I didn't really see any topics going over all the lens choices available for this module. Currently I'm using a GRDIII and a Nikon DSLR. I'm contemplating dumping the DSLR and moving to the GXR, but even with the open M format the lenses I really want doesn't seem to be available. I looking for a 35mm eq. lens to use and from what I have seen there is the Voigtlander 25f4 and 21f4(€400) and the Zeiss25f2.8(€1000) they are either to slow or to expensive for me to switch from my SLR Are there any cheaper 24mm f1.4-2.8 used/new available out there that will give me a 35mmfov. GXR voigtlander 15 A12 28mm a(24mm f1.4) And built in viewfinder would make me a very happy photographer.
