Interesting website, nice to read about the pentax camera history and others.
Hi, You are quite right. The vignetting disappears at 22, so it is usable from there on, but the maximum never exceeds 45. Thank you!I will correct it. Bosse
Hi Eric,I don't understand your phrase: "Recommended as a 22-60 wide angel on K-1, and as 16-45 on K-3 II." The focal length range remains the same.
Hi,Thanks for the comment.But the page actually states that the FT-1 was following the FS-1, worlds first camera with a built-in motor.(Under the last photo.)
