    I was wondering if anyone has used one of these things before. Something this cheap may be worth looking into for fun. Of coarse there is draw backs in it with the fixed aperture but I'm sure they may be plus' to something like this but I don't know. What do you think?

    Thanks for the Amazon review link. I always forget to look there since I'm in Canada and amazon.ca doesn't sell everything like amazon.com does.

    I wasn't really expecting awsomeness out of something like this but decent enough for night photo's of the moon or northern lights and stuff.

    First thing to note is the f/8 max aperture
    Second thing to note is that the aperture is fixed at f/8
    Third thing to note is that the lens is a mirror type lens which tends to produce distracting donut shaped highlights in out of focus areas.

    On the plus side... mirror lenses are very compact compared to their equivalent refracting counterparts.

    I saw few shot sample of this lens at flickr website, they are okay for this price, especially for UFO shooting if I they cross me. The f8 make it even better, I don't have to think of it.

    Can anyone tell me if it is can be mounted on d40? I know it won't focus and want meter either.
