I have two sony A7RII, and very evident that the last purchased, the time to write and read the memory card is much slower than in the first A7RII. at first I blamed the SD card, not fast, then putting the same card, the second A7R2II and always much slower, try with other equal card, reset same story. Any suggestions?
Have you got them using the same firmware and on the same RAW settings? My A7RII was swift until I updated the firmware and switched to uncompressed RAW. Don't get me wrong, I'm happy I'm using uncompressed but now my camera writes to the cards at a snails pace and I have some of the fastest cards you can get.
