Just got the Sony A7R4 about a week ago. It’s a big upgrade for me over the MKII version, so I’m quite excited to have it and start testing it a bit. The files definitely give you that medium format feel with the increased resolution. I took it out to Dr. Park in Fox Point, WI this morning and took some shots. There was quite a bit of haze and humidity in the air, so the sun was like a nice round ball in the sky at sunrise.
