You are correct about the carrier holding the neg above the glass. Depending on the size of the negative, you can get some sag in the middle. I am scanning 67 negs and find that strips do better than single negs because the strip helps hold the neg more evenly. I would guess that 4X5 would have more problems with sag unless the emulsion was quite thick.
Overall, it is a nice scanner - especially for the price.
