I wrote about the Sony A7S II and Lexar SDXC a few weeks ago and there was definitely interest in the topic of SDXC cards for 4K video. So I’m posting again with a title to that effect, and with an update.
On my recent trip I used two cards to record 4K video on the Sony A7S II and A7R II. Both worked flawlessly.
First, I filled the Lexar 64GB 2000X card to capacity, then continued using the Lexar 256GB 1000X card. But I lost some video because I was doing a selfie “how to” and the A7S II did not warn me (I kept on talking for another 8 minutes or so!). So from now on it’s 256GB cards only when shooting video.
I prefer the 64GB card because it is hyper fast at downloads. But 64GB is a bad idea for 30P/100M 4K video; it’s too easy to run out of space at the wrong time. And Sony mirrorless sucks in using card speed; it doesn’t matter between the two (the camera is not a fast responder for saving or reviewing images). So the smart move is just to use 256GB cards if shooting video at all.
So I now use the about $142 Lexar 256GB SDXC cards in Sony mirrorless. The price is very reasonable, and the about $275 2-pack Lexar 256GB SDXC is even a little better deal. (Prices as this was written).
