Originally posted by Blue The current price of the GXR with the macro aps module is $918. That would be reasonable for a k-module that would allow the use of the DA ltd series.
I think it depends. If a K-module would have SR, AF and a screw-drive. If not, a K-r would be so much better
and cheaper ...
Also, the problem of a K-module of course would be that it wouldn't support small wide angle lenses.
Pentax UK writes: "The PENTAX Q features the newly developed Q mount, with a mount diameter shortened to approximately two-thirds of that of the conventional K mount."
I.e., if the K mount was optimzed for 35mm, then the Q mount was optimized for APS-C ... (1/1.53 = 2/3)
Who knows ... maybe, the Q-mount is meant to become a native mount with attachable Leica M-mount and Pentax K-mount APS-C adapters. So, you attach your DA40 with the K-mount adapter, or a native 12mm Q-mount APS-C lens.
