I rented an A7R2 and am trying to view the RAWs in Photo Mechanic. With my 5D3 shooting RAW I would see full res from the embedded JPEG. But with the Sony, I see a 1616x1080 image when I view at the "1" setting in the zoom area of preview mode. Is there a way to make use of my MacBook Pro 15 Retina screen and the A7R2 in Photo Mechanic?
