D400 - III/V semiconductor Sensor
Sep 26, 2010

Well I think all of the D300 users should be excited, given that it has been 3 years since the introduction of the D300 with its 12M pixel sensor, at this point any D300 replacement will need to be spectaular...

It should be clear that no top of the line camera can now be released with less pixels that the Canon 7D and really being the same - is well kind of boring marketing.

Therefore - expect the D400 to be built around a next generation symmetric drive, III/V semiconductor sensor > 20M pixels.

These III/V semiconductor sensors will likely be based on a multi-junction design - either dual or triple junctions for maximum efficiency. III/V semiconductors are much, much faster than CMOS enabling very fast shooting intervals and high frame rate video. It is possible they may offer 2k video (2,048 pixels of horizontal resolution)

III/V semiconductor devices offer > 10db of noise improvement and dynamic range over CMOS, they have been expensive and difficult to build, it is the volume manufacture of these devices that has driven the D400 schedule.

These new devices will offer a level of dynamic range and noise performance, not seen since film.
