Panasonic GX8 vs Sony A6300: The Hands-On Showdown of Advanced Mirrorless Cameras

In the bustling mid-2010s mirrorless marketplace, two contenders made significant waves: Panasonic’s Lumix DMC-GX8 and Sony’s Alpha a6300. Both target enthusiasts and professionals seeking compact, versatile systems that don’t compromise on image quality, speed, or features. Yet, beneath their similar price points and mirrorless credentials lies a wealth of technical nuance, design philosophy, and real-world performance differences that deeply influence which might serve you best.

Having spent countless hours running these cameras through rigorous field tests - shooting portraits in controlled studios, stalking wildlife in varied light, recording fast-paced sports, and traveling light through cities and landscapes - I’ll unpack the true character of each system here. This comparison isn’t just about specs but practical use and expertise gained from hands-on experiences. Let’s dive in.

The Physical Feel and Design DNA: Ergonomics That Shape the Experience

Handling a camera daily means the physical design matters as much as its guts. The Panasonic GX8 and Sony A6300 come from distinct ergonomic traditions. Panasonic’s GX8 is a Micro Four Thirds system camera with rangefinder-style styling showing off a uniquely deep grip and fully articulated screen, while Sony’s APS-C A6300 channels the minimalist, compact ethos typical of Sony’s E-mount line.

Panasonic GX8: Clocking in at 133x78x63 mm and just shy of 500 grams, the GX8 impresses with solid heft and an articulating 3-inch touchscreen with 1,040k dots resolution - a boon for awkward angles and creative compositions. Its deep grip and intuitive dial placements made the camera a joy to hold securely for extended shoots, especially when paired with longer lenses. This robust body includes environmental sealing, reassuring for outdoor use.

Sony A6300: At a smaller 120x67x49 mm and an impressively light 404g, the A6300 sports a tilting 3-inch screen (922k dots), but unfortunately lacks touchscreen support. Its grip is shallower, more suited to quick handling and portability rather than long-day comfort. Despite this, the build quality feels rugged and also carries dust and moisture resistance.

From experience, for event work or outdoor trips where you may switch lenses or grip for extended times, Panasonic’s GX8 is notably more comfortable and confidence-inspiring, especially for those with larger hands. Sony’s smaller footprint will lure street shooters and travelers who value discretion and lightweight gear.

Top-Down: Control Layout and Usability in Action

When you’re in the zone, menus and ergonomics can either facilitate creativity or trip you up. Both cameras offer extensive manual controls but differ in style.

The GX8 places an emphasis on physical dials and customizable buttons, including dual control dials for quick aperture/shutter speed adjustments, and an exposure compensation dial - rare in modern mirrorless cameras, and a feature many enthusiasts will cherish. The lack of a top screen is offset by a bright, high-res EVF (2.36M-dot), which offers excellent framing and info readouts.

Sony’s A6300 embraces a minimalist top deck without an exposure compensation dial, relying more on customizable buttons accessed via menus or on the rear. It shares a similar EVF resolution but with slightly less magnification (0.7x vs. 0.77x). The lack of dedicated physical dials here demands some acclimatization but doesn’t prevent fast operation for those familiar with Sony’s interface.

If you prize tactile feedback and direct control - a hallmark for professional and hybrid shooters - the GX8 wins hands down. Sony’s style is sleek and requires a learning curve but rewards those who favor button-press efficiency for fast shooting.

Sensor and Image Quality: Four Thirds vs APS-C – The Core Debate

The chipset is the heart of any camera, shaping dynamic range, noise handling, and color fidelity. On paper, the Sony A6300’s APS-C sensor has a size advantage over the Panasonic’s Four Thirds chip. This difference is critical, but as always, theoretical specs only tell part of the story.

• Panasonic GX8: 20MP Four Thirds CMOS sensor (17.3x13 mm). Offers a 2.1x crop factor, a 12.6 EV dynamic range on DxOMark, and decent 23.5-bit color depth. Native ISO spans 200-25600, with ISO 806 representing top low-light performance. Antialias filter is present, softening fine detail subtly but reducing moiré.

• Sony A6300: 24MP APS-C CMOS sensor (23.5x15.6 mm). Larger sensor area gives it a clear edge (13.7 EV dynamic range, 24.4-bit color depth, low light ISO rating of 1437). It also extends native ISO down to 100 and up to 25600, with boosted modes to 51200. Like the GX8, it employs an antialias filter.

In practice, the Sony A6300 consistently produces cleaner, crisper images, especially under low light, with better shadow detail retention and less luminance noise at high ISO - a tangible benefit when shooting indoors, in evenings, or astrophotography. The Panasonic is no slouch, though; its sensor’s smaller size means tighter depth of field control is trickier, but in well-lit conditions, it can yield very detailed images with beautiful micro-contrast.

The Rear Screen and EVF Interface: Seeing is Believing

A 3-inch rear screen is standard fare, but how the GX8 and A6300 implement this can affect workflow.

The GX8’s fully articulated touchscreen is a standout. I often found myself framing shots from waist level or overhead without strain, plus swift touch AF to nail focus on specific points. The sharpness and color rendering of the display are excellent for previewing exposure and colors in the field.

