Guy, interesting recommendations. I wish I still had the back strength to use the combinations you suggest. I've been lucky to get good results with the Leica C-90 in a lens size which I can actually carry in the front pocket of my camera bag! I would very much like to own a 90-APO again but realistically both in money and size terms it ain't going to happen.
Obviously, this is cropped but hey, why give us a humoungus sensor if it ain't for cropping?
