About standard focal length for the *Ist D. Is it true, that a "normal" lens for the *ist D, with a CCD of 23.5 x 15.7 mm is equal to the diagonal of this rectangular square? If yes, the standard focal length should be 28,3mm. This calculation (Phythagoras) gives us a 43.3 mm standard focal length for the 24x36mm format. This will result in a factor (35mm film/CCD) of 1.53. All the best
