----- Original Message ----- From: Mike Ignatiev Subject: 50/1.2 (was Re: Depth of Field Preview)
> Speaking of DOF preview. Playing with my newly acquired 50/1.2, I tried to compare (naturally) how much difference f/1.2 makes wrt f/1.4. To my surprice, it was NONE. Absolutely whatsoever none! I was looking through LX with a new (SG-60?) grid screen and at 1.2 and 1.4 the view was absolutely identical. The diafragm did change, I could see it in the lens, but that was it. > Does anyone have an explanation? Yes, depth of field preview only works for gross differences in DOF. William Robb
