Originally posted by Docrwm Don't want to be one of those people but the lens itself seems to be marked 135/2.2 not 2.0. In looking through the online info it seems its different based on the mount.
I think that's T2.2, F2.0. T2.2 is for cine versions, F2.0 is for still photo versions. Of course both can be used for both, but the Cine version has T stops instead of F stops, a different focus ring for follow focus, and de-clicked aperture ring.
The lens will come in K-mount, and feature A-setting on aperture ring. But it will be manual focus only (of course, with Pentax cameras you can use catch in focus to get something similar to AF. For portraiture, it might be all you need)
I'm glad this lens is coming out. Samyang fills a lot of holes in the Pentax lineup this way!
