you can literally buy these and sell for 75+ on ebay when they arrive. But because doesnt say "SanDisk" on it. wont go hot I shoot weddings on 2 a7r3's too, often use the burst 10fps and never filled the burst. But i guess other types of shooters like sports may require faster buffer clearing. Although most that go for these cards, is to shoot 4k120 on a7s3/etc
That's true, but it's sod's law that the shot you want is the first one you miss. It's a great price, don't get me wrong.
a 200Mb card wont give you much more shooting before stopping. You get like 30-40 photos in the buffer, after that, 10FPS is about 1Gb/s on a a7r3. doesnt matter what card you have, after 50+ shots, they will all slow down to about 1 photo a second. Also worth noting that even though certain cards write at 100Mb/s, 150Mb/s and so on, sony cameras cant write to them at those speeds. for example a extreme pro, capable of 293Mb/s, only writes at a maximum of 141MB/s in camera. a V60 Tough, capable of 282, maxes at 129 in camera
It's not video that's the problem. It's photos. When they're 42mp and 80mb each, you really need fast write when you're snapping sway at fireworks or sports and the like. I swapped it for an R3 which has a much bigger buffer and UHS-II. Turned a very capable but frustrating camera into one that's a joy to use.
For video I don't know many cameras that write faster than this? A7r2 maxes as 100Mbps,thats 12.5Mb/s I recorded plenty of 100mbps on the slower v30 integral cards before without issues.
