The widest rectilinear full-frame lenses on Canon and Nikon's websites are 14mm, and this (undated) Luminous Landscape article says the widest overall is a 12mm Voigtländer (for rangefinder, not SLR): http://www.luminous-landscape.com/reviews/lenses/ultrawide.shtml The 10-20mm APS-C zooms aren't quite as wide as the 14mm full-frame lenses, but it's pretty close. -- 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.
