As far I haven't got a bad 135mm lens.
Among the best I have been used are: M135/3.5, K135/3.5, K135/2.5, Pentacon 135/2.8, SmcTak 135/3.5, SmcTak 135/2.5, and all my 3 vivitars 135/2.8 in different mounts...

So which one I use?
M135/3.5 for light weight with build in hood.
K135/2.5 for low light.
Pentacon 135/2.8 is razor sharp wide open.
and Takumars and m42 with canon body.

even single coated Olympus OM 135/3.5 is good.

..both not to be overlooked, decently sharp, especially with $60 budget, with luck you can even get both of them
