OK I want a 1920x1080 CCD camera with 2/3" chips AVC Intra 100 at less than £15k but I know that I aint going to get one so cmos is what we have to accept.
The value of kit was easily written off in the past but as broadcast in the UK is in decline and budgets are just not there for most programming I can not right off kit the way I used to.
The manufacturers need to realise this too as we can not invest £50k into cameras anymore for most production.
The same goes for post prod and the desktop solutions will become more prevalent than the high end bespoke hardware.
A CMOS isn't going to drop the price any. A 2/3" chip is a 2/3" chip, same price. All you might see is 5-10% decrease... simply because a CMOS uses less silicon, but at the cost of pixel size.
http://www.dalsa.com/corp/markets/CCD_vs_CMOS.aspx said:CMOS cameras may require fewer components and less power, but they still generally require companion chips to optimize image quality, increasing cost and reducing the advantage they gain from lower power consumption. CCD devices are less complex than CMOS, so they cost less to design. CCD fabrication processes also tend to be more mature and optimized; in general, it will cost less (in both design and fabrication) to yield a CCD than a CMOS imager for a specific high-performance application. However, wafer size can be a dominating influence on device cost; the larger the wafer, the more devices it can yield, and the lower the cost per device.
The CMOS does A to D conversion at the pixel level, and thus doesn't need additional space (additional silicon) to read out the image. But you're compacting the space of the photon collector and the a to d conversion into the place of where you could place a single larger pixel.
