18-135mm autofocus only works in liveview

It is a really good lens, and worth the price of a new one. Speaking of AF, normally its AF performance is fast, silent, and sure. Above average among Pentax lenses.

good news is, I looked back through his listing that I had saved, and he does have a 30 day no question return policy. So I've contacted him to get it sent it back. Sucks that it didn't work out because I was really excited for this lens, but at least the seller is accepting returns.

If I'd buy a lens with an inbuilt motor, I would ONLY buy it new!
Also the DC-motor does fail much more rarely than the bloody SDM-Pentax-motor it can fail.
So does the socalled SDM-motor of the Tamron made 18-270! I know a person which had one and after a few years the motor zoomed very very slow.

Yeah. Once I get my refund, I'm just gonna pay the price for a new one instead of gamble with a used lens again.
