Hey Ulf, perhaps this doesn´t apply to all Sigma lenses. My Sigma Mirror 600/8
was bought used for 1450 SKR (about 180 USD) almost 10 years ago and has been
used twice on dusty Kenya trips with a friend of mine. Apart from the focussing
which wasn´t all that smooth (from internal dust?) at first when I got it back,
it was OK. After some use however it felt just fine again. Several tourists
that he met on those trips commented that this combo, the OM-2SP and the Sigma
600 mirror lens gave a better view than most of the binocluars that they used
themselves! He actually managed to take several really sharp photos of some
rare antilops that hardly would have been possible with a shorter lens, and
this without a tripod. The short DOF makes focussing somewhat critical though.
