Originally posted by aesdj Hi. Got a Samsung GX10 that is a Kaf2 mount and I'm thinking of ungrading to the K3ii as I believe it is better for sport/action shots. My question is will my Kaf2 lens fit this body and will all the features work both on the lenses and body? Thanks Jason.
Yes, all K-mount lenses will work on the K-3ii camera.
