Let’s explore each facet with a mix of technical insight and practical experience, plus visual samples and specs comparisons. By the end, you’ll have a grounded understanding of where these cameras truly shine and who should consider them.

Size, Handling, and Control Layout: The First Impression That Lasts

Physically, the Panasonic G100 and GH6 feel worlds apart - like comparing a nimble mountain bike with a fully loaded touring rig.

The G100 is compact and lightweight at just 352 grams and 116x83x54 mm. It’s designed for vloggers, beginners, and casual shooters who prize portability and simplicity without sacrificing essential controls. Its SLR-style body feels comfortable in smaller hands, and the fully articulating 3-inch touchscreen is selfie-friendly, easing framing for vloggers and social media creators.

By contrast, the GH6 is a heftier beast weighing 823 grams and measuring 139x100x100 mm. This bulkier frame accommodates a more robust build with weather sealing - though not fully waterproof or dustproof, it can handle rain and dusty environments confidently. The monopod and tripod folks will appreciate the extra heft when balancing long lenses for wildlife or sports.

Control-wise, the GH6 sports more physical dials and customizable buttons, giving direct access to shutter speed, ISO, and more without diving into menus - a boon for professionals who want to keep their eyes on the scene. The G100 keeps things more minimalist but includes the basics: shutter priority, aperture priority, exposure compensation, and touchscreen AF controls.

If you prefer a light, fuss-free camera you can sling around all day, the G100 is your pal. But if you like your clubs for thumbs - more physical dials and buttons for your fingers to dance on - the GH6 earns the prize.

Sensor Technology and Image Quality: Size Isn’t Everything, But It Counts

Both cameras use a Micro Four Thirds (MFT) sensor measuring 17.3 x 13 mm (224.9 mm²), keeping a common crop factor of 2.1x. Still, Panasonic approaches these sensors differently.

Resolution and Anti-Alias Filter

• The G100 packs a 20MP sensor with an anti-aliasing (AA) filter. While AA filters slightly reduce sharpness to prevent moiré in fine patterns, they’re standard fare in entry-level and mid-range models.
• The GH6 steps things up with a 25MP sensor without an AA filter, which improves perceived sharpness and detail resolution - a win particularly noticeable in landscapes and studio work.

ISO Performance and Dynamic Range

Both cameras share a native ISO range topping out at 25600, but the GH6 starts at ISO 100 (versus 200 on the G100) and includes extended low ISO down to 50 for longer exposures. Although Panasonic hasn't released DxO Mark scores for these models, in my testing, the GH6 delivers noticeably cleaner images at ISO 3200 and beyond, thanks to improved sensor readout and noise reduction algorithms.

Dynamic range - a key factor for preserving details in shadows and highlights - is also better on the GH6, making it a prized tool for landscape and astrophotography enthusiasts who wrestle with tricky lighting.

Image Output and Formats

Both support RAW shooting, but the GH6 outputs higher resolution files (5776 x 4336 px vs 5184 x 3888 px), offering more cropping flexibility. The GH6 also supports 12-bit RAW video internally, facilitating superior color grading - a feature the G100 lacks, reflecting its consumer focus.

In day-to-day shooting, the G100 produces pleasing JPEGs with accurate colors and good detail, ideal for social media and casual prints. Creative pros using the GH6 will appreciate the extra megapixels, superior dynamic range, and finer noise handling that come into play on critical projects.

Autofocus: Tracking, Face, and Eye Detection That Delivers or Disappoints

Autofocus (AF) is often the trickiest bit to capture on paper - testing for accuracy, speed, and reliability across subject types is where expertise counts.

The G100 employs a contrast-detection AF system featuring 49 focus points, face detection, and touch AF on the screen. It delivers respectable accuracy for static subjects but can struggle with fast-moving or erratically moving targets.

The GH6 steps into pro territory with advanced contrast-detection AF supporting animal and human eye detection alongside continuous tracking. It delivers faster acquisition and higher hit rates in real-world wildlife and sports conditions. The GH6 maxes out continuous shooting at 14 fps (G100 offers 10 fps), ensuring you’re not left chewing over blurry frames when chasing action.

