Compatible with Olympus Evolt 500. Frame edges similar in appearance to other cheaper similar products. A nice surprise that I didn't understand from the product description is that it actually comes with a macro adapter like other products. It's certainly easy to use, but I'm not sure how useful this product will be for me. At the moment I mainly photograph my children and rarely do panoramas with the evolt 500. I'm glad I didn't spend more money as both would probably only be of limited use…
