Query: Works well for the money

For the money, you can't beat the Opteka slide copier. It worked as advertised. I copied several slides made back in the 1960's from a 110 film camera. While the slide frames fit in the copier, the opening wasn't large enough to get the entire image top to bottom. If the detail I wanted was on the very top of the slide, I inserted it into the copier upside down and vise versa. However, slides produced from 35mm film fit perfectly. I used a Nikon 35-105 macro lens in macro mode on a Nikon D3. Had to manually focus, but it worked fine. I only used that lens because it was the only lens with 52mm filter size. Bottom line, for the money this did the job. It was much quicker than a slide scanner.
