I purchased an Eye Fi Mobi Pro 32gb after seeing a friend with a 5DMkIII using one. After setting it up and attempting to use it with an iPhone 6sPlus (jpg only to SD card) I am running into a problem with the speed of transfer and the number of photos that will transfer. I have tried the card on my daughters EOS M and it seems to work fine on that camera. Has anyone else experienced any problems with using the 5DSR?
