Pentax in fact has made two different 35mm f3.5's and a 33-55mm f4.5 zoom previously for 645. 35mm's are the normal ultra-wide for 645 format. Mamiya and Hasselblad currently both offer 28mm's which replace a 35 handily on the 1.3x crop sensors (Mamiya's 28 covers 645, Hassy's does not and relies on software correction for distortion correction)
Looking at the design, which clearly has a filter holder, I'd expect something wider than 28mm, so I'd say either a 24mm fisheye or a 20-25mm rectilinear prime. -Adam On Thu, Mar 11, 2010 at 3:08 PM, CheekyGeek <[email protected]> wrote: > Not sure, but the widest medium format lens that I was aware of > previously was the Bronica 40mm f4. > This lens is f4, and Pentax had previously made a 45-85mm f4.5 zoom > for the 645N. > So I'm guessing something in the 30-35mm range for the digital 645 > format (since it doesn't have to cover a full 6x6). > No idea what the knob's for. > > -- > PDML Pentax-Discuss Mail List > [email protected] > http://pdml.net/mailman/listinfo/pdml_pdml.net > to UNSUBSCRIBE from the PDML, please visit the link directly above and follow > the directions. > -- M.
