I think Russ is on about the new 150-500.Have just read about someone who bought one and also has the 170-500 and did a comparison.The 150-500 was so far behind the 170-500 that he sent it back to Sigma thinking it was faulty.When he got it back it was just as bad.He is not a happy chappy.

Newbie here.Could somebody tell me what back focussing is please.I have a K10D and have taken what I thought were great photo`s with a Bigma at good shutter speeds whilst resting on a beanbag but when I get them on the computer they seem slightly out of focus.
