Fuji GFX Lens on Canon RF

[Ryan Chernin]

An adapter to use GFX lenses on an RF mount doesn't currently exist, as far as I'm aware. However, Fuji makes some REALLY nice medium format glass that would definitely cover a Monstro and Raptor sensor.

Would it even be possible to adapt? Fuji GFX flange distance is 26.7mm, Canon RF is 20mm, which is pretty close... I'm not totally convinced a roughly quarter-inch thick adapter would be particularly sturdy or effective, but hey I'm no engineer.

What do y'all think?

A dumb adaptor is in theory thinkable, but the lenses need power and probably communication to control the aperture and focus, these are not mechanical on them, not to mention OIS and focus.

So things get complicated. A proper GF-mount would be dope, but I can also see some form of re-housing or lens-modification happening at some point.
Also keep in mind, the lenses are great for stills and some video/film-usage, yes, but there is no really complete consistent set for cinematic use. Zooms are also not par-focal and there is focus shit here and there. I love mine, but they are made for stills.

And lets face it, this would be for a VERY small niche.

I'm all for the Fuji GFX cameras, they're a really cool looking option but until they have 8K video, I can't consider one as an option even though the system more than satisfies for stills use. A similar situation to yours is the Sony E adapters for the Nikon Z mount, very thin adapter but it does the trick! The only thing is if it might be too thin of an adapter for GFX to RF, if so then it becomes a liability in case of bending or sensor interference. I'm glad at the general adoption of mirrorless mounts but it's going to take some time to see which one tops out above the others like EF did but with Nikon F cutting a close second. I wonder if replaceable fronts on cameras like the Ursa 12K and Kinefinity will be the way to go moving forward so as to have multiple mirrorless mount options depending on which front you go with along with appropriate shims or maybe some sort of bellows-like sensor service adjustment mechanism. Until some sort of development happens with camera design, the only thing with adapters is whether somebody makes something or not as was the case with my quest to find a custom Leica M front or adapter for the Ursa 12K which turned up a lot of dead ends.

Ive got a set of Hasselblad FE's that are all manual and only have the focus and iris in the lens. Super amazing look on Monstro and Raptor. Also have a tilt shift adapter that goes with these and because of the coverage its pretty sick what you can create with these..
