Hi all, I am looking at permanently attaching a 50 mm lens reverse mounted on my bellows - I usually use my FA50f1.4, but I'm starting to get annoyed with taking it apart and putting it back together again. The question I need answered is, as I'm going to dedicate a lens to the bellows, which one would be best for my needs?
I generally shoot with the lens stopped down to f16 or f22 to get the greatest depth of field. My subjects are 3 dimensional, so a flat field of focus is not 100% necessary. My subjects also tend to hide from bright lights, so I can't use extra light to help me focus, and at full extension of the bellows and a 2 times converter between the camera and bellows (7 times magnification to the film), any extra light is a bonus. I'll probably end up with a K or M f1.4 or a K f1.2, but the closest I have come to an f1.2 is picking one up at a swap meet, so I have no idea of it's optical performance compared with an f1.4 (particularly reverse mounted on bellows for macro use). So my question to all you knowledgable people out there is: is a 50 mm f1.2 as sharp as an f1.4 when stopped down between f11 and f22, and is there anything you know about these lenses that I should know before I go out and try to buy one? Any and all help is greatly appreciated. Leon http://www.bluering.org.au http://www.bluering.org.au/leon - This message is from the Pentax-Discuss Mail List.
