| 800mm mirror lens There are 3 new 800mm mirror lens on the market by Vivitar,,Bower and
Samyang. I understand that they are all the same with just different
branding, has anybody tried them out, or read any reviews
whilst not expecting them to compete with L glass, they may be better than a spotting scope for (distant) wildlife and I cannot justify a 800 sigma or canon.
I was thinking about the Sigmonster but the price has jumped from
about 7000 usd to 12000 usd due to currency movments in the last
couple of months so that is out of the question, I could put a 2 x
convertor onto my canon 100-400 but I could also put the convertor
on the 800mm mirror and get 1600mm and with the 5dmk2 usable
ISO range not have to worry too much about shake..
any feedback appreciated
