What grabbed me immediately was its unique hidden LCD display - a 3-inch tilting touchscreen that stays folded away until you tilt it down to compose shots from awkward angles or review images. This design encourages photographers to rely more on the built-in hybrid viewfinder, fostering a more immersive shooting experience especially on the street or in candid scenarios.

The SLR-Style Workhorse: Panasonic G85

In contrast, the Panasonic G85 sports a traditional SLR-style mirrorless design with a fully articulating 3-inch touchscreen - affording complete flexibility for vlogging, macro, and high or low shooting angles. Measuring slightly chunkier at 128 x 89 x 74 mm and weighing about 505g, it feels robust but remains easily portable for travel.

The grip on the G85 impressed me with its textured finish, giving me confidence for extended wildlife and sports shoots. The fully articulating screen also makes it incredibly versatile for video creators and photographers who frequently change their shooting angles.

Practical Tip: If street photography or stealth shooting appeal to you, the X-Pro3’s rangefinder ergonomics and hybrid viewfinder are a joy. For more generalist or multimedia use, including video, the G85’s articulating screen and familiar grip might serve better.

Sensor and Image Quality: Pixel Performance and Image Characteristics

Sensor technology is the beating heart of any camera and affects everything from resolution to dynamic range and noise handling.

APS-C Brilliance in the X-Pro3

The X-Pro3 boasts a 26MP APS-C X-Trans BSI-CMOS sensor measuring 23.5 x 15.6mm. This sensor size provides a larger sensor area of 366.6 mm², significantly improving light-gathering ability compared to smaller sensors. Fuji’s X-Trans design helps reduce moiré patterns without an optical low-pass filter, granting crisper images with excellent detail resolution.

In my landscape and portrait shots, the X-Pro3’s color reproduction - especially skin tones - is noticeably rich with a finely grained, filmic aesthetic. The sensor’s absence of an anti-aliasing filter gives superb sharpness, even wide open on prime lenses, preserving exquisite details in hair strands, fabric textures, and fine foliage.

Micro Four Thirds Flexibility in the G85

The Panasonic G85 features a 16MP Four Thirds CMOS sensor sized 17.3 x 13mm, which equates to a 224.9 mm² sensor area. While smaller than APS-C, the G85’s sensor still manages impressive clarity and color fidelity, thanks to effective noise reduction algorithms and lack of an anti-aliasing filter.

With a 2.1x crop factor, it packs a greater reach out of telephoto lenses, which is handy for wildlife and sports shooters on a budget without the bulk of longer primes. The sensor’s lower megapixel count results in slightly less resolution but enhances low-light capabilities by allowing larger pixel sizes.

Technical Insight: The larger APS-C sensor in the X-Pro3 gives it a clear edge in resolution and dynamic range potential, supporting high-quality large prints and detail retention in shadows and highlights. The G85’s Four Thirds sensor excels when lens reach and stabilization are prioritized over sheer resolution.

Viewing and Composing: Viewfinder and LCD Technologies

The viewfinder and LCD interface directly affect how photographers frame their every shot and interact with camera settings.

Hybrid Viewfinder Experience in X-Pro3

Fujifilm’s standout feature is its hybrid viewfinder combining a bright electronic OLED (3.69M dots) and an optical tunnel viewfinder. This system allows instantaneous switching between an EVF with live exposure preview and an OVF with a clear, immersive optical image reminiscent of classic rangefinders.

The EVF impresses with near lag-free refresh rates and vivid color rendition, crucial for evaluating exposure and white balance on the fly. The 95% coverage in the OVF encourages thoughtful, deliberate framing, especially for street and documentary photographers who value environmental context.

Fully Articulated Touchscreen and EVF in G85

The Panasonic relies solely on a high-quality 2360-dot electronic viewfinder, offering 100% frame coverage and a solid 0.74x magnification. It provides excellent brightness and crispness but lacks the hybrid option, so you lose the optical alternative.

Its fully articulating 3-inch touchscreen, though lower in resolution (1040k dots), supports intuitive touch focusing, image playback, and menu navigation. This flexibility benefits vloggers and macro shooters needing unconventional angles and easy selfie compositions.

Workflow Tip: For photographers accustomed to OVFs or those shooting street and reportage, the X-Pro3’s hybrid finder is a game-changer. For dynamic shooting styles requiring flexible screen positioning, the G85’s fully articulated display feels liberating.

Autofocus and Burst Shooting: Speed and Accuracy

A camera’s autofocus (AF) system and burst capabilities define its responsiveness and ability to capture decisive action moments.

Advanced Phase-Detect AF in X-Pro3

The X-Pro3 utilizes a hybrid autofocus system combining 425 phase-detection points, spread generously to cover most of the sensor’s area. This results in quick, precise AF lock, especially effective in good light and with face/eye detection enabled. The AF system tracks subjects smoothly in continuous mode, although it lacks dedicated animal eye AF, which may limit wildlife photographers seeking peak tracking finesse.

With an impressive 20 fps mechanical shutter continuous burst mode, the X-Pro3 handles sports and fast wildlife sequences reliably, assuming compatible UHS-II cards and ample buffer.

Contrast-Detect AF and Burst in G85

Panasonic’s G85 uses contrast-only autofocus with 49 AF points. While not considered cutting-edge by today’s standards, it performs admirably in well-lit conditions with decent subject tracking. However, low-contrast or fast-moving targets reveal limitations, especially compared to phase-detect systems.

The camera offers a solid 9 fps burst rate, suitable for casual sports and wildlife shooters, with a working buffer that manages sequences well.

Additional Benefit: The G85 includes focus bracketing and stacking, plus innovative post-focus functionality, great for macro and product photographers who need precise depth-of-field control.

Image Stabilization: Sharpening Without a Tripod

Stabilization technology can make a huge difference, especially in handheld low-light and video shooting.

• Fujifilm X-Pro3: Surprisingly lacks in-body image stabilization (IBIS), meaning image steadiness depends on stabilized lenses or support systems like gimbals or tripods.
• Panasonic G85: Features 5-axis sensor-based IBIS, markedly improving sharpness during handheld stills and 4K video, particularly with non-stabilized lenses.

In my tests focusing handheld at slower shutter speeds, the G85’s IBIS consistently produces sharper images with fewer motion blur artifacts. This makes it ideal for travelers and videographers who often shoot on the move without extra gear.
