I have a large amount of slides and negatives I want to digitize. I'm thinking about using a slide copier to do this, but own Nikon d5100- a crop sensor. After de-magnifying the image, how will this affect the original image's appearance (from the slide) in digital form?
This will drop my resolution, but will it do anything else too, like cause lens distortion? What type of lens would I want to use?
