Nikon D2X

the pdf lists this:
Picture Angle:
Full Image: Approx. 1.5x focal length in 35mm [135] format equivalent
High Speed Cropped Image: Approx. 2x focal length in 35mm [135]
format equivalent


So i know what the normal 1.5x crop would be, any ideas what the high speed crop means?
If its only using the center of the sensor, i guess the resolution would be lower too, but with 12mp i guess you could afford to lose some.

To achieve 8fps they have created a "second shooting mode" of sorts. Smaller MP images which will allow for higher frame rates.

that blended exposure seems such a stupid idea ... the only time it might be useful is if you were shooting multiple long exposures and you did not feel like using burst. But I don't know the capabilities of the blended exposure mode.

Anyway, tight cam.

[TQ] -- that picture you posted, that's one of the few Nikon shooters I have seen at sports events! People will not be switcing over to Nikon just because they realized a new camera ... in general, many people who would buy a D2x have already invested 5 figures in their canon gear.

Your right, i missed the "people" in that post. :(
 
After the D2h kind of disappointed me in it's overall performance, I'm curious to see how this one will turn out.

Either way, I'm not interested in the pro DSLRs yet, but I may get a 20D around xmas.
 
12MP with a 1.5x multiplier. That's got to be a noisy camera. Those are some pretty small photosites.

Kodak's 14MP full frame imager was a disaster.
 
well, that might just be becuase the kodak sucks lol

after all canon put 11mp into a full frame sensor sucessfully... i doubt 3 mp would go from good to horrific... and i dont doubt they can push many more mp (22 mp 1Ds Mark II anyone) into a full frame sensor without the horrible noise and terrible write times of the kodak

I think its quite possible 22mp in a full frame would work... but not yet. Nikon's putting 12.8 mp in to a 1.5x cropping sensor, and so that's a pretty similar pixel density overall. If someone pulls it off, putting >20mp in a full frame and achieving good quality, it's going to be Canon, maybe Nikon. That's my guess anyway.

The Kodak saved about $2g by not putting an AA filter in their camera, but they also skimped on the body and electronics, including noise processing and other image processing activities which resulted in the poor transfer performance. There's nothing to stop a 22mp camera from writing quickly assuming the cards are able to handle the transfer, it just will require efficient processing, something Canon and Nikon are both good at.
 
It's not quite that simple...

The Canon 1Ds is capable of out resolving most lenses. There aren't really any wide angle lenses that are good enough even to make use of the full 11MP the 1Ds has. Some of the L series telephoto lenses are still good enough.

At some point the imager will outresolve the nearly all lenses you can get for a given platform. Once you factor in noise from the size of the photosites and my semi-educated guess tells me that the practical limit is probably somewhere around 15-16MP in a full frame imager.

Assuming they can keep the noise down, which is somewhat doubtful, 12MP with a 1.5x crop factor has to be pushing the limits of the nearlly all the lenses.

Im thinking the noise is going to be pretty bad, they listed iso 800 as the max iso with 1600 and 3200 available when expanded to them, somthing is up with that.

While this is completely true, it's not going to stop them from trying. They've released DX lenses with the theory that they will support pixel densities higher than average on the smaller sensor.

The problem with pixel density, and thus photonic sensitivity, is a moving target. Each year the technology and efficiency (and to an extent processing) improves allowing the pixels to be packed tighter and tighter. There's equations that you can use to calculate the loss of efficiency (and they're pretty logical), but they don't work across different sensor designs. Different fab methods and refinements in the process will push capabilities further. I however don't think we sould necessarily expect to see much return in quality beyond twice the resolution of the 1Ds for example. At some point we can keep shrinking pixels but performance will have to drop off sharply and no amount of technology will improve it. I think the curve is going to level out before too long, and the methods as we know them now won't be able to go any further.

At least that won't be too big of a tragedy because the resolving power will have exceeded film, never mind the fact that current camera can out-resolve many lenses.
 
Image quality and all that aside, there are some other neat things here. I found this information here (scroll all the way to the bottom, then up about a half page):


External GPS units that adhere to the NMEA 0183 specification are supported (the new MC-35 adapter cable, which connects to the 10-pin remote port on the camera and provides both an RS-232 serial port and 10-pin remote port, is required); latitude, longitude and altitude can be stored in a photo's metadata. The D2X's date and time can also be set automatically when a GPS unit is connected

That is sweet. This had been on my mind since I saw the same basic idea brought up on Slashdot.
