« Inside Straight: Like a Leica | Main | From The Keppler Files: November, 1966 »

December 05, 2007



Mr. Keppler’s comments are a time machine. This was still an interesting issue in 1991, but with the explosion of digital SLR cameras, the use for a single-focal-length "normal" lens as a primary lens is somewhat antiquated. And what IS a "normal" focal length? Depends on the camera and its associated "lens factor".

P.S. I do own a 50mm f1.8 lens for my film SLR, which I bought with the camera XX years ago. For my DSLR, it makes a nice fast short telephoto.


Well then in that case get a 30mm which is about 50mm on a 1.6x body...

A 50mm lens on a 35mm camera will always be *the* normal lens, to get a normal lens on a crop dSLR just get a lens with an equivalent view of 50mm


I have been shooting long enough to remember (as I'm sure the late Mr. Keppler would) when certain camera manufacturers listed 55mm and 58mm lenses as "normal" (for 35mm film).

DSLRs can range from no conversion factor for the top-end Canons to 2x for the "four-thirds system" cameras from Olympus. There is no one right answer. Most DLSR kits ship with an 18-50mm or thereabouts zoom as standard equipment.
