What's the difference between Sony's α7k and α7r?

The difference between Sony's α7k and α7r;

1. The borders and focusing accuracy of the two sensors are different.

Sony a7K is the abbreviation of Sony a7+E2870 lens group. Sony a7 is a 24-megapixel Quan Huafu sensor and a7R is a 36-megapixel Quan Huafu sensor. Compared with a7R and A7R, A7R is mainly different in that the frame of the sensor is slightly lower, but the phase difference focusing is integrated on the sensor, that is, the focusing adopts a mixed mode of phase difference focusing and contrast focusing, which not only ensures the focusing accuracy, but also improves the focusing speed.

2. Their target customers are different.

Relatively speaking, the pixel CMOS of a7R is higher, which eliminates the influence of low-pass filter on the picture and is suitable for landscape photography with higher resolution requirements. Although the pixel of a7R is slightly lower, it integrates phase difference focusing on CMOS, and the focusing speed is slightly faster than A7R, which is suitable for customers who have requirements on focusing speed.
