Originally posted by smrk OK those who have both the DA 35mm f2.4 and the DA 50mm f1.8 how much of a difference in the focus ring dampening is there?
I just picked up a used DA 50mm f1.8 and the first thing I noticed is how much more dampened the focus ring is between it and my DA 35.
My DA 35 has minimal dampening which I was figuring was to improve autofocus speeds
The 50mm feels a lot more like an old school manual lens (not really a bad thing, as its much better for manual focusing) but it is noticeably slower (and louder) autofocusing than the 35mm
As a used Item I am trying to figure out if it needs to be returned so I figured I would query the forum here to get some feed back.
Perfectly normal, the DA 50mm is nicely damped while the DA 35 2.4 offers basically no resistance in the focus ring.
Pentax engineers usually think about details, so I would not be surprised that they would have thought that the DA 50, being a manual prime with a shallower DOF, would be a lens where the photographer would want to use with manual focus to get the eyes in focus, if needed. With the DS 35 2.4, on the other hand, the DOF is larger, so people would usually not use manual focus with it for fine tuning. Of course with both you'll have to switch the AF switch to manual focus, to be able to use the focus ring...
