Just wonder if you guys have had experience with either Contax G 90mm F2.8 or the Leica Summarit 90mm F2.4/2.5 ? I will be using it on the A7r.
I already have a decent m adaptor. obviously the contax is much cheaper, but by the time i get a decent adapter, then the cost is not too far off a secondhand summarit F2.5.
I mainly want to use it for color landscape i.e. close to infinity, and max aperture is not too much of a concern. thanks.