The A6300’s tilting screen, while a bit less flexible, is adequate for most shooting angles - just don’t expect touchscreen convenience. This is a noticeable omission for photographers who value quick point-and-shoot focus adjustments on a flexible touchscreen.

Both cameras have electronic viewfinders with similar resolutions. The Panasonic’s 0.77x magnification (vs. Sony’s 0.7x) imparts a slightly larger and more immersive view, although this comes down to personal preference.

Autofocus and Speed: How Fast and Accurate Are They?

Autofocus performance is crucial across genres, from decisive wildlife tracking to sports burst shooting and street candid captures.

Panasonic GX8 uses a contrast-detection AF system with 49 focus points but no phase-detection pixels, while Sony A6300 is armed with a hybrid AF system boasting 425 phase-detection points. The difference is pronounced.

• Tracking and Accuracy: Sony’s hybrid phase-detection system locks on swiftly and maintains continuous tracking exceptionally well, even with erratic movement. This is a major plus for wildlife and sports shooting. The GX8’s contrast-detection system, while accurate, tends to hunt in lower light or high-speed scenes, affecting capture rates.

• Continuous Shooting: The GX8 offers an impressive 12 fps burst, slightly ahead of Sony’s 11 fps. However, the A6300’s buffer clears faster and combined with superior AF tracking, it translates into more useful high-speed sequences.

• Face Detection and Eye AF: Both cameras perform face detection reliably. However, neither implements animal eye AF or advanced portrait eye AF - which would become common in later generations.

In real-world settings, I found the A6300 the more reliable partner for demanding subjects. Yet, the GX8’s burst speed and sensor-shift image stabilization (more on that shortly) bridge the gap somewhat when image sharpness is paramount.

Image Stabilization: The Panasonic GX8’s Sensor-Shift Advantage

One aspect where the GX8 shines blankly is sensor-based image stabilization. Unlike the Sony A6300, which does not have in-body image stabilization (IBIS) and relies on OSS-equipped lenses, the GX8 features 5-axis sensor-shift stabilization.

This technology boosts sharpness handheld at slower shutter speeds - a significant benefit when shooting landscapes in low light or close-up macros where camera shake degrades detail.

While Sony’s lack of IBIS means the shooter must pick lenses with optical stabilization, the Panasonic system is effective across all lens types on the Micro Four Thirds mount. In the field, I also appreciated the GX8’s in-camera stabilization assistance for video, smoothing footage further.

Lens Ecosystems and Compatibility: Micro Four Thirds vs Sony E Mount

Lens availability and versatility are major deciding factors. Panasonic’s GX8 uses the Micro Four Thirds (MFT) system, while the A6300 embraces Sony’s E-mount.

• Micro Four Thirds: Over 100 native lenses are available, covering everything from ultra-wide landscapes to fast telephotos, plus a strong third-party lens market and adapters for legacy glass. The smaller sensor means lenses and systems tend to be more compact and affordable.

• Sony E Mount: With 121 lenses listed in this comparison, Sony’s APS-C lens lineup is vast and growing quickly. It benefits from Sony’s full-frame FE glass compatibility (allowing users access to a full-frame lens pool in a crop-sensor body), plus high-quality primes and fast zooms optimized for clarity and speed.

In practice, Sony’s lens selection edges Panasonic’s slightly in terms of sheer variety and professional-grade optics, while Panasonic’s ecosystem champions compactness and cost efficiency. The choice will depend on your lens preferences and intended use.

Battery Life and Storage: Powering Your Shoots

Battery life can make or break a shoot. The Sony A6300 offers an estimated 400 shots per charge using the LCD (around 310 via EVF), slightly better than the GX8’s 330 shots estimate.

Both cameras use SD/SDHC/SDXC cards in a single card slot, which covers most photographers but might disappoint professionals used to dual slots for backup. USB 2.0 is the data transfer standard for both, which is unexceptional but sufficient. HDMI output and microphone ports are standard, though no headphone ports are included.

For extended sessions and power users, carrying extra batteries is advised, but Sony’s slightly superior battery endurance is a mild advantage.

Video Capabilities: 4K with Different Flavors

As hybrid shooters increasingly demand strong video features, these two have thoughtful offerings.

• Panasonic GX8: Shoots UHD 4K (3840x2160) at 30p and 24p using the Venus Engine processor. It also supports 4K Photo mode - allowing extraction of 8MP stills from 4K video frames - and timelapse recording natively. In-body stabilization aids smooth handheld video.

• Sony A6300: Delivers 4K 30p/24p in XAVC S codec - favored by pros for better bitrate and editing latitude - and supports high frame rate 1080p up to 120fps for slow motion. Lack of IBIS means video stabilization depends on lenses or digital means.

Both cameras feature microphone inputs for audio quality, but no headphone jack to monitor audio in real time, which is a drawback for serious videographers.

While the Sony A6300 offers superior codec options and high frame-rate slow motion, the GX8’s in-body stabilization and 4K Photo mode are practical tools for photographers integrating video and stills creatively.
