Title: Difficult to use
Review: The concept and construction of this accessory are great, but the instructions only state how to attach it to the camera: you have to zoom way too much to fill the screen with the image of the slide you're trying to copy, a tripod is needed to hold it rock-steady. the camera won't auto focus, and you have to manually focus and it takes quite a few passes to get it right. I rate this item in the "ballbuster" category, but it will work if you have a calm mind.
