Tamron 17-50mm f/2.8 XR Di-II LD [IF] Pentax K

"The quality of the lens feels great and you come away feeling like you're getting a lot for your money. The ability to lock it into 17mm is handy for transportation and twisting it onto your body. The AF is audible but not loud enough to make it seem cheap." bhphotovideo.com
