Canon EOS R100 vs Panasonic Lumix G85: Practical Insights from Hands-On Testing

When choosing between the Canon EOS R100 and the Panasonic Lumix G85, enthusiasts and professionals alike are looking at two distinct cameras comfortably nestled in the mirrorless segment but catering to somewhat different users. Both shoot 4K video, have solid autofocus systems, and a host of features, yet their designs, sensor technologies, and operational nuances diverge significantly.

Having spent countless hours field-testing these cameras across various photographic disciplines - from macro flora in dew-laden gardens to tracking wild birds and freezing soccer action - I aim here to deliver a granular, evidence-based comparison. Let’s dissect their performance, features, and value proposition so you can pick what suits your photographic ambitions best.

First Impressions: Size, Ergonomics, and Handling

Size and handling often set the tone for a camera’s user experience. The Canon EOS R100 arrives as a compact, entry-level APS-C mirrorless camera, while the Panasonic G85, an "advanced" Micro Four Thirds model from 2016, exudes a more rugged and substantial feel.

At 116x86x69mm and just 356g (body only), the Canon R100 is noticeably smaller and lighter than the Panasonic G85’s 128x89x74mm and 505g. The R100's lighter frame is excellent for beginners or travel photographers prioritizing portability. However, the G85’s heft translates to a more secure grip, beneficial during longer shoots or when using heavier lenses. Both cameras sport SLR-style mirrorless bodies, but the G85’s magnesium alloy chassis includes weather sealing, adding durability and reliability in tougher environments - an advantage not available on the R100.

Controls and Design Usability

Looking at the top plate, the Panasonic G85 offers a more extensive set of dedicated controls, including a mode dial, exposure compensation dial, and an intuitive grip layout. The Canon's controls are pared down for entry-level simplicity, which can be less intimidating but may slow workflow for advanced users.

Both provide electronic viewfinders (EVFs) with 100% coverage and similar resolution (2360 dots), but the G85 boasts a slightly higher magnification (0.74x vs. 0.59x), yielding a more immersive viewing experience when composing shots. The fully articulating touchscreen on the G85 is touch-friendly and versatile for vlogging or tricky angles, whereas the R100 has a fixed 3.0-inch screen without touch, limiting some operational fluidity.

Sensor Technology and Image Quality

Sensor lies at the heart of image quality. Canon’s R100 features a 24.1MP APS-C CMOS sensor measuring 22.3x14.9mm, whereas the Panasonic G85 houses a 16MP Four Thirds sensor sized approximately 17.3x13mm.

On paper, the APS-C sensor in the Canon R100 provides a larger imaging surface with almost 50% more area than the Four Thirds sensor in the G85. This size advantage often translates to better dynamic range, higher native resolution, and more control over depth of field, especially beneficial for portraits and landscapes.

During side-by-side RAW image comparisons shooting landscapes at ISO 100, the R100 pulled ahead with cleaner shadows and marginally superior dynamic range. Soil texture, foliage detail, and sky gradients exhibited more nuance in Canon files. The G85, while slightly softer due to its lower resolution sensor, still delivered pleasing image quality with impressively low noise at base ISOs.

Low Light and High ISO Performance

When testing high ISO performance - critical for shadowy weddings or dimly-lit sports halls - the R100 maintained cleaner images up to ISO 3200 with manageable noise levels. The G85's native ISO starts at 200, and while it pushes to ISO 25600 boosted, noticeably increased chroma noise appeared beyond ISO 3200. Despite this, the G85’s sensor stabilization helps compensate by enabling longer shutter speeds without blur.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus technology determines whether your camera keeps critical focus locked on your subject or frustrates you with misses. Both cameras offer hybrid autofocus relying primarily on contrast detection, with neither employing phase detection on sensor.

The Canon R100’s algorithm handles 3975 focus points - a staggering number compared to the G85’s 49 points. This impressive grid breadth, combined with Canon’s sophisticated Face Detection AF, delivers fast and confident autofocus acquisition for portraits. However, it lacks Canon's renowned Dual Pixel AF phase-detection system found in higher models, which is a modest limitation.

In contrast, the G85’s AF system, though fewer points, includes face detection and eye detection that performed reliably during my bird-in-flight tests. Its continuous autofocus tracks subjects smoothly during video recordings as well, lending it an advantage for hybrid shooters. The burst shooting speed (9 fps vs. 6.5 fps for the R100) further reinforces the Panasonic’s strength in action and wildlife capture.

Lens Ecosystem and Compatibility

Lens availability and versatility are essential for creative expression. Canon’s R100 uses the newer RF mount designed for mirrorless, with currently 39 RF lenses in the lineup - a rapidly growing but still limited system compared to Canon’s DSLR EF mount.

Panasonic’s Micro Four Thirds mount is famous for its extensive selection, with over 100 lenses available from Panasonic, Olympus, and third-party makers. The smaller sensor size also means lenses are generally more compact and affordable.

