Which one will work the best with my k100d?
Is the extra few hundred quid extra for the 50-500 worth it?

Photos with Sigma 170-500mm lens
Craig, I can't comment on the 50-500 (never used one), but I do own the Sigma 170-500 and use it on my DS. I've not had the opportunity to use it much, but just the other day I saw this "lizard" on my roof - something appeared to be wrong with it's tail and hind leg. Grabbed the zoom and took several shots, but wanted more reach to try to figure out what was wrong so added a *cheap* 2x teleconverter - the second shot was taken at 500mm with the 2x (1000mm total) - in manual mode. Other than the very small DOF, I can't fault the lens at all!!
Edit - additional info - I cropped both images so they would be the same apparant size to better compare the image quality.

I have been wondering about the same thing.I know the 50-500 has an HSM motor but is not available in Pentax mount with HSM.So is the optical quality that much better to warrant the £200 extra than the 170-500?.I have a K10D.

Im new tom this forum and i have a pentax k10d and use the sigma 170-500 ok it can struggle a tad in low light but most of the time it gives very good results and its £200 cheaper than the bigma, and dont forget the bigma is a heavy lens wheras the 170-500 is cosiderably lighter so hand held shots are more of an option
