their current 85mm f1.4 is brilliant I could see them leaving the optics the same and releasing this in the new body and build quite quicklyWhat is the problem with the Tammy build quality? Mine is impeccable!
the 50mm needs an optical redo but would be a big hit
I think they really need to get a 24-70 f2.8 OS out to compete with tamron (i'm hoping for this before anything else) The Tamrons build is a dealbreaker for me but the newst sigmas on the market are really well made.
I just bought the Tamron 24-70 f/2.8 VC ... although it is heavy and feels nice in the hand, you can see the workmanship is not upto Canon's L lenses, not even close to the cheaper ones like 24-105 L or 17-40 L ... you can check it out yourself, hold the 24-70 VC in your hands (looking down at it) with some light shining through from underneath the lens ... you will see the gap between the gold ring and the focus ring singlificantly bigger than the cheapest of Canon L lenses. I am not saying that the lens is bad optically or that it does not perform well, its a great lens optically for just $1049 and its VC is better than Canon 70-200 f/2.8 L IS II ... and I have been using only the tammy for the past 10 days ... having said that I would be really scared of dropping the Tammy, coz something about its feel makes me think that it will fall apart ... whereas my 24-105 L has seen many falls and survvived, including dust in its zoom ring, but it still works as good as the day I bought it years ago.
