What's the difference between Sony Black Card 1 and Black Card 2?

M2 is a north exposure sensor, which is clearer and improves high sensitivity. M2 has added wifi, which is still very practical. However, because the size of the sensor has not changed, the definition will not change substantially. Don't listen to the upstairs. If it exceeds 1000w pixels, the definition has little to do with pixels.

There are three things I don't like about m2. First, it's too expensive. The second is to flip the screen, which is a moving part, and the weak link is easy to break. Third, there are hot shoes and small cards. It is estimated that no one uses an external flash, which is pure waste and ugly. However, it is worthwhile to have a high-sensitivity sensor, wifi sensor and back-illuminated sensor. I think if it's too expensive, it's worth waiting for it to be reduced.
