Panasonic Lumix G100 vs G85: An Expert Comparison for Serious Enthusiasts and Professionals

Selecting the right Micro Four Thirds (MFT) mirrorless camera can be a daunting task, especially when faced with two seemingly similar models from Panasonic’s well-regarded Lumix lineup - the Panasonic G100 and the Panasonic G85. Both cameras target distinct user niches but overlap significantly in features and price points, leading many photographers to ask: which is the better investment for my photography style and needs?

Having spent extensive hours testing both cameras across diverse scenarios - from intimate portrait sessions and expansive landscapes to fast wildlife chases and bustling street scenes - I aim to provide a deep, practical analysis that cuts through marketing speak. This comparison delves beyond specs to evaluate real-world performance, handling, image quality, and value. Whether you’re an aspiring content creator or seasoned pro looking for a versatile backup, this article will guide you to an informed decision.

First Impressions: Size, Build Quality, and Ergonomics

When unpacking the Panasonic G100 and G85 side-by-side, the first difference you notice is physical presence. The G85 is notably larger and more robust, weighing approximately 505 grams versus the G100’s lighter 352 grams. The G85’s dimensions (128x89x74mm) reflect a sturdier, “professional-ready” body, featuring weather sealing against dust and moisture - a feature absent in the G100 (116x83x54mm and no sealing).

For photographers accustomed to heavier DSLRs or mirrorless bodies, the G85’s grip and button layout provide reassuring solidity. In contrast, the G100 caters to those who prioritize portability without sacrificing too much control, making it an appealing choice for vloggers or travelers who want a lightweight rig.

Looking closer, the G85 sports more physical controls - customizable dials, dedicated ISO and white balance buttons, and a larger grip that enhances handling with heavier lenses. The G100 opts for a simplified layout, leaning on touchscreen interface and a clean design geared toward ease of use rather than tactile feedback. This difference is critical: if you value quick manual adjustments on the fly, the G85 has the edge.

The G85’s environmental sealing also underlines its intention as a reliable tool for outdoor professionals or enthusiasts shooting in unpredictable conditions. The G100 is better suited to indoor, studio, or light travel use where weather protection is less critical.

Sensor Technology and Image Quality: Resolution, Dynamic Range, and High ISO

Both cameras employ a Four Thirds CMOS sensor measuring 17.3x13mm - a smaller form factor than APS-C or full-frame but optimized in this line for mobility and lens compactness. However, Panasonic chose distinct sensor generations and resolutions for each.

• Panasonic G100: 20MP sensor with anti-aliasing filter
• Panasonic G85: 16MP sensor without anti-aliasing filter

The G100’s higher resolution at 20MP theoretically offers more detailed images, beneficial for cropping or large prints. However, the inclusion of an anti-aliasing filter slightly softens detail to prevent moiré. Conversely, the G85 employs no AA filter, yielding crisper images but demands careful lens selection and shooting conditions to avoid artifacts.

In actual testing, I found the G85’s 16MP images surprisingly punchy and sharp - its omission of the AA filter adds a subtle edge in fine detail rendering, particularly with high-quality primes. Meanwhile, the G100’s image output leans toward softer, more natural textures, excellent for portraits where skin tone rendition matters.

When pushed in dynamic range tests, the G85 outperforms the G100, scoring a DxOMark dynamic range of 12.5 stops versus the untested G100. Its sensor handles shadows and highlights more gracefully - crucial for landscapes and high-contrast scenes.

Low-light performance also favors the G85. Despite both cameras’ native ISO ceilings of 25600, the G85’s DxO low-light ISO rating of 656 indicates cleaner noise control and usable higher ISO shots. The G100, with no formal DxO data, shows more visible noise at ISO 3200 and beyond in my trials.

Autofocus Systems: Speed, Accuracy, and Tracking Capabilities

Both cameras feature 49 contrast-detection autofocus points but lack phase-detection systems. Panasonic relies on contrast detection augmented by intelligent algorithms for subject detection, face recognition, and tracking.

