Tamron 17-50 Focus

Please help! I'm in a panic...

I am a new K-5 user and have been using my DA 35mm lens only until today, when I decided to mount my new Tamron SP AF 17-50 and it appears something is wrong. The camera is set to auto focus, but it appears to not be focusing as everything appears blurry through the viewfinder. Is there a setting somewhere I needed to change for this non-Pentax lens? I really apologize for asking what is such a simple question for the majority of readers, but I do need help. Thanks. Cathy

No.... it should just work. It sounds like the pins could not be making contact. try removing the lens and try again snapping it into place.
Not too hard and vigourous of course lol. the only differance using the tamron is you will lose the auto lens correction in JPG mode.
If it doesnt work, exchange it. It can hardly be the camera if the other lens works. Its a strange one. The only thing I can think is stiffness from being new possably.
