Summary: I have tried reversing rings on manual bodies in the past and while they are cost effective, they are inconvenient to use since you have to calculate the exposure manually. This extension tube is simple to use but brings the photo so much closer, which is great not only for insects, praying mantids, etc., but for getting closeups of childrens' faces. I should have spent the money years ago.
Pros: Durable, Easy to Use, Improves Function, Lightweight, Small
Summary: I purchased this extension tube to take the place of a +10 macro filter. It really did the trick and has made my macro shots something to be proud of. The threads are a little snug, so be careful when attaching it to your lens.
Pros: Durable, Easy To Use, Improves Product Function, Lightweight
