Hi Paul, If you are looking at the equivalent diagonal angle of view then for a: 35mm frame (24mm x 36mm) a 50mm FL lens = 46.79� 645 frame (56mm X 41.5mm) a 86.7mm FL lens = 46.78� 67 frame (55mm X 70mm) a 106.6mm FL lens = 46.77� Cheers, Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://members.ozemail.com.au/~distudio/publications.html - This message is from the Pentax-Discuss Mail List.
