This is a light weight, small and compact tele-photo lens. Probably will not draw too much interest by today standard where a 135 f2.8 is already quite a light package. However the tele-tessar is still a very impressive light weight alternative. I have a chance to use it again with the full frame digital Alpha 7R and found the photos very satisfactory. Mine is a made in Singapore copy with very nice purplish-reddish HFT coating.
Certainly a lens that I will bring along on a day that I feel lazy : )
This lens has been kept in the dry cabinet for a long while. I take up to use again because I found out there are CA even with the Contax 100/2.8 Makro-Planar under certain situation and also the Contax 300/4 Tele-Tessar. But surprisingly the CA of this 135/4 HFT Tele-Tessar is very low. Of course due to the lens technology and the age the resolution is not as good as the modern lenses, but frankly that can only be easily determined on computer and very tight cropping. When print the photos in 8R size the photo is very sharp and good.
