The lens in this test has a minimum focus distance of 12'' inches. When the filter was installed it moved the lens in by 2" inches. That's 10" inches to object. They just bring you in closer. That's why they call them close up filters. Not magnifiers. The true term diopter. If I had a +10 diopter on may be 5" closer. I believe they just help you to focus closer. Yes the 8 is bigger, is it magnified or is it the lens just being closer that makes it look like being magnified
