The end of 35mm adapers and hv20s....

I wonder if it is consistent, like -5.0 is 1/4000th and +1.5 is 1/25th. I wonder how you would be able to figure it out. During playback, is there any meta data showing up about f-stop/shutter?

GOod idea. Let me remember how to activate the information tab on playback. I turned it off and can't remember where the hell it was.

Edit: Nope, it does not display what shutter or anything the footage was shot at on the LCD. In fact, it only reads [ISO] for the video playback but does not say WHAT ISO it was at. That further leads me to believe that ISO is an auto function in movie mode.

So...what is the application for this. You can dial in your own aperture, and it sticks, good. You can dial in your own shutter speed with easy exposure adjustment, good. But what about ISO/gain? Is that still fully automatic? Or can you turn off auto gain? If it was automatic, then I guess you could also use exposure compensation to bias the gain in the direction you want (creative situations won't always warrant the auto exposure result). Or you could turn off auto gain (somehow) and set it manually, but how?

Yup. I'm probably wrong, but I'm almost certain that the camera is using auto iso/auto gain in LV mode for video. Because, it wouldn't effect the Still Image at all given that the settings that you've selected would ovveride auto. As they do, because I can take a still image with the exact settings I want regardless of what the LCD displays.

I.E -- Shutter @ 1/1000 produces a dark image even though the LV screen says there's plenty of light.
 
After having read this entire thread over the past days, I had to sign up now. Considering that numerous members have received their D90s it's surprising how little info we've gotten so far. Why does nobody resolve the confusion?

Honestly, I don't see why you wouldn't be able to manually set aperture and shutter. The D Movie mode section in the manual may be slim, but that's probably because all of the settings are explained in the photography section.

Somebody with a D90: Please select manual mode on the selection ring, and set it to a shutter of 1/50s + widest possible aperture. Set ISO to 200 and turn off Auto ISO. Lock the exposure, walk out into the sunlight and shoot a clip.
If the settings work, the clip should be:
-> considerably overexposed
-> not show any of the ol' Gladiator strobing

Wow, at least that range is the range of shutter speeds we'd expect to be available in movie mode for the most part.

If 1/4000 is -5, then -4 is 1/2000, -3 is 1/1000, -2 is 1/500, -1 is 1/250, 0 is 1/125, +1 is 1/63, and +1.5 is 1/47 and could very easily be 1/48 instead. Hmm.

Add to this test: start outside, and not indoors, when you set the shutter speed and lock it down.

Auto ISO has been off for me. I know that it seems logical that you can set this stuff, lol, but just throw the logic out the window, man.

I think +1/5 is somewhere around 1/24ish because it's acceptably smeary. Somewhere about +.3 would be about 1/48ish I bet.

Another question is what is the equivalent ISO range of the gain in movie mode? What is the lowest sensitivity? Maybe 200? 100? Less even? How about on the high end? 6400? Less? More?

Is + 1.5 always 1/24th smeary? Do you notice that at 0 EV it seems to be at the same shutter every time regardless of light conditions?

L01 is the lowest ISO setting. Hi1 is the highest. You can set the Auto ISO to a certain hi-ISO... hmm I wonder if you purposely activate the auto ISO then LIMIT it to a 200...

Hmm. I'm no movie expert but does it make sense to even allow 1/24th? If 1/24th is the lowest then shift everything down a stop, meaning 1/2000th on the high end. That is if it is hard mapped and not relative like normal exposure compensation.

Yeah I know, for still images. 100 to 6400 (200 to 3200 guaranteed). Since much of the still stuff doesn't translate over to movie mode, I wanted to know what it seems to be doing for gain.

someone just call nikon

I called the pre-sales tech line last week and the guy said his department hadn't received their D90s to play with yet. But I would be willing to call again. He was very helpful and was curious for the answer of all the questions I was asking...

Trying to figure this out now. It looked like so on the first pass, but this thing is so confusing to me that I'mgonna start triple checking.

I know though that it does change the read-out in A-mode so that's a start. And, I do see the effects of the shutter changing when I do suck with an Auto lens.
