Quote:I don't recall on the K-m and K-x I had before if there was any AFMA possible, but the K-5 clearly is upper class Pentax. Are the Pentax lenses recognised differently? Anyway, I had some time consuming support queries with the bodies and a Tamron 17-50/2.8 and am happy to got rid of all that. On the Nikon side, however, there's AFMA from D7000 and higher and I guess, up to 20 lenses are supported.Pentax lenses are fully recognized, Sigma seem to fit into categories, for example, my Sigma 50-150mm F2.8 posts itself as the 70-200 F2.8, other zooms just show the focal length used. I have read around that Pentax won't allow third party manufacturers the use of their full codings, so when it's a question of lens IDs, AF adjustments can get exchanged. Keeping a list is therefore beneficial!
