Sigma 400mm 1:5.6 AF

If anyone has one of these they would like to part with i would be interested. Thanks
note: it must have AF

They do turn up on eBay.co.uk quite frequently, but as with a lot of the Pentax-fit A- and post-A- lenses, prices have been going up.

There were three over the summer, the first two of which I missed, and the third one I managed to win, but for more than I'd hoped.

If you can find an FA* 400 I'd trade...

I don't think i will bidding on an FA* But there are a couple of A 400s listed at the moment but i really want autofocus. The old eyes aren't what they used to be.
Do you have the sigma 400 AF : and the Pentax 400A :
Is the sigma 400 still in production :

Yes. I really like them both. The Sigma for its lightness and quick AF, and the Pentax for its better optics. I say better, but that's not to say the Sigma is bad, although it has a lot more CA than the Pentax wide open. Stopped down a bit it's hard to tell them apart.

No.

I just had a look at http://www.sigma-imaging-uk.com/, and it seems that they don't make any 400mm telephoto any more. They do a 500mm, but not in a Pentax mount.

I recently got a Sigma 400mm AF too. I find it light and very usable. The AF makes a racket, but is quick and locks quickly too. I've had a lot of PF within mine (I'm doing a lot of shots over water at the moment), but stopping down a little and adding a UV Haze filter seems to have helped.

Oh, Clarkly, I don't want to part with it I've also seen a few up on Ebay recently.

Apparently, they do do the 500mm f4.5 in Pentax mount, but you have to either hunt it down or order it specially. If you look at the Sigma USA site it does mention it for the Pentax mount and I've seen sites on the web where the photographer is using a Pentax mount one. Deep pockets required.

Thanks guys i will trawl through e-bay and see what i can find
