Big Sensor, Small Limits: GFX100RF vs X100VI

Two cameras with very different ambitions are compared head to head: the Fujifilm GFX100RF and the Fujifilm X100VI. You’ll see whether extreme resolution and a bigger sensor change your results when you actually walk around and shoot.

Coming to you from Tony and Chelsea Northrup, this detailed video breaks down what happens when you pair a medium format, fixed-lens powerhouse against a compact APS-C classic. The Fujifilm GFX100RF is a 102-megapixel medium format camera with a 35mm f/4 lens (a 28mm full frame equivalent), a leaf shutter, and a built-in ND filter that cuts four stops of light. The aluminum body weighs about a pound and a half, giving it a surprising lightness for its size. Its minimalist design skips a built-in flash but keeps Fuji’s signature tactile appeal: metal dials that click, a smooth aperture ring, and a solid feel throughout. It has dual card slots, a tilting touchscreen, subject detection autofocus, and 4K 30p video with a headphone jack. What it doesn’t have is in-body image stabilization.

The Fujifilm X100VI enters as the smaller, faster, and far less expensive challenger at about one-third of the GFX’s price. It brings a 40-megapixel APS-C sensor, an optical viewfinder, a built-in flash, and improved video specs: 6K 30p and 4K 60p. It lacks a headphone jack but includes in-body stabilization, something the GFX doesn’t. Autofocus comparisons tell an interesting story. The GFX tracks subjects well enough for slow movement, handling a six-frames-per-second burst that keeps up with a person walking toward the camera. The X100VI can shoot up to 20 frames per second (cropped) but often sacrifices focus accuracy at the top end. Dialing down to eight frames per second yields a more consistent hit rate.

The GFX100RF dominates in pure image quality. Its 102-megapixel files show striking detail, deeper tones, and more contrast when compared on test charts and real-world scenes. Cropping tests reveal one of its biggest advantages: even when cropped in to mimic 70mm or 85mm framing, you still end up with 25 or 17 megapixels respectively—plenty for large prints or tight framing without losing sharpness. The X100VI, while impressive for its class, softens in low light and loses fine detail faster under heavy cropping.

But the video doesn’t stop at technicals. They tested viewer perception by posting two shots of their dog (one from each camera) on Instagram. Despite the GFX’s higher resolution, most people preferred the X100VI image because of expression and charm. That experiment shows how the “fun factor” and storytelling can outweigh specs. Both cameras offer that tactile joy: clicky dials, elegant menus, and Fuji’s beautiful film simulations that make it easy to send JPEGs straight to your phone.

The GFX100RF fits users chasing the highest resolution, studio-level files, or heavy cropping power. The X100VI suits those who value portability, stabilization, and strong video in a camera that’s easy to carry everywhere. The video also briefly compares the GFX’s position to fixed-lens luxury models like the Leica Q series and the Sony RX1R III, showing how Fuji’s design fits within that premium niche.
