Part of my reply below was just WRONG. The 35mm equiv. is not printed on the front of the lens. That was the filter size. My basic multiplication tables have failed me once again.
Still, the descriptions refer to the 35mm equiv. and Pentax and reviews all note the 35mm equiv. and crop factor (doubtless for the reasons I gave).
