trying out some new old lenses

got three "new" old lenses from my grandpa since he was cleaning out his basement and doesn't need them anymore :) he's really spoiling me with all his old photography stuff! it's two 50mm lenses (Zeiss Jena Tessar 50mm f2.8 and another one I don't rememebr) and a zoom lens (Osawa 80-200mm f4.5).
naturally I had to take them with me to the zoo and try them out and they are quite good as soon as you're used to the manual focus

50mm...

...compared to 80-200

definitely liking the zoom lens for the zoo
