Pentax k-x is a pretty popular model in this holiday season (2009). This small DSLR camera are awesome because it has so much features in small package and relatively affordable price. The most important is the image quality and AF is so good in low light condition. Pentax k-x is successor to older Pentax k-m which shares the same form factor with different feature and image sensor.

For those who seek a fast and standard zoom, consider Tamron 17-50mm f/2.8 or Sigma 18-50mm f/2.8

The Tamron 18-250mm F/3.5-6.3 lens does not fit the Pentax K-x. I’d purchased the lens based on the recommendation on this page only to discover that the lens don’t fit. Now I have to return the lens and pay a 15% restocking fee plus shipping. Please revise the content. I want to thank you for taking the time to provide the content, but please make sure that future content is accurate before it get posted.

Sorry for your trouble. The previous link led to Nikon mount version. Now it is fixed.

i have the tamron 18-250mm 1:3.5-6.3 on my pentax kx and it fits and works perfect – it is model A18P and the box is labelled ‘for pentax’ — i think you may have ordered the lens without specifying ‘for pentax’? (it is a brilliant lens, especially for travelling).