I was impressed with the G100’s eye detection AF that proves effective for portraiture and vlogging, locking sharply and consistently on faces even in soft lighting. However, the G85 maintains an edge in continuous autofocus performance, especially for fast-moving subjects like wildlife or sports.

In burst mode, the G100 offers a 10fps continuous shooting rate - slightly faster than the G85’s 9fps. But real-world shooting emphasizes AF tracking quality over raw frame rate, and the G85’s focused AF algorithms kept subjects sharply locked during longer bursts under varied conditions.

Neither model supports animal eye AF, a newer and helpful feature in current cameras, meaning wildlife photographers will rely heavily on lens sharpness and manual skill.

Viewfinder and Rear Screen: Composing and Reviewing Images

Both cameras include 3-inch fully articulating touchscreens, indispensable for vloggers or creative angles, but the experience differs.

The G100 boasts a higher resolution rear screen at 1840k dots, yielding sharper image playback and better touch control responsiveness. This sharp screen enhances menu navigation and live view use, especially for framing complex compositions in bright light.

Its EVF resolution is a crisp 3,680k dots - excellent for electronic viewfinder performance in daylight or low light. The G85’s EVF is weaker at 2,360k dots but still usable.

Additionally, the G85’s articulated screen, while less dense, has a slight advantage in tilt range robustness and weather resistance due to tighter sealing. This makes it more reliable for prolonged outdoor shooting.

In-Body Image Stabilization and Video Performance

One of the starkest differences lies in stabilization.

The Panasonic G85 features a 5-axis sensor-based image stabilization system - one of the earliest implementations in MFT cameras - which delivers up to 4.5 stops of shake correction. This makes handheld shooting, especially video and low-light photography, markedly easier and yields smoother footage and sharper images without relying solely on stabilized lenses.

The Panasonic G100 lacks sensor stabilization, depending instead on lens-based stabilization if available. In practice, this limits handheld shooting flexibility, particularly for longer telephoto shots or slow shutter speeds.

Video capabilities tell an intriguing story:

• Both cameras shoot 4K UHD video at 30p, but the G100 offers a panoramic 3840x1920 “oversampled” mode focused on vlogging and video creators wanting wider framing.
• The G85 provides 4K at a standard 3840x2160 resolution with better codec options (MP4, AVCHD) and a higher bit rate, making it more suited to serious filmmaking.
• Both have a microphone input but no headphone jack for audio monitoring.
• The G100 supports a higher frame rate (1080p at 120fps) for slow-motion effects, ideal for creative video work.

Overall, when video stabilization and codec flexibility are vital, the G85 remains the winner. It’s a “hybrid” mirrorless camera designed for integrated photo and video workflows.

Lens Ecosystem and Compatibility

Both cameras use the Micro Four Thirds mount, granting access to Panasonic’s extensive lens lineup and offerings by Olympus, Sigma, and other manufacturers.

The G100 and G85 share compatibility with over 100 native lenses, from ultra-wide, fast primes to telephoto zooms.

However, because the G85 targets advanced users, it pairs better with premium professional lenses and benefits more from stabilized lenses complimenting its 5-axis IBIS.

The G100 is extremely lens-flexible but shines paired with compact, lighter primes that complement its traveler-friendly design.

Battery Life and Storage

Panasonic rates the G85’s battery life at a respectable 330 shots per charge (CIPA standard), moderately surpassing the G100’s 270 shots. Extended shooting days or remote locations requiring power conservation favor the G85.

Both cameras accept a single SD card (UHS-I support on G100) slot but lack dual slot redundancy - a consideration for professionals needing secure backups.

Wireless Connectivity and Workflow Integration

The G100 includes Bluetooth along with Wi-Fi, enabling quick transfer to smartphones and seamless remote shooting via Panasonic’s mobile app. This is tailored for quick content sharing and vlogging, where immediacy matters.

The G85 lacks Bluetooth but has Wi-Fi. While functional, it’s less streamlined for modern content workflows.
