To whom it concerns:
My old 30 pins camera connection kit (sd card reader and usb cable interface) didn't fit in the new lightning connector, obviously. Now Apple sells two separate ones for twice the kit price. So I tried the '30 pins to lightning adapter' for once the price. Results were mixed. The sd card reader (sd card might be faulty) didn't work, but the usb connection to the camera worked perfectly, with nef raw files, don't know about jpeg.
And of course iPad only, no iPhone
