I'd say that ~100 usd is max that vast majority of vintage glass is worth. For more you can actually buy modern primes and modern primes, especially with mirrorless design can be fucking excellent. Pic related shoot with samyang 50 f1.2 The lens have character on its own and I'm glad I was shooting with it and not with something like minolta 50 f1.7.
Vintage is fun for messing with lens character, but buy cheap like helios, zenit/zenitar, jupiter, maybe some takumars. Don't fall for memes of canon/hexar/minolta 50 f1.2 that cost just as much as modern af lenses.
