity. The G85’s images were excellent under good light but saw noise creeping in beyond ISO 1600, typical for its sensor size. The wider dynamic range of the FX30 also helped preserve detail in shadows during high contrast scenes such as landscapes and interiors.

The downside for the FX30 is the absence of an antialiasing filter, which sometimes leads to slight moiré patterns - rarely a practical problem but worth being aware of.

Viewfinder and Screen: Composing Your Shot Your Way

Both cameras go about framing differently:

• The Panasonic G85 includes a 2.36M-dot electronic viewfinder with 100% coverage and 0.74x magnification. This provides a bright, sharp image, very useful under bright sunlight or critical focusing.

• The Sony FX30 has no built-in viewfinder and relies solely on its 3-inch fully articulated 2.36M-dot touchscreen LCD for composition.

I found the G85’s EVF indispensable when shooting outdoors, providing a refuge from glare. The FX30’s large, bright touchscreen is fantastic for video work, especially when paired with external monitors or high-angle shooting rigs, but can challenge precise framing on bright days.

Autofocus: Speed, Precision, and Tracking

The autofocus system is crucial - it can make or break a shoot.

The Panasonic G85 employs a contrast-detection AF system with 49 focus points. It supports face detection and offers continuous AF modes, but lacks phase-detection measurement sensors and animal eye AF. While quick and accurate in good lighting, it can struggle with fast-moving subjects or in low light.

Sony FX30 uses Sony’s advanced hybrid phase-detection AF with 759 points distributed across the frame, delivering exceptional speed and accuracy. It features Real-time Eye AF for humans and animals, along with tracking AF that maintains sharp focus on moving subjects with remarkable reliability.

From my experience shooting fast action and wildlife, the FX30’s AF system consistently outperforms the G85, providing more positive lock-on and smoother tracking for unpredictable subjects.

Burst Shooting and Buffer: Catching the Decisive Moment

• Panasonic G85 shoots up to 9 frames per second, which is solid for its class.
• Sony FX30 offers 10 frames per second, slightly faster, benefiting sports and wildlife shooters needing every fraction of a second.

Buffer depth favors the FX30 as well with dual card slots capable of high-speed CFexpress Type A and SD cards versus the single SD card slot of G85, giving it a definite edge for extended burst sequences and video recording reliability.

Video Capabilities: Beyond Stills - The Cinematic Edge

Both cameras appeal to hybrid shooters but differ significantly in video functionality.

Panasonic G85 Video Strengths

• 4K UHD up to 30p at 100 Mbps.
• 4K Photo Mode for extracting high-res stills.
• In-body 5-axis stabilization aids smooth handheld footage.
• Microphone input, but no headphone jack for audio monitoring.
• AVCHD and MP4 recording formats.

Sony FX30 Video Strengths

• 4K UHD up to 120p/100 Mbps with high-quality XAVC HS codec.
• Supports S-Log3 and HLG profiles for professional color grading.
• Advanced video codecs with H.265 for efficient compression.
• Both mic and headphone jacks for complete audio control.
• Dual SD/CFexpress Type A slots support longer continuous recording.
• No built-in flash, reflecting its video-centric design.

In my hands, the FX30 clearly caters to professional videographers with versatile formats, higher frame rates, and more comprehensive audio options. The G85 serves well for casual video or hybrid shooters prioritizing stills.

Lens Ecosystem: Find the Perfect Lens for Your Style

• Panasonic G85 uses the Micro Four Thirds mount, which boasts a long-established ecosystem with over 100 native and third-party lenses. Its smaller sensor also means lenses are generally more compact and affordable.

• Sony FX30 uses the Sony E mount, supporting a vast collection of APS-C and full-frame lenses from Sony and third-party makers. This allows great flexibility but lenses are often larger and pricier.

Sony’s glass lineup tends to skew towards professional cine-style zooms and primes with state-of-the-art optics, best matching the FX30’s video ambitions. Panasonic’s MFT lenses provide value, portability, and wide-angle options highly favored in travel and street photography.

Battery Life and Storage: Keeping the Camera Rolling

• Panasonic G85 offers about 330 shots per charge, which is adequate but will often necessitate a spare battery on full-day sessions.
• Sony FX30 impresses with an estimated 570 shots per charge, a significant advantage for long shoots or travel.

The FX30’s dual card slots provide built-in redundancy or overflow capabilities, enhancing reliability critical for professional workflows. The G85’s single SD slot is more limiting for video and fast action photographers.

Connectivity Features: Sharing and Remote Control

Both feature built-in wireless connectivity for image transfer and remote shooting apps. Sony adds Bluetooth, which enables an always-on connection for faster pairing, while Panasonic sticks solely to Wi-Fi.

I found Sony’s superior USB 3.2 Gen 1 port better for tethered shooting and rapid file transfers compared to Panasonic’s older USB 2.0 implementation.

Price-to-Performance: What You Get for Your Money

Current pricing places the Panasonic G85 around $900, well positioned as a feature-packed advanced mirrorless for stills and casual video.

The Sony FX30 sits near $1800, almost double the price. This premium reflects its more advanced sensor, video capabilities, and professional features.

If your priority is hybrid shooting with occasional video and excellent portability, the G85 remains an exceptional value. But serious videographers and pro photographers who demand top-tier autofocus, video specs, and future-proof infrastructure will appreciate the FX30’s costs.
