The fact is always that in any manufacturing run consisting of thousands of cameras, there are going to be few percentage points worth of bad units.

Absolutely correct. You're describing classic blooming caused by a combination of point light sources, lens optics and sensor physics.

True, but all such expansive creative exposures should at least respect the engineered limitations of the lens, sensor and CPU combination. Sometimes, blooming and flare is used as part of a creative composition. Usually not my style or anywhere near my personal tastes though.

Let's just say we don't agree on the creative assessment of the photo. It's terrible in my opinion. Aim a camera & lens - any camera & lens - at a series of bright point sources of light and I guarantee you that I can make an exposure that will drive that camera & lens into all sorts of problems. This is a game that owners of new equipment inadvertently - inadvertently - play to test the limits of the hype/PR which precedes the release of the equipment. It happens with new high end speakers, microphones, amplifiers, lenses, cameras, cell phones, and you name it. The device may be working as designed, but people find all sorts of interesting ways of stepping outside the design parameters. Taking photos in pitch black, handheld, with little else but point sources of light with the expectation that the lens and sensor combination will somehow capture a natural exposure. When I overdrive my power amp into clipping, the audio is still listenable, but it is by no means anywhere near as gorgeous sounding as when I drive the amp within its sweet spot. The amp's sweet spot is actually huge. The D700 and D3 sweet spots are huge. My sample photo shows what the camera can do, and that was just a shot I made to check exposure! The final shots had even better range, much better composition and so on - all dead clean.

Nikon says the exposure is terrible (I'm paraphrasing obviously - Nikon is not that crass), several pros who've seen the shot say the exposure is terrible, and I my opinion is also that the exposure is terrible. Sorry, but snapshots are snapshots, in this case unworthy of analysis because they push beyond the limits of the camera & lens combination. You want to be able to just pick up a D700 on full auto and snap away under any crazy lighting conditions? Me too, but we both know that good photography is not that simple. If it was, everybody would be doing it.

I don't account for it. The argument or case for this so-called issue is specious. A lens/sensor/CPU combination in one camera will always yield different results than the same lens with a different sensor/CPU combination. The angle of view is slightly different, angle to point sources slightly different, X/Y position is different, etc., etc. Show me rational exposures instead of bedroom shots directly at bare ceiling mini-floods in an otherwise darkened room. Does the absurdity of this so-called test escape everyone?

S'cuse me . . . THIS is the horrible bedroom exposure shot directly into a bare ceiling mini-flood. It's dopey, an utter waste of time, and a test of nothing except the photographer's lack of knowledge. I love the audiophile analogies - sorry - but how about if I turn my speakers to face a curtained window and then complain that the speakers suddenly have lousy stereo separation. These cameras were not designed to be aimed directly at point sources of bright light at such close proximity and still be able to magically balance the rest of the scene. The church shots are not much better (as Nikon indicated in its response).

Answered above, but my opinion is that all the example images are terrible. Useless as tests, useless even as casual snapshots.

Blooming isn't an issue. My example shows that quite clearly. The D700 and D300 are both fine cameras when matched with all sorts of different lenses. The only 'gotcha' is that the photographer wielding either camera has to make a proper exposure which expresses the composition, lighting and mood he wants to capture. Sometimes, a simple point & shoot snapshot on full auto isn't going to cut it in difficult lighting and extreme dynamic range subjects. The D700, like any other great camera, has to be properly setup for such difficult scenes. The only thing I've managed to eke out of the blooming examples is that a couple of the photographers are being arch (trying to see exactly how outrageously the D700 can be pushed), at least one doesn't know how to expose a scene properly, and one doesn't understand the basics of lighting and composition. But maybe this assessment is too harsh? Maybe some people, excited about their new D700s, are just snapping away at everything in sight and then reacting very badly when, inevitably, some exalted (and unreasonable) expectations aren't met. I certainly sympathize (empathize?), but there's nothing at all wrong with the D700.

Technically that's a bit hard to do and I'm a wee bit too busy to undertake the creation of an accurate reproduction of the scene in question. I'm sure you understand. But I also understand the spirit of the request. I intend to grab some high ISO night shots in front of St. Paul's or St. James' Cathedral in downtown Toronto on Thursday night (weather permitting). If I get the shots, I'll post something here and bring it to your attention.
