The wireless connection I use with both my 5D Mk4 & 1Dx2 to connect to my iPad cannot be used to transfer RAW files. JPEGs are transferred instead. Plugging in the SD card from the 5D through a SD to lightning connector allows me to import RAW files which I can then add to LightRoom & edit. Problem is, the 1Dx2 does not use SD & I cannot find a lightning CF adaptor to use. Is there one? Or better still, when will I be able to transfer RAW files wirelessly? This means I cannot use my 1Dx2 on my upcoming travels!!
