Regarding the "Recommended Cameras" list below, don't forget that we're in the calm before a storm. Three cameras, all expected in the Fall, stand a chance of creating a new category (the < pro FF DSLR, previously the exclusive province of the Canon 5D). They might shake up the higher end of the camera market considerably, even affecting the lower end of the present medium-format digital back market.
Expected are the full-frame, high-pixel-count Sony A900; at least one new high-end, full-frame camera from Nikon (although whether it will be a smaller, "detuned" D3—the road version of the pro race car—or a counterpart to the Sony, possibly even using the same sensor—or both—I don't know); and a replacement from Canon for the 5D.
There have been various leaks, rumors, and "pre-announcements," most visibly from Sony, which anticipates a September release for the A900. I should state that I don't have any inside information—well, I don't have any real information at all, "inside" or not—and I'm not under any non-disclosure constraint. I don't know anything I'm withholding. But I'm going to venture to guess that this is a stressful, high-tension stretch of time for the relevant teams at the three manufacturers. They're all jumping on more or less the same market (full-frame, pro-am) at the same time. They're probably well aware that their new cameras are going to be competing with each other. There is probably great interest at each company in what the other companies are doing, when they're going to release, and what each other's pricing will be. Looming as a warning to complacency is what happened to the Canon 1D Mark III when it came out, when early problems created headaches and bad publicity for the company—nobody wants a launch before the product is truly ready, I'm sure! Long days and sleepless nights indeed.
I imagine it's safe to say that all three cameras will be shipping prior to next Christmas—that is, if they can be, given the constraints of what it takes to produce them. 2008 has been fun so far. It will only get better.
(A favor—please don't post links to rumors in the comments.)
UPDATE: Nikonrumors.com has posted specs for an upcoming Nikon D700 and Chasseur d'Images in France has seconded the rumors. A July 1 intro date is being bandied about. The specs show a smaller, lighter camera with the D3's FX (full-frame), 12.1-MP sensor—pretty much the "FX-L" I wrote about here.
A digital F100? Looking like it. And if so, bravo. (Thanks to Andre)
Featured Comment by Geoff Wittig: "Popular Photography reports this month that manufacturers expect to sell 9 million DSLRs in 2008. This will exceed the peak year of 35mm film SLR sales (8 million) in 1984. A large majority of those DSLRs will be entry level cameras, but there's a 'halo effect' for a high-end full frame camera; enthusiasts are more willing to buy into a system that has a top quality flagship camera than one that places a ceiling on their future aspirations. (Mind you, we're talking about perception here. Seems like anything much beyond 16 megapixels for now exceeds practical utility.) Nikon and Canon already have street cred., but a circa 25 megapixel Sony will make the former Minolta line a lot more appealing to first-timers. Just my 2 cents."
