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.
