since i dont want to spend crazy amounts on a adapter with a chip in it

thanks guys

for what body?

for a mirrorless camera i would jupiter 3 or 8 - cheap decent 50mm - the f2 verson as cheap as £30 in some places

for an slr carl zeiss jena 135mm f3.5 is awesome, as well as hundreds of m42 lens (look into old pentax lens)

i have a nex 6

ill look into the jupiter since it looks pretty good for the price.

i have the 3 and 8 both are superb!
if you get some more money buy a zeiss 35mm biogon either the f2 or the 2.8 they are quiet simply perfect!
