Hello all... David, welcome to the list. Shel, although the manual does cover this feature, it's a little cryptic. The theory and application aren't really covered in the manual, and the text has probably gone through a Japanese-to-English translation anyway.
David, I'm sure I'll mangle the explanation, but others will come to your rescue to straighten things out. Basically, your DOF preview button stops the lens aperture down to whatever aperture will be used when the shutter is released. This is useful when you need to determine how much depth your image will have when the picture is taken, and how much light will be striking the film. In order to give you the brightest viewfinder image, the camera holds the lens aperture at its widest until the shutter is released, then automagically stops the lens down just before the shutter is lifted. The camera does this at all times, including Program (P) and Shutter Priority (Tv) modes, and when you select the aperture (Aperture Priority mode, Av) on the lens. t On 12/28/01 8:11 AM, Shel Belinkoff wrote: > Welcome to the list. > > Since the camera is new, isn't there an instruction manual with it that > can explain how the DOF preview works?
