Since getting this camera, I have found huge improvement to the quality of my photographs. So mush easier to resize and edit shots, allowing for high quality outcomes, due to the high number of Pixels. I can, when needed, zoom in and crop without getting pixelisation. Fabulous

I’ve used and owned a canon 760d, 7dmk2, 5d3, 5d4 and Nikon d800s and a d810. This camera somehow picks all the best bits from all my previous cameras and puts it into a robust mirror less format and then throws another load of MP to boot. Simply brilliant

This is an upgrade from my original A7 which was the best digital camera I’ve ever owned. The A7rm3 is a step ahead with a proper facility to stream live content to a PC or phone. Huge benefit with my astrophotography. Love it.
