(etal A little known problem sometime arises with wide apertures & the resulting shallow depth of focus due to the flange to film plane distance being off more than 1/10 of a mm (that's only 1/250 of an inch). I think a heavy squeezing of a zinc body can cause this & for critical work, you can test the d.f. your- self with just a few test exposures or have a technician use a depth gauge if you focus is off even slightly. I have taken c.u. pix at f:1.0 where one eye was in focus & the other out, so we are talking about a very close tolerance. ******************************Marvin Moss************************************* << Since then I have got the f.1.0 version and feel that I got the one that suited my needs best. My desire was to get maximum speed and maximum background blur in a 50mm lens, and f1.4 really wasn't doing it for me. F1.0 seems a really good reason for getting the newer version! It is so nice to be able to use Kodachrome 200 handheld when others are using flash, or a tripod, or are watching me and wondering what the hell I'm doing with a camera in the dark. For someone such as myself who always likes to take pictures where the light is low, this lens is a gift. I haven't had it long but I know this lens had my name on it. >>
