I'm seriously considering this lens, but I need your help. I have a KP and K-1 and am interested in comparing how well the 20-40 performs on each camera. If anyone has a HD DA 20-40, KP and a K-1 and is happy to shoot the 20-40 on the K-1 at 3 lengths (24mm, 30mm and 34mm) and each shot taken wide open and also f8, and then also do the same with the KP at close to/equivalent FoV ranges and apertures and drop those RAWs somewhere, I would be forever in their debt
The 20-40 on the KP gives an approximation of 30-60mm on FF, I'm missing something around 24mm with AF for the K-1 hence that is an attractive prospect. I'm not sure I can justify the price tag of the HD DA 20-40 for the KP only, but if it really does well at 24mm on the K-1 then this might be the deal sealer. So really... the most important shots are RAW files at 24mm on the K-1 at varying apertures.
TIA!
