#1

Tamron 28-75mm f/2.8 XR Di Pentax K

Tamron 28-75mm f/2.8 XR Di Pentax K

"It is capable of stunning color and sharply isolated portraits with a very neat bokeh. I have 2 K100d bodies, a K20, and a K-x, and unlike my other lenses, it does equally good on all four of them! The bright f/2.8 ratio makes this a winner indoors and also outside for depth of field control." bhphotovideo.com

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

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
