>>3204877I've amassed a lot of old glass, 90% of the time you get what you pay for, 10% of the time it's massively overpriced.
Here's my tier list for common vintage brands though
God - nikkor, canon fd, rokkor
Mid - asahi pentax, some russian stuff, pentacon, old canon ef, fuji, carl zeiss jena
Trash - soligor, centon, chinon, sears, etc, all the rebadged China shit.
Wide angles generally are trash compared to modern counterparts as they are hard to design, especially once you go past 28mm. And sony allows for much better wide angle designs than old slr lenses due to the short flange distance, look at samyang if you want cheap and decent performance.
>>3204880It's a great lens, out resolves the 50 1.4 that costs about twice as much!
