I'm 100% sure the exposure is lockable. Its been stated many times.
The end of 35mm adapers and hv20s....

Yeah so it's still no 1080.. I don't get it then, to me that right there makes it not even an option. It's like going back a step.

I agree with you 100% - even though I think the exposure + rolling shutter can be overcome (worst case scenario you could post correct the exp jumps if there is no way of locking the exp - and avoid rolling shutter issues by careful camera work) - I still think the lack of detail and clarity - and not in a good 'film' sort of way - is a worse issue, for myself at least.
Basically you sum up my thoughts exactly ! Fantastic concept that I imagine will deliver something outstanding in the next year or so - but at the moment we would appear to have an 'ok' video function on a great camera.
Fantastic advantages like the large sensor - unrivaled low light shooting - and access to shallow DOF / Nikon lenses is somewhat let down by the poor quality of the final files.

The statement " Matrix metering is used regardless of the metering method selected." Means that that is the only metering method available when using the movie mode, not that the exposure isn't lockable.
I don't think the question is whether or not there is a button that is intended to lock the exposure, the question is whether or not that exposure locking button ACTUALLY completely, totally, 100% all the time, always, in every frame prevents the exposure from changing.
Based on the number of professional clips that demonstrate amatureish looking sudden jumps in exposure from frame to frame, I am not convinced that the exposure lock function actually prevents the exposure from ever possibly changing from one frame to the next.

Man 8pages since I went to bed. I think people are convincing themselves this camera isn't going to work because it's so bad ass.
Right! First thing I'm going when I get mine is to turn the ISO speed up to 800, shutter speed to 1/60 and see how that fairs for shooting.
Rolling shutters do suck, I know that Silicon Imaging "solved" this problem by increasing the frame rate to twice that of the shutter, and dumping the inbetween files to get their 24fps. Aka Silicon's camera shoot 48fps, and dumps every other frame. Or so I've heard.
Still can't wait for this thing! Anyone hear any new release date information? I preordered on the 27th from Amazon, but they don't have a shipping time frame like Circuit City and BH. :-(

I think people are looking at the evidence, considering what we know or have inferred (and the facts we have gleaned from Nikon, few as they are) we have made reasoned guesses and concluded that there might be some problems with rolling shutter, exposure locking, lack of clarity and so on.
I don't think anyone here has concluded that the camera is not going to work 'because it is bad ass'.

Thanks, Ryan.
I downloaded the D80 manual from Nikon's site (in glorious "No Print PDF"). Page 50, at least, suggests the D80 can be set to full manual. If you confirm that, I'll have more reason to hope the D90 can, too—it would be odd otherwise—& that the D90's Movie mode might follow suit.
If my last guess is correct, it would obviate all exposure difficulties for me. I can't recall the last time I used any automatic metering on my XL2, or any other mini DV cam.
It's a shame that all the video clips seen so far were shot with the modern AF lenses.
old fashioned manual AIS or AI lenses should help reduce exposure flicker (since there is no communication between lens and camera). hopefully, the camera does ship in 15 days and i can test my hypothesis with my 55mm micro AIS lens.

Well that would be two of us then.

Once again, in my 40X, which I am certain shares the same technology as the D90, Matrix metering means that it makes an exposure determination of the frame as a whole, it is not spot metering or whatever else. Once that determination is made you press the AF-L/AF-E button next to the viewfinder and both lock as long as you keep it pressed. You can overide the focusing manually and exposure remains locked but if you try to zoom it unlocks the exposure even if you are still pressing the button. I tried it yesterday and thats how it plays. I am sure it won't be much different in the D90.

I think the general consensus is that the lens itself does not open and close it's aperture 24 times a second or as many times as it needs, but something else is changing the apparent exposure - like ISO changes or gain etc.

The Auto Matrix Metering is changing the exposure. And I dont know how it will react to manual lenses.

Does the shutter speed change when you zoom? On my D80 it doesn't. The aperture changes, but that's fine. Aperture changes on most video cameras when you zoom. However, if the shutter speed changes in an attempt to match the changing aperture, then that's no good.

Perhaps the worst case scenario is it (matrix metering effects) will need to be corrected in post. Not hard, simply time consuming.
A small and fixable flaw. At least it's nothing un-fixable such as pulses in focus or something.

I just checked. A mode is for aperture priority so when you move the camera it changes the shutter speed and when you put it in S mode is for shutter priority and changes the aperture. So S should be the one to choose. And as long as I am pressing the lock button the selection is staying put.
BTW. Sorry, when I zoom in S it unlocks the F stop, keeps the same shutter speed.

I'm going to stop all my speculation and worries about this camera, and this blog and say that the d90 is basically like a Super 8 camera as compared to the RED ONE. I'm very eager to see the specs for the Canon 5d Mark II - let's hope that has a better shutter, high speeds of shooting, less compression and 1080p. Doubt that but I also hear Nikon is planning a much better version of this movie mode for March.
when doing stopmotion, the AI lenses don't communicate info, which minimizes (but doesn't completely eliminate) the subtle exposure flicker between each still.
however, what you said is true. which got me thinking. maybe nikon hard wired the auto everything mode, so that no bad videos float on the net in order to hook the market. 98% of the market won't even notice flicker or Rolling shutter. All the soccer moms and all the dentists with too much cash will only focus on the amazing colours and sharp image of their kids or gf's.
When the d70 came out, it was almost impossible to take a bad picture with it.
even for a complete noob like myself. D70 was first camera. when i (along with others upgraded to D200), pictures looks like dreck in the hands of amateurs. Massive outcry on the net denoucing the camera.. What happened was nikon removed the auto magic module and the d200 required actual photography skills to make a decent pic.
Perhaps nikon will wait a year or so, being enabling complete manual control for D-movie.
