Hive everyone i hope that you are all having a great day, then recently i made a lot researchers about photography in general and cameras, lenses in specific by a coincidence i found a topic talking about a type of lenses called vintage lenses there old most of it if we didn't say all of it from the 20th century anc have a fully manual control there is no auto focus or these stuff. I went to the thrift stores in my city and i found this i buy it for 10$.
Old porst camera with four lenses M42 screw mount, Porst 55mm f1.4, Jupiter 37A 135mm f3.5, Aremac 135mm f2.8 and Carenar 34mm f2.8 this one wasn't sharp at all the others were surprisingly sharp.
Jupiter 37A 135mm f3.5
A Soviet prime telephoto lens sharp with a swirly bokeh most of the photographers whom used it called it the bokeh monster actually most of the lenses i saw on the same focal length deserve the same title as well price range between 50$ and 100$ actually, the minimum focusing distance 1.2 meter.
Porst color reflex MC auto 55mm f1.4
This one is my favourite a very sharp lens i was looking for a good fifty nifty lens i didn't handle a modern one but this one equivalent +1000$ modern lens with half of meter minimum focusing distance gives a full control to capture a sharp images the contrast also is great in this lens.
I won't talk about the other lenses they were very bad lenses actually which sometimes in thrift stores you can find good stuff and also bad stuff always look for a specific things and google it. I will make a video and more about this topic of vintage lenses till that moment stay safe.
