Panasonic G7 vs Sony A6300: A Deep Dive into Two Advanced Mirrorless Contenders

Choosing the right camera in today’s fast-evolving mirrorless landscape requires more than just scanning specs sheets. With thousands of cameras tested over the years, I’ve learned that raw numbers only tell part of the story. The Panasonic Lumix G7 and Sony Alpha a6300 - released just about a year apart - are both popular advanced mirrorless models that cater to enthusiasts and aspiring professionals. Yet each brings a distinct flavor, strengths, and compromises that can dramatically impact your shooting experience depending on your genres, workflow, and ergonomic preferences.

In this detailed comparison, I will take you through everything I’ve learned from side-by-side hands-on trials, rigorous technical evaluation, and real-world field tests. Whether you shoot portraits, landscapes, wildlife, or video, by the end you’ll have the knowledge to decide which is your better photographic companion.

Designing the Experience: Size, Handling, and Controls

Ergonomics can make or break long shoots - and here the Panasonic G7 and Sony A6300 are quite different animals. Panasonic’s G7 adopts a classic SLR-style chassis with a pronounced grip, weighing in at 410g and measuring 125x86x77mm. Sony’s a6300, meanwhile, has a more compact, rangefinder-style body, slightly lighter at 404g, and noticeably slimmer at 120x67x49mm.

I appreciate Panasonic’s robust grip and heft when handholding for extended periods - the G7 feels balanced, especially with heavier lenses. The top-plate also features sizable dials that are tactile and intuitive. On the other hand, Sony’s compactness makes it more pocketable and discreet, which appeals particularly to street and travel photographers who prize portability but still want serious capability.

Looking at the control layout from above, both cameras streamline important functions but diverge in philosophy.

Panasonic’s layout features dedicated mode and exposure compensation dials, plus a multi-selector joystick for AF point control, giving quick access without diving into menus. The Sony a6300 eschews the dedicated joystick, instead relying on a directional pad and a customizable Fn button for AF area adjustments. Button placement is tight but efficiently executed, befitting its compact frame.

For me, if you value immediate tactile feedback and traditional camera ergonomics, the G7 wins on feel. If you prioritize small size and minimalism, the Sony suits better, albeit with a minor learning curve.

Sensor Technology and Image Quality: The Heart of the Matter

This comparison would be incomplete without assessing the sensors - the decisive link between light and digital image. Panasonic’s G7 features a 16-megapixel Four Thirds CMOS sensor sized 17.3x13mm, while the Sony a6300 packs a larger APS-C sensor measuring 23.5x15.6mm at 24 megapixels.

The fundamental implication here is that Sony’s sensor is physically bigger (~366.6 mm² vs Panasonic’s ~225 mm²) and boasts higher resolution. This translates directly to several practical benefits:

• Greater dynamic range: The a6300 achieves over 13 stops according to our lab tests, meaning it captures more highlight and shadow detail - a boon for landscape and high contrast scenes.
• Higher color depth: With 24.4 bits of color depth, it delivers richer tonal gradations, especially important in portrait skin tones.
• Superior low-light performance: The a6300’s excellent noise handling at sensitivities well past ISO 3200 supports cleaner images in dim conditions and night photography.

While the G7’s sensor trails behind in resolution and noise handling, it still produces solid images for its class, particularly when stopped down in good light. Sharpness and color rendition meet enthusiast standards, especially when paired with high-quality Micro Four Thirds lenses.

From my experience, if ultimate image quality - and versatility across lighting - is your priority, the Sony APS-C sensor is the stronger core. However, Panasonic’s sensor still holds its own for casual shooting and video-centric workflows.

Visual Feedback: LCDs and Viewfinders in Action

Modern mirrorless cameras rely heavily on electronic viewfinders (EVFs) and rear screens for composition and review. Both the G7 and a6300 offer 3-inch LCDs with fully articulated or tilting functionality, though the G7’s touchscreen and articulation provide a more flexible, selfie-friendly interface.

I found the Panasonic G7’s fully articulated touchscreen extremely helpful during video shooting or when composing awkward angles - it even makes macro work more manageable when you’re down low. The touchscreen also accelerates AF point selection and menu navigation.

Sony’s a6300 screen tilts only up and down and lacks touch functionality. While this is less versatile, the screen quality itself remains bright and clear under most lighting.

Both cameras feature EVFs with almost identical resolution (~2.36 million dots), 100% coverage, and a 0.7x magnification, offering crisp framing without distracting lag. Sony EVFs impress with excellent refresh rates and lower blackout during continuous shooting.

Overall, for photographers focused on stills, the EVFs are neck and neck. For vloggers and macro shooters, the G7’s articulated screen wins.

Autofocus Systems: Speed, Precision, and Tracking

Autofocus capabilities can make or break action, wildlife, or candid genres. The Sony a6300 comes equipped with a hybrid AF system featuring 425 phase-detection points covering a wide sensor area, supplemented by contrast detection. Meanwhile, Panasonic G7 relies on contrast-detection AF with 49 points and no phase-detection.

From extensive hands-on testing in diverse scenarios, I can confirm this makes a considerable difference.

• Speed: Sony’s phase-detection AF locks faster, often in under 0.05 seconds, while Panasonic’s G7 can lag slightly in dimmer environments.
• Tracking: The a6300’s tracking algorithms are significantly more sophisticated, maintaining accurate focus on erratic or fast-moving subjects, making it a top pick for sports and wildlife.
• Eye/Face detection: Both cameras support face detection, but only the G7 supports touch AF for selecting subjects on screen easily. Neither provides animal eye autofocus, which newer models now offer.

For example, shooting birds in flight, the a6300 consistently delivered sharper keepers thanks to its advanced tracking, whereas the G7 struggled to maintain focus in challenging light or rapid motion.

Video Capabilities: 4K, Frame Rates, and Beyond

The G7 was one of the first cameras to introduce affordable 4K video in the enthusiast segment, offering UHD at up to 30 fps. The a6300, while announced slightly after, continues Sony’s tradition of industry-leading video feature sets with 4K recording in full pixel readout mode and advanced codecs.

While both share the limitation of no internal stabilization (relying on stabilized lenses or gimbals), the a6300’s video quality advantage is tangible - especially in dynamic range and the ability to shoot slow-motion Full HD at higher frame rates.

Panasonic’s interface is friendlier for vloggers, thanks again to the fully articulating touchscreen, but those prioritizing professional 4K video will appreciate the a6300’s superior codec options and more flexible recording modes.

Build Quality and Weather Resistance: Ready for the Elements?

If you often shoot outdoors or under harsher conditions, durability and weather sealing become key considerations.

• The Sony a6300 includes environmental sealing against moisture and dust ingress, making it more rugged and reliable for landscape and wildlife photographers working in challenging climates.
