Hi Tom, the Tessar is a very old optical design. The 2.8/50 was the medium quality of 3 different options for standard lenses offered on Praktica SLRs in the 60s, so this tells you where it is quality-wise. The other lenses were the Pancolar and the Meyer Domiplan.
It's soft wide open but becomes much sharper stopped down, and has a nice, smooth bokeh. Focus changes as you stop down, so you need to focus at the taking aperture, which is a pain.
One thing's certain - your Pentax 1.7/50 is a better lens, so if you don't need the Tessar I would say save your money. |
