Looks very interesting. I used to own the old 90 macro and was very fond of it...apart from its sluggish AF.
The 85/1.8 could have real potential as well.

Indeed interesting, to that they launch the TAP-in console (https://www.tamron.co.jp/en/news/release_2016/0222_3.html) with similar functionality as the Sigma USB Dock.
-
I get the notion Tamron is doing something right , 15-30, 45. etc
-
It seems you're able to adjust the sensitivity of the focus ring. I take that to imply that the new lenses are focus by wire and that the focus throw can be adhusted.
Note that Tamron now introduces electronic diaphragm also for Nikon F mount lenses, 90/2.8 and 85/1.8.

The VC on the 85 is quite interesting
I always struggle shooting the 85 at speeds under 1/250, usually reaching such speeds is not a problem, but for the odd shot where one prefers to keep the ISO at low levels I see it being useful

Hand held shooting a thin DOF 85 can be a challenge. That's one of the big drawbacks with the Zeiss MF 85'ers.

So i have noticed on the few zeiss lenses i have wide open the green confirmation dot is off and seeing through the viewfinder seems harder than in comparable situations with nikkors?

Nice to see IS making it's way further into the fast prime territory.

as a big time bug shooter, i am very interested in what the 90mm can do :o :o :o
-
I doubt it will be optically much better than the current models, which is already highly regarded. Unless there are significant improvements somehow, I'd see the best thing about this one is driving the prices of the previous VC model lower on ebay.

the current 105VR starts showing the effects of diffraction earlier than the 105D by almost a stop in my tests. i also noticed this the first time i shot with the 105VR when i bought it new some years ago. the actual t-stop is also different, by around 0.7 stops (wide open). if the Tamron shows better handling of diffraction then i am probably sold :o :o :o

I did this test last year, around summer i think. but i noticed this first in 2012 the first time i got the 105VR.

You are far more well versed on this lens series than I am! I hope the new one corrects the issues you've found with it!

i shoot bugs every opportunity i got :o :o :o
the 85mm f/1.8VC looks exciting as well. I tried their 35mm and 45mm and they were both AWESOME lenses for their price. the build quality is also great

Why is the green dot off?
these zeiss lenses i mention have no cpu contacts, so my only guess now is that register distances are not accurate,( which is more sensitive at larger apertures).

I have many old lenses for Nikon without cpu, but the dot works, D800.

Right, i dont have such issues with the many old nikkors i use, but with the zf 35/2 and 85/1.4, maybe with 100/2 i am not sure about the last , well its a macrolens anyway so i use lv here, thank you Karl.
-
The green dot may behave differently with different lenses. Due to some unknown-to-me optical principles, my ZF 85/1.4 and ZF.2 25/2(both now gone) seemed more difficult to eye focus than other ZF lenses.

But it also works with old manuel Vivitars and Sigmas, why does it not work with Zeiss?

to narrow it down my copy zf35mm f/2 is the real bitch, i simply can not focus at f2

On all Nikon bodies? My experience with D700 and Zf35/2 is a bit the same, on the Df and 800E it all goes smoother. I hardly use the green dot by the way, focus-screen only. Only in dark situations it is inevitable.
-
With my D3, the ZF 35/2 was relatively easy to eye focus. It is only slightly more difficult with the D800/E, but only because my D800 finder is optically inferior to my D3 finder.
-
first my eyesight is not optimal, second distance to focuspoint is important, third which focus crosspoint is selected, when ambient light distorts contrasts,
on the d800 i have 1,2X magnifying eyepiece with helps and liveview is no problem
-
DPR is reporting that the 85mm in F mount has an electronic aperature, they don't mention anything about it on the 90mm

check my samples of the tamrons!!! :o :o :o
damn this is an awesome lens!

For me a drawback to most non-Nikkor lenses is they frequently focus the reverse direction to Nikkor lenses. This messes with my reflexes when I use manual focus.
Years ago I bought a 400/6.3 Tele-Astronar preset lens. Later when I bought an 80-200/4.5 Nikkor I found I focused the correct direction at the close end of the zoom but backwards at the long end. The fingers had learned that long lenses focus the reverse direction to other lenses. I parted ways with the 400/6.3.
A switch to a different camera system isn't much of a problem. It's when lenses for one system focus reverse to each other.

Indeed. The 45/1.8 is not only good, it is also a "lens with a personality", and its "signature" is very different from Zeiss. This is all good news.