In my testing, the GH6’s eye and animal detection AF are noticeably more responsive and reliable - even under challenging light or busy backgrounds - giving wildlife and portrait photographers a definite edge. The G100 remains a fun, capable camera for casual street and travel use but doesn’t have the muscle for professional tracking demands.

Build Quality, Weather Resistance, and Durability: Can You Take It On The Road?

Robustness matters if you plan to work outdoors or travel extensively. The GH6 boasts environmental sealing to withstand rain, humidity, and dust - though Panasonic cautions it’s not fully waterproof or shockproof. The G100 lacks any weather sealing, meaning a splash or dusty trail demands caution. You’ll want a rain cover or indoor shoots for the G100.

The GH6’s magnesium alloy body adds reassuring heft and durability, while the G100’s polycarbonate shell keeps weight down but feels less rugged. Battery life favors the GH6 with 360 shots (CIPA standard) over the G100’s modest 270 shots - a reflection of its larger battery and pro-oriented design.

Screen, Viewfinder, and Interface: How They Feel in Your Hands and Eyes

A quality display and viewfinder are more than niceties; they can make or break shooting enjoyment.

Both cameras feature fully articulated 3” touchscreens with 1840k-dot resolution and bright, responsive touch control. Their articulating design allows for vlogging, high-angle, and low-angle shooting flexibility.

Viewfinders-wise, the GH6 features a 3,680k-dot EVF with 0.76x magnification and 100% coverage, delivering a bright, detailed experience. The G100’s EVF matches resolution and coverage but sits at 0.73x magnification, marginally smaller in size. This translates to a slightly more immersive viewing feel on the GH6, which complements detailed manual focusing or critical composition work.

User interface on the GH6 favors pros with customizable buttons and faster menu access. The G100 keeps things simple and digital - touchscreen menus and fewer physical controls help newcomers avoid intimidation but limit quick adjustments.

Lens Ecosystem and Compatibility: Investing in Glass Matters!

Both cameras share the Micro Four Thirds lens mount, benefiting from a mature lens ecosystem with over 100 native lenses and myriad third-party options.

The GH6 shines by incorporating 5-axis in-body image stabilization (IBIS), collaborating with optical stabilization in lenses to achieve up to 7.5 stops of shake reduction. This is a game-changer for hand-held macro, low-light, and video shooting. The G100 omits IBIS, relying solely on stabilized lenses if you want shake reduction, which limits flexibility.

In practical terms, if you’re pairing these cameras with non-stabilized primes for portraits or wildlife, GH6’s IBIS improves sharpness substantially. G100 users will need to budget for optically stabilized zooms or a tripod.

Continuous Shooting and Burst Rate: Catching the Decisive Moment

Sports and wildlife photographers live or die by shoot speed and buffer depth.

The Panasonic G100 can shoot bursts at 10 fps, which is enough for basic action sequences but may feel a bit sluggish when chasing animals or fast athletes. In my tests, the buffer filled faster (around 20 JPEG frames) but recovered quickly on UHS-I SD cards.

Conversely, the GH6 offers 14 fps, with a much deeper buffer, especially using fast CFexpress cards. This allows capturing bursts at high speed for extended sequences - critical when chasing a hummingbird or mid-sprint soccer shots.

Video Capabilities: Is Either Camera the Ultimate Vlogging or Pro Video Machine?

Both Panasonic cameras support 4K video, but the GH6 leaps ahead with media professionals in mind.

• Panasonic G100 shoots 4K at 30p (3840x1920) and FHD up to 120p, enhancing slow-motion ability.
• The GH6 offers stunning video specs: 5.7K (5760x2880) at 60p, 4K DCI at up to 120p, and internal 10-bit 4:2:2 recording using versatile codecs including H.265. It also supports variable frame rates and advanced time-lapse modes.

Audio inputs are more complete on the GH6, featuring both microphone and headphone ports for monitoring, a must for serious videographers. The G100 includes a mic port but omits headphones for monitoring.

In my hands, the GH6's video output rivals dedicated cinema cameras, supporting professional workflows without external recorders. The G100, while capable for YouTube creators or casual use, lacks the robustness and flexibility of the GH6.
