Originally posted by PentaxPoke I disagree that the lens is not sharp. Look at this, it is wide open! The fact that a 30-something year old manual, 3rd party lens can be this sharp makes me think that we are being taken when buying new lenses!
Yes! There are lots of things wrong with my Sears 135/2.8 but lack of sharpness is not one of them. Even wide open the centre is sharp and the edges come into shape pretty quickly once you stop it down a bit. At about f8 it is clearly sharper than my DA*300. OK not a fair comparison but it does make you wonder about new lenses and just how some old lenses were so good.
Were they able to use materials back then that are now banned?
Regarding the built in hood;
I love it, but it only extends 15mm.
Needs to go at least 40mm.
