I used this for a butterfly shoot at a local zoo with a Nikon D50. I tried it on several lenses and pictures came out sharp and clear w/o light loss, and autofocus worked perfectly with filter on. I have not done an enlargement over 5x7 but I believe the image would hold up to greater sizes. This is a great inexpensive alternative to a macro lens if you do not take a lot of close ups in your photography.
