I'm new to photography and I am running into a strange issue. Maybe I am taking the pictures wrong? I don't know but maybe you can tell me. When I take a picture with the Nexus 6P and preview that picture on my phone or my desktop PC, I can zoom in without the picture becoming pixelated. However, this is not the case with the Sony A7S II. Pictures on the A7S II seem to get pixelated much faster when I zoom in for a desktop preview. What gives?
