I would not simply jump to the conclusion that $900-1000 is ridiculous for this new Tamron 85/1.8 VC.
The patent shows the same optical design (http://egami.blog.so-net.ne.jp/2015-05-27) as used in the $1,200 Zeiss Batis 85/1.8. I think it is safe to assume the optics will perform quite well wide open.
...
What if Tamron did design and build the Zeiss Batis 85/1.8 and used the same basis for their 85/1.8 VC?
The only significant difference would be the casing and label.
Or in other words, Tamron are manufacturing the Zeiss Batis 85/1.8 under license from Zeiss? As a lens that is being targeted at a much wider audience than the higher priced Zeiss lenses, Zeiss would need to be getting that extra manufacturing capacity from somewhere else...
Yes, interesting suggestion, the Batis 85 has long been rumored to be a Tamron design. Of course the Zeiss version might have higher quality control / less sample variation issues. However, I'm a bit puzzled by the huge difference in weight between the two (DPR says 700 gram for the Tamron 85VC, and 475gram for the Batis 85; maybe DPR spec for the Tamron is wrong?).
Still, it better be good because not only is there a much cheaper and reliable Canon 1.8/85, Nikon also has a recent and excellent 1.8/85G lens that isn't much more expensive than the Canon one (plus the 85VC is in the price range of non-VC 1.4/85 lenses).
