The user Mousehill was in the BBC Wildlife competition last year, where he got special mentioning in certain categories. And remained in field till the final places were assigned. He was recently accepted in a prestigious Dutch wildlife guild.
The year before, Pentax user Yuichi Takasaka, got Highly Commended in the BBC wildlife competition, for shot of hovering hummingbirds using high-speed sync-flash mode. (His shots are in the Portfolio 16, as I remember, can be bought at Amazon e.g.)
The Pro wildlife photographer, Andy Rouse, who has also used Pentax gear, got Specially Commended in the 2006 BBC Wildlife Photographer of the Year. His superb shot, can be bought framed (in a limited edition) at his site, for £160.00 GBP. (That shot was with Nikon or Canon though).
World acclaimed photographer Sebastian Salgado, is currently using Pentax 645N for his genesis project, of endangered species :
(He lives up to the old tale, how the best photographers don’t take time to make sites etc. they’re out working)
And one of my favourite wildlife photographers Mattias Klum, did a lot of his work for NGM with Pentax film SLRs.
I hope I get to see the exhibition one day too. I’ve subscribed to BBC Wildlife for a longer period of time, a great magazine. (I can recommend getting the portfolios with winning shots, they contain the info on how the shots were taken, also different settings and values).
Tom, didn’t know that you used to display here, a sweet site :

(What does he mean, in this link that he added canvas on the left ?)
The FA* 600/4 ED [IF] can be ordered new from Japan, and so can the FA* 300/2.8 ED [IF].
But I agree, with the current pace of technology; Pentax would be a tougher brand to choice for wildlife and fast pace action. A user on DPr was looking for the FA* 600/4, but ended up buying Canon, as it was so much easier and more convenient to get a hold of.
Though seeing the work from Walter, I was very impressed with the Sigma 500mm/4.5 EX DG. And there is also the Sigma 800mm f5.6 EX DG made in Pentax mount.
Edit :
The trigger cameras that are left out in the bush for weeks, are usually cheaper APS-C crop DSLR. Since these entries can win, then the IQ must be up to notch. They are framed in big sizes.
