>>2904628I use one on my film camera (because I'm an absolute madman). Haven't developed the film from it yet, but I had a lot of fun just using it for taking candid portraits of people. I basically go somewhere with a lot of people, set up my tripod, and let the people come to me.
I've always wanted a mirror lens, so I just had to get one, even if just for messing around.
I was going to get the Nikon 500mm mirror lens, but after reading this article, I decided to get the Tamron 500mm instead. Zeiss might be the best, but just too expensive, at least Tamron is the smallest and lightest.
