They are also really, really cheap. I think I paid $35 for the 135mm and $45 for the 35mm. The 85mm 1.8 is a rare one that is fast for a 60’s era lens and i use it to match with other similar era lens sets that never got a fast 85mm. Got that one for $150 so it was a score. There’s even a super rare 135mm f/1.5 “Vivitar Professional” In the set but pretty soft and overpriced, ($2,500) these days.
The 135mm f/3.5 is super tiny. (pic 2)