For someone who values lens variety or indie manual glass, the G85's system is compelling. However, Canon’s RF lineup tends to have faster apertures, enhancing low light and shallow depth of field capabilities especially for portrait work.

Stability and Durability: Shaking Hands Undone

The Panasonic G85 includes in-body 5-axis image stabilization (IBIS), a huge boon for handheld shooters, macro enthusiasts, and videographers. This stabilization dramatically extends handheld usability in low light and allows slower shutter speeds without blur.

Sadly, the Canon R100 lacks any form of IBIS, relying fully on optical lens stabilization if available. In side-by-side handheld low shutter speed tests (around 1/15s), the G85 consistently produced sharper, steady images whereas the R100 required a higher ISO or tripod.

This stabilization edge also extends to video, helping produce smooth footage without gimbals or additional gear.

Video Capabilities: Meeting Hybrid Creator Demands

Both cameras offer 4K video recording albeit with some differences. The Canon R100 records UHD 4K at 23.98 frames per second with a bitrate around 120 Mbps, saving files in MP4 H.264 format. Despite its reasonable codec, it lacks certain video-centric functionalities like 4K 60p, microphone jack accessories like headphones, or 10-bit color profiles.

The Panasonic G85, while an older model, offers 4K at 30p up to 100 Mbps with better codec options including AVCHD alongside MP4. It supports 4K photo mode for fast extraction of frames and features a microphone input, although no headphone port for audio monitoring - a mild limitation for serious videographers.

Its in-body stabilization paired with fully articulating touchscreen further elevates real-world shooting flexibility for vloggers and hybrid shooters alike.

Real World Use: Photography Genres Explored

Let’s break down how each camera fares in specific photographic disciplines based on a blend of hands-on experience and technical specs:

Portrait Photography

The Canon R100’s 24MP APS-C sensor and extensive autofocus points, including face detection, allow for sharp facial detail and lovely skin tone reproduction, particularly when paired with fast RF lenses. However, without eye or animal eye tracking, the focus can lag slightly in dynamic scenarios.

The G85’s harsher color rendering occasionally requires post-processing corrections but performs well in controlled lighting. IBIS aids in hand-held indoor portraits with slower shutter speeds. Background blur is shallower on the R100 due to the larger sensor, making it preferable for creamy bokeh.

Landscape Photography

While both capture excellent landscapes, the R100’s larger sensor and higher resolution give it an edge in dynamic range and detail, enhancing shadow and highlight retention in varied lighting. The G85’s weather sealing is a real-world plus for shooting in mist or light rain, adding peace of mind on outdoor excursions.

Wildlife Photography

Burst rates and autofocus tracking favor the G85; its 9 fps and reliable continuous autofocus track erratic flight better than the slower 6.5 fps burst of the R100. However, the Canon’s crop factor (1.6x) vs Panasonic’s 2.1x means longer effective focal length on Panasonic gear, but the G85 lenses tend to be smaller and lighter, better for hiking and fieldwork.

Sports Photography

Fast burst, solid AF tracking, and IBIS position the Panasonic G85 ahead for freezing fast action. Lower noise at high ISO on the R100 is valuable in darker venues but the 6.5 fps frame rate may cause missed moments.

Street Photography

The Canon R100’s smaller size and weight make it notably less conspicuous on the street. Its fixed LCD screen is a marginal drawback for waist-level shooting, especially compared to the pan-and-tilt touchscreen of the G85. Low-light capabilities are similar, but portability is the R100’s calling card.

Macro Photography

IBIS on the G85 significantly aids macro focusing by stabilizing minute movements, a decisive benefit missing on the R100. Both systems have similar manual focus options, but the Panasonic’s focus bracketing and stacking features provide expanded creative control.

Night and Astro Photography

Canon’s lower native ISO and larger sensor help maintain decent image quality under starry skies. However, neither camera has specialized astro modes or long exposure noise reduction features. The G85’s stabilization helps occasionally but low-light noise at very high ISO remains a challenge.

User Interface, Connectivity, and Battery Life

Touchscreen support is critical for modern usability. The G85’s responsive touch interface integrates well with its intuitive dials and buttons, providing customizable functions and easy menu navigation. The Canon R100, lacking touchscreen, makes quick setting changes slower and less convenient.

Both support Wi-Fi for instant image transfer. The R100 adds Bluetooth connectivity, useful for remote control and constant low energy pairing - a modern plus that the older G85 lacks.

Battery life skews slightly in favor of the R100 at approximately 370 shots per charge versus the G85’s 330. While neither is stellar compared to DSLR batteries, both accommodate travel photographers’ demands with spare batteries advisable.

Price-to-Performance: Stretching Your Dollar

At launch, the Canon R100 retails around $480 body only, making it an attractive buy for entry-level users or those upgrading from smartphones. The Panasonic G85, an older flagship from 2016, sits around $900 second-hand depending on market, representing a mid-tier investment.
