What is a stacked lens? What is Zeiss?

Stacked lens should be stacked CMOS sensors (ExmorRS), which was officially released by Sony on August 22nd, 20 12. This kind of sensor will be mainly used in mobile digital devices such as mobile phones and tablet computers. EXMORRS stacked CMOS sensor is developed from back-illuminated CMOS sensor. The new sensor will put the circuit part that needs to be close to the photosensitive element under the photosensitive element, so there will be more space inside the device. While realizing functional diversification, it also realizes miniaturization. The sensor uses a new RGBW color coding method. Different from the traditional RGB color coding method, the W white pixel sensor built in the sensor can independently process the brightness signal, expand the sensitivity range, and improve the image quality of the sensor in low light conditions without damaging the image quality.

Carl zeiss is a German brand and one of the few non-Japanese optical lens manufacturers. Carl Zeiss is a manufacturer of optical instruments with a long history, and its lens has always been synonymous with "nobility" in the field of traditional cameras. Carl zeiss has a history of 100 years and produces one of the few high-quality lenses in the world. Because of its unique color reproduction and imaging characteristics, photographers and enthusiasts all over the world can't put it down (but stay away from it because of its high price). High resolution, excellent color reproduction and almost no corner distortion. Faithfully provide high-quality photographic works. Now carl zeiss and Sony have jointly produced Sony A-mount high-performance SLR lens, named ZA lens.
