A drawback to this backup method is you can't as easily do initial editing while in the field. But I guess if you go with the slower and cheaper SDXC, you can save a lot more. For example 128GB UHS-II SDXC cost me $120 each but 512GB CFexpress (not the fastest grade) was only $180. My impression is that it's the CFexpress cards that are actually cheaper than the fast SDXC. I've just started looking into transitioning to mirrorless and bought some new memory cards to use with the cameras I borrow from CPS. IMO if you're looking for a backup option without hauling around a laptop or similar device, it would be a reasonable option. Less so for backup purposes, but I have done that as well. Yes, I have used this feature a fair amount in my 1D cameras for various reasons shooting events, etc. I use bigger cards now and don't have the same issues.ġTB cards sound like a lot of backup however, only you know how much you will shoot, or whether you have access to download your images. I always tried to empty the CF before it filled up, or if it was close, I had the camera write straight to the SD. If I had a fairly full CF card to transfer, I seem to remember this taking about 5 minutes, and then swap out the SD for a blank one. I never had a problem with the transfer, just the little bit of time it took. I did not originally have a CF card reader, and used to copy the files from the CF to the SD, and transfer from the SD. I started out using 128gb cards on the R5, a CFExpress Type B and a couple of UHS-II SDs. I'm stymied by some weight concerns and thinking about getting a few 1TB SDxC cards as secondary backup targets. Does anyone use the folder copy function from one card to the other?
