Hi! That's an odd question I think. I mean, like how much salt do you like in your soup? Well, it depends on salt brand and on soup.
Honestly, I use the DOF preview button if I am going no slower than f/8. Though if there is a lot of light (landscape) I use DOF preview on slower apertures. The rest depends on subject, my mood, the lens, and so on... However my general tendency is towards the slowest possible shutter speed (1/45-1/125 sec) and hence narrower apertures (f/8 and on). But really, it depends on too many factors to give one general answer. --- Boris Liberman www.geocities.com/dunno57 www.photosig.com/viewuser.php?id=38625
