New CMOS sensor by Sony...

Dear fellow night-sky explorers,

I have been keeping an eye on CMOS developments and have noticed that a few days ago Sony released a new 12mp sensor - IMX253.

Unless I am reading the specs incorrectly, the new CMOS sensor seems to be significantly more sensitive than ICX814 (915mV vs 660mV at F8), in spite of having a tad smaller pixels than the above mentioned CCD sensor (3.45microns vs 3.69 microns). I know that ADC is only 12bit and that the pixels are tiny, but if read noise is low then perhaps things are developing in the right direction?

Specs for IMX253: http://www.sony.net/Products/SC-HP/n...253_255_e.html

Specs for ICX814: http://www.sony.net/Products/SC-HP/c...814alg_aqg.pdf

Quite interesting. The read noise would have to be considerably lower for it to be worth while dropping down to 12bit.

Ah excellent

The sensor is a half decent size too at 17mm. One question will be whether or not it suffers from amp glow like some of their smaller CMOS sensors.

I guess we won't find out the specs we care about until somebody puts it in a camera, but it looks promising.
