I think you're right. The Sigma 8-16mm is the best DX UWA out there now, and it only goes for $700. Imagine how good a lens with $1700 worth of optics could do. With the 8-16mm, Sigma has proven they can make exceptional lenses, and the 70-200 OS is in the same batch of new lens types along with the 50-500 OS, another exceptional lens.
I think people are just assuming that because it's Sigma and not Nikon, it's not going to be as good as Nikon glass. Sigma has seen how good the Nikon 70-200 VRII is, and still chose to go with this price. They're not stupid, so I suspect they already know how well their lens competes. I would not be a bit surprised if it was as good at the 70-200 VRII optically (maybe less good at 200mm but better elsewhere in the focal range), and figure that once people starts noticing this (if it's true), they'll start buying.
So I ask people, if the Sigma 70-200 OS were as good as the Nikon VRII, what price would you set for it?
i totally agree with this. actually i ve thought about this like you. they must be a fool if they dont come up with the quality to set the price of this lens this high.
and yeah, i remember people raving about 8-16 and its got the FLD element. so maybe this new 70-200 OS will deliver. but I am still terrified with sigma QC, sample variation.
if it was as good as VR 2, i am still thinking that 1700 is asking too much.
the VR 1 was 1700 bucks and sigma 70-200 was like 700 around that time (so its like 41% of price of nikon)
so now VR 2 cost 2200 bucks, so i expect sigma to be around 900 - 1000 bucks. that would be right. 1100 tops. but 1700 is asking too much no matter from what angle i am lookin at it.
but hey, i am also excited to see what sigma can bring to the table with their new 70-200 and 85.
and if they can do well, then tamron and tokina will start to follow their steps and what this means that we as customer will have more options in the future : )
