Sigma 300-800mm ?

Does anyone know who sells the Sigma 300-800mm in a Pentax mount? I see them for the other cameras but not for my K10D (soon to be K20D!).

I can't believe I am actually thinking for buying one but just maybe. If I do, I guess I'll have to buy a Gimbal Mount too. Yikes, what am I thinking?

Thanks,
Phil

I finally just checked on the Sigma site and it doesn't look like they make the thing in a Pentax mount. I guess that explains why I couldn't fine one!

If anyone has a recommendation on 600mm or up lens that is made and available for under 10k for a K20D, please let me know.

Thanks!
Phil

There is the Pentax 600mm F4 which I could only find at one place on ebay right now.

Other long lenses available are from Sigma & Tamron.

I just got the Sigma 300mm f2.8 with a 1.4X and 2X teleconverter. With the TCs attached, it becomes a 420mm f4 and a 600mm f5.6 equivalent and it is very sharp!

EDIT: Sigma did make the 800mm f5.6 for a while, but it isn't as good as the 300-800mm f5.6 according to some reviews. Also, it's kind of hard to find the 800mm nowadays.

The Pentax 600 f/4 is under 10K, I think there was one for sale in the for sale forum and is an ebay store that sells it new for ~$8200
