rick_walker Posted May 9, 2004 Share Posted May 9, 2004 Does the filter ring of the Pentax 645 AF 80-160mm 4.5 lens rotate as you focus the lens? Also, does anyone know how the optical design compares to the manual focus version of the lens? Thanks in advance. Link to comment Share on other sites More sharing options...
jose_chang Posted May 10, 2004 Share Posted May 10, 2004 No, It does not rotate when you focus the lens. Since I don't have the manual version I wouldn't know. But I will be interesting to find out. Link to comment Share on other sites More sharing options...
peder_mansson Posted May 10, 2004 Share Posted May 10, 2004 The manual focus 80-160mm lens DOES have a rotating filterring. (It doesn't rotate when zooming in and out, but that's of little value). Link to comment Share on other sites More sharing options...
