Sorry, just caught your post now . . .

 

Both the Minolta 85 2. 0 and the Zeiss C/Y are good, sharp lenses.  While this domain can be subjective, to me the Zeiss' colors are brighter and more saturated and images from the the lens tend to have the classic Zeiss "pop" to them, and while the Minolta has good contrast to my eyes the lens renders a little harsher than the Zeiss.  But, again, differences are not huge and I would be happy shooting either lens.  The Zeiss is definitely a little bit lighter and a little bit smaller.

BTW, the Contax 85/2.8 and the Contax G 90/2.8 are basically the same lens, just with a different mount, even if you would be forgiven to think differently given the slight difference in focal length.

 

Contax just repurposed the same optical scheme used for the G series of cameras in a lens made for their SLR, altering a bit the spacing through the elements.

 

MTF charts, directly from Zeiss

 

Sonnar T* 2,8/85

 

Sonnar T* 2.8/90

 

The 85/2.8 is just a tiny bit better at the extreme corners, like you would expect from a lens made for an SLR so with a bigger flange focal distance (easier to correct flaws).

 

And now with the Techart adapters you are able to use both in AF if you have an A7 II or newer camera!

Are there any user reviews of the Techart yet? Or is it still too early.
Ps +1 on the CY 85 2.8, small and packs a punch well above its weight!

As far as I can tell, still none. I'm really looking forward to see if it performs well enough on the original A7r, despite the manufacturer claims that it should work only on the newer, PDAF enabled, models...

I just received mine for Contax G and at first view it doesn't work well with the A7R. It hunts even under good light, and it doesn't even nail the focus. There is an adjustment for that, which I have not yet tried. Manual focusing works very well, though.

 

That 90mm is a very impressive lens, I'll soon test it against the 85mm C/Y.

 

Or are you talking about the universal model by Techart for MF lenses?

Sharpest? Just go with either FD 85/1.2 L or SSC Aspherical, even Contax 85/1.2 can't beat them. Jupiter 9 or Helios-40 are good choices too but you have to stop down a bit to be really sharp.

i have some 80 - 90 legacy lenses

 

i would say the contax G90 2.8 ls very sharp but has to much contrast, so it is not so good for portrait but very good for landscape etc.

for portrait very good is the leica summicron 90mm  

 

also very good is the Sony 85mm and has AF (with sony adapter) but contrast and sharpness from the contax is much better but the sony is better

for portrait but not as good as the summicron but o.k.

 

awesome is the mamiya 80mm 2.8 and i think there is also a 80mm 1.9 (but more weight), it is a mediumformat lens but very light and manual focusing is like a dream...so smooth and precise .....and very sharp!  and cheap but you need two adapters  mamaya 645 to cannon or nikon and adapter to sony e-mount

 

the contax G90 has not such nice focussing so if you want the lens for landscape go for the C/Y 85mm or the mamiya because of smooth manualfocus, the mamaiya is a better allrounder..... portrait and landscape is great

 

if you want to spare money for the batis you could try the minolta MD 135mm 3.5, it is very small cheap and comes very close to the Contax G90

There's an adapter for Mamiya to E Mount. I'm buying some Mamiya glass to try. Thanks for the post as I was going to ask if anyone had tried a Mamiya lens?

JimmyD - thanks for your answer.

Even lighter and smaller ... wow. When I can catch a "green" version of the lens for a reasonable price I will purchase one. This can take some time ;-)

Would be nice for super light 35(Zony)/50/85 Kit.

The 90mm f2.8 Contax G is amazing and much better in the corners at f2.8 compared to the Contax 85mm C/Y. 

It even seems to perform better at f2.8 in the corners.

It wins a little by going to f4 but not much, 100% sharpness all over

Of course it could be a sample problem or so but I don’t think so. Joined a crop at 200% form one of the corners and at f2.8, yes all open.

The CA is removed if you selecting "remove chromatic aberration" in LR even without moving the sliders.

It’s just the best lens I own. Use it for landscaping when I need corner sharpness all over the image at f2.8 or f4.

On the other hand I think every lens mentioned above will be ok if you close the aperture to f8 or need it for portrait photography.

Hope it helps...

Thanks for the info! Even if they're disappointing...

Yes, I was talking about the universal model, but I doubt there will be much difference in performance.

so ........if the c/y sonnar has problems in the corner...thanks to Edward De Bruyn!

 

i would highly recommend the Mamiya Sekor C 80mm 2.8, i payed $90 + adapter

 

as it is a high quality mediumformat lens, it has open no vignetting, the same high sharpness in the corner as in the center ( better corner sharpness than the contax G90 ) and a very good focus experience

 

the contax G90mm 2.8 + adapter has 320g the mamiya 80mm 2.8 + adapter has 380g and is a little bit longer maybe 10mm

 

the only lens that is shaper i own is the Sigma 105mm 1:2.8 DG macro HSM OS..... this lens  is very close to the FE90 macro

Gilgenberg: "so ........if the c/y sonnar has problems in the corner...thanks to Edward De Bruyn!"

 

The problem 85mm Contax C/Y is not really a problem. It’s just not as sharp as the Contax G 90mm wide open, f2.8.

The fact is that my Contax G 90mm sample is extremely sharp. The samples were not sharpen and the crop sample is viewed at 200%.

However would like to see a test between the Contax G and the Mamiya regarding corner sharpness.

Would allow me to use it on the Mirex TS adapter. The reason why I invested in the Cantax C/Y lenses…
