The Canon EOS R5 Mark II (Mars Score 81.8) narrowly edges out the Fujifilm GFX 100 II (81.7) — a virtual tie between a full-frame speed-oriented body and a medium-format resolution monster. At $4,299 versus $7,499, the R5 Mark II is also $3,200 cheaper, which matters alongside the spec trade-offs below.
Resolution is a landslide for Fujifilm
The GFX 100 II's 102 MP medium-format sensor dwarfs the R5 Mark II's 45 MP full-frame sensor — more than double the pixel count, plus a physically larger sensor that generally means more dynamic range and tonal headroom per pixel on top of the resolution gap itself. If your work is studio, product, landscape, or anything where you crop hard or print large, this is the single biggest number in this comparison and it favors the GFX 100 II decisively.
Autofocus coverage and weight strongly favor Canon
The R5 Mark II's 1,053 AF points more than double the GFX 100 II's 425 — a real gap for tracking fast or unpredictable subjects across more of the frame. The R5 Mark II is also substantially lighter at 746 g versus the GFX 100 II's 1,030 g, a nearly 300 g difference that adds up over a full shooting day, especially once you add medium-format glass to the GFX system.
ISO ceiling favors Canon too
The R5 Mark II lists a 102,400 max ISO against the GFX 100 II's 12,800 — an 8x gap. Higher resolution and larger sensor area on the Fujifilm side trade off against per-pixel light-gathering at that pixel density, which is consistent with Canon's much higher ISO ceiling. If you shoot in low light without strobes, that's a real practical edge for the R5 Mark II.
Video and shared strengths are matched
Both cameras top out at 8K video with RAW output and a log profile — an exact tie on video ceiling. Both also list in-body stabilization, dual card slots, full weather sealing, and eye-AF, so the baseline flagship feature set is fully met by both.
Why these two are essentially tied
Mars Score for cameras is built from sensor specs (35% — megapixels and sensor size), video (25% — max video resolution), autofocus (20% — AF point count), and body/design (20% — weight). Both cameras tie on video (both 8K). The GFX 100 II wins the heaviest-weighted group, sensor, decisively on both its higher megapixel count and larger sensor format. The R5 Mark II wins autofocus and design just as decisively — more AF points, less weight. Those two roughly-equal-sized wins on Canon's side very nearly cancel out Fujifilm's single big win in the heaviest group, which is why the final scores land a tenth of a point apart.
Who should buy which
- Fujifilm GFX 100 II — if your priority is maximum resolution and dynamic range for studio, product, or landscape work, and you're willing to carry the extra weight and pay the premium for medium-format glass.
- Canon EOS R5 Mark II — if you shoot fast-moving or unpredictable subjects (sports, wildlife, events), want a lighter body for long days, and would rather have autofocus coverage and high-ISO headroom than an extra 57 megapixels.
- Either, if you're already invested — the mount and lens collection you already own is a bigger practical factor than these spec deltas for most photographers switching within a system.
What we're not claiming
This comparison is built entirely from the manufacturer-published specifications in our catalog — sensor size, megapixels, ISO ceiling, AF point count, weight, and feature flags — plus general, well-established reasoning about what those spec categories typically mean in practice. We have not shot with either camera or run a side-by-side image-quality test. If you need lab-measured autofocus tracking percentages or noise-floor charts, look to a dedicated photography review outlet.
