What's behind? What is the difference between SLR and SLR?

Digital back, also known as digital camera back, consists of image sensor and digital processing system. Compared with ordinary digital cameras, the biggest difference of digital back is that it has no lens, shutter and other structures, and can only be attached to other traditional cameras for use.

The digital back is mainly attached to a medium format camera or a large format machine, so that the camera that originally used film can also take digital photos. Compared with SLR digital cameras and portable digital cameras, digital back cameras are bulky, relatively inflexible and expensive, but the pixel level is often very high, and the area of the image sensor is also very large, and the imaging effect is amazing. These products are mainly used for demanding commercial photography and advertising photography.

There are 500 to 60 million pixels, and there are as many as 80 million pixels. The price is generally tens of thousands to hundreds of thousands of yuan.
