Via the Chinese Xitek Forum.
A browse to their product list reveals that they used to build only small sized sensors but suddenly they have made an APS-C in 6um for the pixel size! :-o
Anyway, it is always good to see more players entering into the market for producing sensors such that there are more choices, for the manufacturers and ultimately for we end-users and customers.
As for the specified Dynamic Range (DR) performance in 65dB, it is not too bad as it is equivalent to a maximum of 10.8 EV steps for the DR.
