but 1 XQD and 1 SD is better than 1XQD...
I find their excuse for not at least having an SD card (too slow) to be BS. The D500/850 have the XQD/SD combo. If you need max speed you can remove the SD card, but if you're shooting a critical event that warrants a backup option you can pop in an SD card.
Absolutely agree. Besides, while they're a bit slower, the 300mbs SDXC card in my D500's second slot has no trouble backing up the XQD card in slot 1.
This all points to how much an geared-to-amateurs forum DPR is. Some of us F/T and P/T pros rely on the card in the second slot to provide a redundant backup, it's part of our workflow. I have had a couple of occasions where a card failed in slot 1 and had to rely on the card in slot 2 for client proof delivery.
Not only pros (although I was one many moons ago, long before digital), but there are those of us who are now at the point in our lives that trips to marvelous places are probably the last time we'll be there.
I've no intention of shooting with a camera that doesn't let me back up what are literally once- or last-in-a- lifetime images, no matter how slim the chance of a card failure.
After all, I don't expect the plane to crash, but I still get flight insurance.
