You should also know that the performance of the adapters is fairly poor. Unfortunately the one I have (Delkin) is a type 2, so can't compare the 5d3 direct SD performance against an SD inside an adapter, however I suspect the one in the adapter would be roughly 30 to 50% slower based on the same in a 7d.
Ah, I was wondering if that was the case. But 30-50% is much worse than I would have expected. Thank you.
Are you not taking a laptop/tablet? If so just make sure you have a reader and store the contents each day.
I'm taking a laptop, but that doesn't help in the scenario where a card fails while I'm out shooting. Hopefully the Sandisk recovery software would get my pictures back, but I've never used it, or seen much commentary on it. I'd hate to lose a day's worth of shots. And before anyone asks, no, I'm not planning on taking a laptop on my hikes
For a bit more detail, I'm heading out on some of the 'grand circle' in Utah/Arizona, and many days I'll be out before dawn, back after sunset, and will probably have hundreds of shots a day between downloads. Murphy's law tells me this will be a perfect time to have a card fail on me
