Mitakon launches 85mm f/1,2 for Fuji GFX

Considering all of the third party lens makers flocking to the E-mount, I was wondering when we would start to see 3rd party products for the GFX/X1D. This particular lens doesn't plug much of a hole in the FOV range available already but it should silence the criticism about the lack of fast lenses. I might buy this thing just to support the notion there is a market for Fuji G Alt lenses.

Laowa 17mm F4 GFX Zero-D

Third party options for the mirrorless medium format Fujifilm GFX camera are still somewhat limited—at least compared to more popular mounts like Sony FE, not to mention Canon EF or Nikon F. So it was a nice surprise to see Venus Optics release the 17mm F4 GFX Zero-D.

I have the 50 mm f/0.95 FF lens. I'm still trying to figure out what, if anything, to use it on.

how does 17mm x 1.5 = 13mm

Everyone just sees an article and blindly copy/pastes info with no thought.

This 17mm lens is NOT a 13mm FF equiv.

Vertically, it's a 17/(33/24) = 12.36 mm equiv.

Horizontaly, it's a 17/(44/36) = 13.09 mm equiv.

Sounds close enough for government work.

Then there are those who run their mouths without knowing what they are talking about. Where did you come up with the 1.5x factor? Jim's calculation is likely more accurate but I like 17x.79 = what?
 
On the link, format compatibility says full frame, so is it just a full frame lens with a G mount that covers the MF sensor?

I can see how it might read that way. You'd think the company would make an effort to note the vignetting if this were only a FF lens with a G mount. Don't know if it means anything but the G-mount version costs $50 more maybe for the extra glass.
