I know you're probably still recovering from your cologne experience, but let me ask you about the Pentax.
you wrote, that you are happy with it. I have seen a couple of pics online in reviews and first looks, and I can't shake the impression that some lenses for it are not really good. when making the move to MF, I expect to have edge to edge sharpness, as this is one thing that is really hard to get with the D810 and nikon lenses and I have tested and own about 10 of them, all worldclass on lower res bodies.
I am only interested in a very good standard, a macro for portraits and a wide(28mm~FF).
is there anything in the pentax line that you consider good enough all the way to the corners?
wishing you a colourful fall and thanks for your time
cheers from NZ
