Originally posted by David&karen On the 16-50 Pentax: The lens would fit my needs, but the SDM failures really scare me. I spend 5-10,000$ a year in travelling and if it dies on a trip it kills it. I could take the 18-55 WR as a back-up, and so I am thinking about the 16-50 lens again. This is what this forum is about: ideas!

David,
I would not worry excessively about SDM failure. In the unlikely that it does happen in the middle of a trip, the lens can still be used in manual focus mode. So, as long as you are comfortable with MF, the lens will remain very usable. And with the "Catch in Focus" feature on the K-5, the camera will give you focus confirmation with a little green light in the viewfinder.
