    Comments about Samyang 500mm f/8.0 Mirror Lens:

    I was looking for something small & inexpensive and easy to stuff into my camera bag, but not necessarily something my livelihood depended upon. This lens fit well into that idea.
    It is sharp enough, but lacks the crisp clarity / contrast I would like to see. Adding a polarizer seems to help somewhat, which is my general plan anyways.
    Do wish it was a dedicated mount as I am having issues with finding a good T-mount adapter.
    I would not consider this lens if your photography depends on images requiring this focal length.
