Originally posted by IgorZ I heard two reviewers say that old lenses are not going to be sharp on K-1, but I don't know authoritative they are, and whether they spoke from experience, or theory
How is there any sense to that statement? Please just look at what they are saying. "old lenses are not going to be sharp on the k-1". Does the lens magically change because you put it on a newer camera? Of course not. The lens will be just as 'sharp' on the k-1 as it ever was. On film, on the k-x, on the k-5, on the k-3. How this nonsense keeps getting perpetuated is beyond me.
Every time a new sensor is released it is pronounced that "old lenses will not be sharp anymore". And each time photographers just go out and keep taking sharp pictures with them.
