In this instance, I would say you are right. Slide projectors tend to have really bad lenses, though I am sure there are exceptions. Also, there is no guarantee that the slide is perfectly parallel to the screen, or that the curvature of the lens field is identical to the curvature of the slide (there will be some, unless it is glass mounted). As well, to get maximum light transmission, projector lenses tend to be pretty fast optics, which leads to a whole nother set of problems. Making a decision about camera lens quality by viewing a slide show isn't thinking things through very well. William Robb
