When choosing a card for the new Sony FX3 camera, I found this one. In fact, it turned out that it is capable of something that even cards twice as expensive are not capable of. In particular, recording in 4k 50 frames per second 4:2:2 10 bits, and even with the simultaneous recording of proxy files. Sandisk 300MB / sec is not capable of this - it can do the same, but the proxy no longer pulls out, while it costs twice as much. Well, the presence of a card reader as a gift is a great addition. Moreover, the card reader turned out to be very efficient. The speed through it is really higher than through Transcend with USB 3.0 Therefore, I consider this card an outstanding find!
