If the OP wants fast transfer, taking into account everything (like removing the card and working with it on the computer) then consider tether transfer via USB cable and/or wifi. Newer cameras like my Oly, as I noted, transfer over AC wifi so it's not instant, but I don't have to do anything and it happens while I'm setting up another shot, etc. And I don't trip on the USB cable.
Both my Canon and Oly allow for designating a folder for the images to go into. I don't use Photos, but you can set up a folder action so that any new images into that folder would be auto-imported into Photos (Hazel can do that IIRC). Photos doesn't do tethering like other photo management applications do, unfortunately.
