I'm really enjoying the Sony A7III so far but the more I use it the more I find little things that bother me about the the camera. First and probably the biggest issue I have with the SOny camera is the colour science. The colours just seem to be off. The skin tones of models is just off. And the camera's ability to adjust the colour temperature accurately when in AWB mode and moving between sunlight and shade seems to be really strange. You can see in the first video when I shoot Jisel Lynn in the shade and then in full sun her skin tone changes. I also test video in the first video. I'm not a videographer but from what I've been able to figure out the auto focus does not work well at all with the adapted lenses. Auto focus also seems to have issues from time to time when shooting stills but that problem can quickly be fixed by switching the camera on and off. However, if you are planning on shooting live events with adapted lenses it might not be the best especially if you are shooting an event like a wedding when you CAN'T MISS shots like the first kiss.
This is just a basic review of my experience so far. I'll be making a video with a full review soon.
