I have been over on the A7 thread since I haven't been shooting my m4/3 cameras as much after buying a Sony FF body. There are lots of amazing photographs and photographers over there, but your images are an in-the-face reminder that the equipment is truly secondary. Perhaps some of your photos would be marginally better on some esoteric technical level with a larger format camera, but that wouldn't really improve them one bit in any meaningful emotive way. The magic is all yours, not your equipment's!
