One of the largest factors distinguishing these cameras is their sensor size and resultant image quality.

Canon EOS R: Full-Frame Powerhouse

The EOS R sports a 30MP full-frame CMOS sensor measuring 36x24mm, which affords exceptional detail resolution (max 6720x4480) and superb performance in low light thanks to its wide native ISO range (100–40,000 boosted to 102,400).

The sensor’s 5655-pixel Dual Pixel CMOS AF system provides fast and accurate phase-detection autofocus for stills and video alike. Canon also preserves skin tones naturally and renders pleasing color depth (measured DxO color depth 24.5 bits), making it a portrait photographer’s delight.

Panasonic G100: Micro Four Thirds Efficiency

The G100 features a 20MP Four Thirds sensor (17.3×13 mm), which is significantly smaller, with a crop factor of 2.1x. This sensor captures images at a max resolution of 5184x3888 and supports a native ISO range up to 25,600.

While the Micro Four Thirds sensor can’t compete with full-frame in terms of base image quality or dynamic range, it still delivers sharp, well-saturated photos with respectable noise performance at moderate ISOs. Panasonic’s contrast-detection AF with 49 focus points is competent but slower to lock than Canon’s phase-detect system.

Real-World Image Quality

In practice, the EOS R produces images with richer tonality and greater ability to recover shadows and highlights, great for landscapes and studio portraits requiring fine gradation. The G100 yields cleaner JPEGs at low ISO but struggles somewhat in darker scenes without additional lighting.

Shooting Experience: Autofocus, Speed, and Handling

How a camera performs in the heat of action can make or break your shooting session.

Autofocus Performance

• Canon EOS R: The massive 5655-point Dual Pixel CMOS AF system excels at accurate, snappy focus and tracking across the frame, including face detection. Although it lacks specialized animal eye AF, its human eye detection works well for portraits. This is critical for wildlife and sports photographers needing reliable continuous-focus performance.

• Panasonic G100: It uses 49 contrast-detection points, effectively slower and more prone to hunting under low contrast. Suitable for casual subjects and video selfies, but less ideal for fast-paced sports or wildlife.

Burst Shooting and Shutter

• EOS R: 8 fps continuous shooting with a maximum shutter speed of 1/8000s supports freezing fast action.
• G100: Slightly faster burst at 10 fps, but max shutter speed only 1/500s on mechanical shutter (1/16000s silent electronic shutter available). This may limit freezing extreme action but good enough for most hobbyists.

Viewfinder and Screen

Both cameras offer perfectly viable electronic viewfinders with ~3690 pixel resolution and 100% coverage, with Canon’s EVF at 0.76x magnification feeling a touch more immersive than Panasonic’s 0.73x.

The EOS R’s larger, 3.2-inch fully-articulated touchscreen with higher resolution (2100k dots) compared to the G100’s 3-inch 1.84m-dot screen enhances in-field reviewing and menu navigation.
