Originally posted by clickclick Thanks for the replies - this is making more sense. I have 35, 50, and 55mm Takumar lenses on hand and was able to get almost all of a slide in the frame with the 55 - close enough I could live with it for most shots. It was just a tiny loss on one edge. I was thinking with the 100 bellows lens I'd get the whole thing in. Am I off on that? Regardless, it sounds like I should look for a bellows 100 versus a full size lens for work any work with the bellows and that focal length.
No. With the 100 set at about 1.5:1, which is what you need to copy all of a 35mm slide to an ASP-C sensor, the distance from lens to slide will be far too great for the slide copy bellows attachment. I tried, and the devise cannot be extended any where near far enough. In fact, I was unable to obtain focus on a slide mounted in the device at any reproduction ratio using the 100mm bellows lens.
