Well, that was a surprise. We knew Irix had a fast medium format lens on the way because they released a teaser a couple of days ago. But it turned out to be faster than the teaser suggested – only hinting at an aperture of at least f/2.8. We thought it was going to be something new and shiny, but it seems that all they’ve done is stick a GFX mount on their existing 45mm f/1.4.
This isn’t a bad thing, however, as it’s still the fastest aperture native mount lens available for the Fujifilm GFX system. Although it does raise some questions. Like, if the 45mm f/1.4 had such a large image projection circle, how come the original version for DSLRs couldn’t offer any kind of tilt-shift capability? And isn’t it cheaper to just get a DSLR version and a lens adapter for GFX?
