    Caleb Rasak got a reaction from neosushi in New Fairchild Sensor - Same DR of the Pocket and Cinema, but in 4.5k   
    Found this post on BMCuser and wanted to bring it here. Hopefully BM will introduce this sensor tech into new cameras down the road the specs look incredible.

    "Fairchild Imaging, the maker of the sensors in both the Pocket and Cinema Camera, just announced a new sensor on the front page of their website, the LTN4625A. Preliminary data was found here:http://www.atdelectronique.com/our-offer/bae-systems. 

    It looks like it will have the same dynamic range of the Pocket (14.5 stops), but it does so using a smaller pixel size of 5.5um (the Pocket and Cinema have a 6.5um pixel diagonal.)

    This is huge. The CMOSIS CMV12000 sensor in the Production and Ursa cameras also have a pixel size of 5.5um, but can only do about 9.9 stops. This Fairchild sensor would be sucking up over 4.5 times the amount of light. 

    The Fairchild sensor is also bigger, and arguably much more usable resolution-wise than the CMOSIS. The Fairchild maxes out at 4608 x 2592, which is a 16x9 ratio. The CMV12000 maxes out at 4096 x 3072, a 4x3 ratio (although only 4000 x 2160 is currently being used in the Production and URSA in raw).

    The new Fairchild sensor would be a true Super 35mm size, with a 29.08mm diagonal at its maximum resolution.

    The Fairchild is also speedier. The CMV12000 can only do a maximum of 90fps with full image quality (URSA currently tops out at 80fps.) The Fairchild is listed at 240fps.

    I have no idea when Blackmagic will implement this and in what final form it would take, but I would wager a guess that it is only a matter of time. This is a very attractive video sensor, and something I've definitely been waiting for from the company."

    Caleb Rasak reacted to dsavage in Panasonic GH4 4K Production Diary – Day 3 – Shootout!   
    Looks like the 5D Mark III is still the lowlight king, but I'm impressed with how well the GH4 footage holds up to being denoised.  Curious to know if this was Neat Video or something else.
