Takes a second. Interesting point re macro work, as indeed others have said also. The problem is that if I look down a viewfinder stopped down to (say) f/22 and activate DOF preview, the screen goes very dark. Fine you say, let your eyes adjust. I keep staring down this black hole waiting for something to happen - but it don't! The only way I can determine -briefly- a bit of DOF is by releasing and re-engaging (love that word) the DOF preview button quickly, which I'm sure makes a mockery of it's intended use. Lens scales and charts and tables show the area behind and in front of the focus point that will be renedered in focus at a given aperture. Beyond or in front of those distances, it gets soft. Sort of a 'safe area' if you like. All I'm saying is that, for me, calculating distance works much better. What I'm asking is, for those who use the DOF preview TTL method, - - why? Thanks for taking the time to explain and hang a loogy ;-) Cot ____________________________________ Free UK Macintosh Classified Ads at http://www.macads.co.uk/ ____________________________________ Oh, swipe me!
