Well, this is all speculation imho.
I dont see Pentax replacing the 645D so soon, as they have said it in last CP+ interview...

@672 : what is your opinion re. SMC 67 M*800/6.7 ?

P67 800mm

The 800mm is a really great lens. I reviewed it a about one year ago here in the forums under lens reviews. For image quality its the best super telephoto i have ever used. Its big by stills standards but its worth the extra trouble. No chromatic abberations, ever. Can be shot wide open , which is 6.7 and it looks great . For less $$$ and much lighter the P67 400mm is a really really great lens. Similiar performance to its big brother in a smaller package. I also have a P67 600mm f4 converted to K mount and its got all kinds of abberations and color fringing . Its just taking up space in my closet now. I am sure it was great in 1970 with black and white neg, but doesnt do well in modern times.
With the 800mm i bought a Kata TLB800 back pack , what a mistake, it was clearly not designed by people who actually lug lenses around. I had to mail order it, so did not know until it arrived that when the lens is fastened into the pack for travel it snugs up against the far wall of the pack, meaning all that weight is centered six inches away from my back instead of right up against the pack wall nearest my back. Its totally backwards.....
