Tamron 85 f/1.8 VC & 90 f/2.8 Macro Images Leak

Re: Tamron 85 f/1.8 VC & 90 f/2.8 Macro Images Leak

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).

Compare the optical diagram of the new Tamron 85 announced today:
http://www.tamron-usa.com/F016special/index.html

with the optical diagram of the Zeiss 85 Batis:

and with the optical diagram of this Tamron 85/1.8 patent which is identical to Zeiss 85/1.8 Batis:
http://egami.blog.so-net.ne.jp/2015-05-27

So, it appears that the Batis is a Tamron design -- they have the patent -- but they are not using that design in the new Tamron 85 lens. This would explain why the Sony mount version of the Tamron 85 is A-mount, not E-mount. If it were the same as the Batis, it would be E-mount.

The Batis 85 sits much closer to the sensor, so it would make no sense to use the same optical design for DSLRs.

Thanks for pointing out my error(s).

this thing is designed pro wedding pros

If you are a 35 / 85 shooter, you can now have 2 modern, sharp at F1.8, weather sealed, IS lenses.

One of the major reasons that weddings pros drag along Canon's heavy white 70-200 lens is the IS - IS is going to be the number one reason this lens is sold (the weather sealing is huge also) - if you put it and their close focusing 35 or 45 IS, you wouldn't need another lenses.

85 is a niche market, the price of this lens will be whatever wedding pros will pay - my guess is close to $1k and then they will judge demand after trying this price point - especially with it 'reportedly' being tack sharp across the face

Well, it's prettier. But I spend little time looking at my lenses. If it had been 60mm or even better, 1:2, I might have ordered it.

Why is there no competition for Zeiss in MF-only lenses?

And when will Tamron offer a long prime?

Sorry, off-topic...

The Batis is 11 elements in 8 groups, while the Tamron is 13 elements in 9 groups, which does explain some of the weight difference.

Cosina manufacturers the Batis lenses.
