Originally posted by NitroDC I think the perfect compromise between SDM and screwdrive is the new DC motor in the 18-135. It's quiet (a little louder than SDM), fast, and looks to be super accurate. It also seems pretty reliable as you haven't heard about any motor issues in the time it's been out (which has been a while).
Pentax should put DC motors in all their new lenses.
I concur.
In fact, I suspect the DA* 16-85 will have this and might replace the DA*16-50.
Also suspect the DA 120-380 to have this and be WR. It is the natural complement to the 18-135mm.
These are all APS-C lenses IMO.
As for wide, they need a WR. Again, APS-C.
I don't think you'll see more primes that are fast like 1.4. That's such a tiny niche both for zooms and primes Pentax will cede that market to the used gear and third party brands. High-ISO has obviated much of the functional use of very shallow DOF lenses.
I find the pace of Pentax lens releases to be very slow compared to, say, Fuji. When rounding out the APS-C system it's definitely an issue for sales and interest.
