One of the things I discovered in doing some tests before using it to photograph eyes before surgery was that it gave a circular highlight/reflection that made it near impossible to see anything on the cornea itself..... I'm not sure how it would work on photographing the thickness of lenses..... In the end I discovered that I could mask out all of the ringlight except for about 1/2 to 3/4 of an inch on either side. This gave two smaller highlights and great results. I prefer doing exposure by distance and I used a Minolta flashmeter to help make a chart of correct exposures..... remember to include the extension factor in your exposure calculations though....... and do some tests! I've never seen a real R-8 in action so that may work as well. There is also a Vivitar ringlight 5000 that can be had for around $80 if I remember right. Duane Birkey HCJB World Radio Quito Ecuador
