G'day all. Whilst on my travels, I need an adaptor for the Surface Pro 4 to read my camera standard sd card through the micro sd port. I do not want to use a USB adaptor, as my prefered Lightroom workflow allows auto backup to a portable USB hard drive, which is plugged into the only USB port available. The MS multi-port assessories are too large and heavy for travel purposes. Can anyone recommend a simple adaptor suported by the Pro 4?
