Pentax a 50mm 1.4 fast focus?

Hi

I dont know if it is a problem or not but my A 50 1.4 has very fast focus turning. It is not like my M lenses - smooth and slow.

Is my lens faulty or normal?

thanks

I can't check my copy at the moment as it's in for a CLA, but IIRC the action is not as damped as it is on my M. But I wouldn't call it "very fast", either; that doesn't sound normal to me.

Same here. I've owned M, A, F and FA 50 lenses. The A and M were close regarding the focus action, the F and FA much more lifeless and "fast" as you call it.

my copy of A50/1,4 have fast turning, but with rezistance, it gives good focus feel (similar as my a28/2,8)... if it is turning for you as fast as for example tamukar-a 28-80 (juck), it is wrong.

i hope tahat helps

I think my copy is somewhat not OK. Maybe needs relubing.
