I think it's really silly that when one has tried ONE or even two samples of ANY particular lens and finds it to be particularly good, they can somehow delude themselves that ALL of the samples are that good. They are the same ones that got a really bad 50/2 M or whatever and so ALL of those must be junk. It's malarkey.
I'll take a GREAT sample of a lowly 85/2 over a mediocre sample of a precious 77/1.8 ltd. any day. I think the only way to get a great collection of Pentax primes is to buy 'em, test 'em in the real world, and dump 'em if they don't do it for you. Not all of them are gems, and conventional wisdom isn't. Chris L. School Publications Guy
