Hi Shel: I've had such lens for less than a week and I am still shooting some slides to see how it performs. So far, I only can comment on my impressions (preliminary) about the construction of this lens. It is big, heavy, and people don't like to see it pointing towards their noses (they would dislike it even more if they saw how they look through the viewfinder). It weighs 430 gr. and there isn't a screw for filters in the front part of the lens. Focusing is smooth, the aperture ring goes in half stops from 2.5 to f:16, and a full stop from 16 to 22. Unfortunately the focusing ring is wider than in Pentax lenses and this means that you can't see the aperture in the periscope window in the MX viewfinder. It comes with three rear mount filters: UV, orange and green. It is not necessary to screw one of them to get infinity focus, and this is a good thing, as they interfere with the movement of the mirror in three of my Pentaxes: MX, MZ-5 and MZ-S. This doesn't happen in the Z-1 or SFX (bigger mirror chambers?). I will write a more detailed comment when I have the slides developed. ------------------------------------------------------------------ Carlos Royo [EMAIL PROTECTED] Zaragoza (Aragon) - Spain ------------------------------------------------------------------ - This message is from the Pentax-Discuss Mail List.
