Doesn't temp have a big impact on noise with CMOS? If the 5 minute limit is due to overheating I wonder if we'll see rising noise levels over long shots.

Hi all. My first post. I just jumped in on this D-90 thread and I must say, I'm likely to buy it. I've been promising myself a new digicam for a while and being as conservative (stingy) with the $ as I am- I have no excuse not to jump on this gem and Hi-Def Vids to boot- Woot! After all, the D-90 will replace my previous Nikon digicam...
that cost me $1000 in 2004...
That's the Nikon Coolpix 5000- believe it or not.
Do you think the D90 will help me make better pictures than these....

I hope so ;)

What is the mutilplication factor?

I wanted to buy a brevis, but I will probably go for the D-90 or the next camera Canon or Nikon with video mode.I have already lenses Nikon and Canon.
And No loss of light comare to 35mm adaptor, but I am wondering if their is a multiplication factor.
The 5min don't bother me because thats what I shoot in video usually.
Now I am thinking of selling my Sony A1u and buy the D-90 plus a second Sony HC-5(they are $500new in montreal these days) and I wil be able to do 3 cam set up.
For the audio edirol,zoom or tascam recorder or my Macbook pro with usb mic.

x 1.5 (the same as other DSLRs)

The no light loss is very good, as is not having to buy a flip module to get the image the right way up and no bad vignetting in the corners and no grain at high shutter speeds and edge to edge sharpness and 4:4:4 colour ! (depending on the M-Jpeg compression used) etc etc . . .

But if you can only shoot 5 minutes because the sensor heats up (this is what Nikon claim) then you might have to wait for 10-15 minutes for the sensor to cool before the camera will allow you to shoot some more - could be problematic if true - but currently just speculation.

" because the sensor heats up (this is what Nikon claim)"

Lee, where did you see this? I can't find anything by Nikon that explains the need for the runtime limit.

I can live with the 5 minute limit and the waiting time

Lee
I remember that astrophotographer used to or maybe still does cooling the ccd's
to have less noise.I live in a place cold 6 month per year and it may help me(for the 1st time).
Or I need a second D-90, so by the time one cam cool down the other shoot, so longer film in the end!

I forget now, in a 'hands on review' - they went on to say that they think the real reason maybe that above 5 minutes the product is considered a video camera and would incur greater tax burden - but this idea has also been questioned.

Actual original, straight from the camera no additional compression footage: (download the original source file - bottom right - you need to join Vimeo to do this - it's free)

Would be interesting if they can eventually get HD video out of the unique Sigma DSLR...

Cineform capture of the HDMI signal on D90

If someone can pass on David at Cineform a camera, he is willing to do tests to see if the HDMI signal (1080i) can be captured..

Anmol -- It uses the Foveon "direct image sensor", which uses three layers of Pixel Sensors (one each for absorbing red, green and blue light). This avoids use of (or the need for) a mosaic pattern scheme (which involves colour interpolation). As far as I know, Sigma is the only maker to adopt it, so I called it "unique"!

Interesting. I watched the Duck one and it seems that the shutter speed is a bit too high and iris a little hot. What was your shutter speed and other settings?

Looking at the top MOV file (what kind of bird is that anyway?), there's definitely some exposure hunting going on.

It's still not clear if the exposure level can be locked and solid.

Well, I have some raw footage from this camera. It's safe to say that HD camcorders will be safe for a few more years. The compression used in the D90 is quite bad and certainly won't be useable for things like short films.

Oh well, it was exciting for a short while. It will be Interesting to see how future SLR's develop the video option though.
