Sony to develop Super-35mm pro camcorder
Sony Corporation announced today that it is developing a new type of E-mount interchangeable lens camcorder for professional use that is equipped with a Super-35mm equivalent large format CMOS sensor. This new addition to Sony’s professional “NXCAM” line will be available in the middle of 2011.
Editor’s Note: Super-35mm is not full frame 35mm. The 35mm movie format is what we call half-frame in still photography, or a little over 18 x 24mm – a size very close to the nominal 16 x 24mm of the DT/DX format used by Sony for APS-C sensors. Sony may decide to use a normal APS-C sensor for this, or to use a true 16:9 ratio for HD Video. However, Super-35mm normally means a squarer image format. No doubt internet forums will be full of folk claiming that Sony has gone full frame frame on the E-mount just like they said, etc etc – well, that is not the case. Super-35mm does not mean full frame (technically, double frame 35mm).
But this sensor may be significantly larger than existing APS-C, at a possible 25 x 18.5mm rather than 23.5 x 15.5mm or thereabouts (please note that one APS-C sensor is already quoted as being 16 x 24mm). Alpha A-mount lenses will of course cover this easily; E-mount NEX lenses may have been designed to do so from the start, though it may be pushing it to expect corner quality unless OS is disabled. By definition, all OS-type lenses must have a larger circle of coverage than the format they are designed for – often considerably larger. Turning off OS would enable any properly designed OS lens to cover a bigger sensor without any corner vignetting or loss of sharpness.
