The focussing smoothness and freedom from backlash ( hope you know what that means ) of the Pentax lenses got worse as they went from SMCT to K to M to A ( especially from M to A ), and then of course Got much worse on the AF lenses by design but that Was OK as a tradeoff if you really needed or wanted AF. But if you don't need or want AF all the lenses After SMCT just got worse with regards to the focussing Action. The SMCTs are still top of he heap. I am NOT Reffering to optical properties here, I am referring To the manual focus mechanism smoothness ( mechanical refinement ). jco

I've used ST, SMCT, K, M, A, and FA lenses, and while the focus feel may be different, they all manually focus quite well and with equal accuracy. Some may even say the later lenses, with greater contrast than older lenses, focus better. Shel > [Original Message] > From: J. C.
