Carl Zeiss Sonnar T* 2.8/135

My first Contax lens was Carl Zeiss Sonnar T* 2.8/135. I had few 135mm (SMC Pentax 1:2.5 135mm, Meyer-Optik Gorlitz Orestor 2.8/135 , Leitz Elmarit-R 1:2.8/135) and after comparing them all together I decided to stay with Contax. It is well build lens w build-in hood. Very sharp, with beautiful bokeh and color rendition.
This lens was converted to K mount using Leitax solution.

Carl Zeiss Vario-Sonnar T* 3,3-4,0/28-85

And here is my second Contax lens. Looking for some time for best zoom in 2x-70/80 range I decided to buy Carl Zeiss Vario-Sonnar T* 3,3-4,0/28-85.

I made some comparision tests with best prime lenses. It looks that CZ 28-85 is very sharp wide open and sharp it means in the center and on borders and not so far from best primes. At 28, 35 and 50mm my Sigma 17-50/2.8 DC OS HSM is less sharp without any discussion. From 28mm till 35mm abberations (green fringle) is worse than in my prime lenses.
Lens is quite big and heavy. There are 16 elements inside. Lens has big front - 82mm filter size. Zoom is pump type and i found it to be quite usefull.

Modified this MM version Sonnar to PK-mount with Leitax mount adapter. First pictures with Pentax K-30 taken.

I have a Tokina 500mm f/8 mirror in a Contax mount, which I converted to K-mount by drilling screw holes in an extension tube mount, and replacing the mount on the lens with it. (It was a perfect fit, extremely snug).

It's really a rather terrible lens. Low contrast, hard to focus, and not at all sharp. But strangely, it's pretty decent on ring-shaped highlights. Oh they're there, but they're not as pronounced as some other mirror lenses. But quite honestly, a $50 Spiratone Sharpshooter 400mm f6.3 blows it out of the water as far as sharpness is concerned. The mirror does kind of win with handling though...

Last night, I asked David from Leitax, if it would be possible to make a PK mount for the Contax 100-300.
He replied it would be possible and is going to look into it. For me that lens is the holy grail of zooms. Just imagine, the K-1 with that lens, lighter (925 grams) and smaller in that zoom range then other modern offerings and with it's stunning IQ.

I already have the 35-70/3.4 and it's resolving power keeps amazing me. Would be great to have the 100-300 with it!

Oh Dear! I see a whole new LBA field of activity opening up for me, the definition of these lenses is very very good, well done all but particularly Piotr for showing how good the K20D still is.
