Title: Poor Image Quality
Review: These do work to effectively give you a much smaller minimum focusing distance, thereby increasing the size of your image. But it comes at a very high cost in image quality. The Image degradation increases substantial between the +1 to the +4 Diopters, with the +1 being fairly usable, and the +4 being total junk. On the plus side, the case is nice. I am considering dumping the diopters at home, and putting my other filters in the case.
