Hello Michael !

Sorry, maybe I wasn't precise enough when I was writing what I would have liked to accomplish with this post. I didn't mean to see the same image shot with two different lenses. And I am not interested in image circle or resolution either.
For me the sense of my post was to be able to see images (landscapes/portraits) shot with both focal lengths, to see what kind of feel they have. If there is no difference between 135 and 150, as someone suggests, then there is no difference between a 150 and a 180, and then there's no difference either between a 180 and a 210 either !
