Me too ... 21mm for Street up-close would be great. ;-)
Is there a menu to activate that the GW2 is attached and the scale-focus scales are seen on the screen corresponding to a 21mm?
Unlike putting GW-2 onto GH-2, A12 28mm cannot recognise it because there is no connector. It use conventional step up ring. AF should'nt be a problem. SF can be negligible as you also mentioned the deep dof of 21mm.
This method is a cheaper way to get 21mm f2.8 as compare to CZ's.
