My brother bought this sony camera almost 6 month ago I used this camera for 1 month and I experienced that this is a value for money product which provides almost all features that a camera need to have. it's a a full frame mirrorless camera. It's not most cheap product but not a most expensive. its price almost 120000.
Sony A7 3 is a a valuable product which provides good picture quality and also good video quality. in this camera it's have 24 megapixel sensor which provides you a good picture and video quality. It's shutter speed is also okay. I took some pictures and videos by this camera on every fps and shutter speed I think ok it's work properly. Lens quality is amazing and resolution given by this camera is good for our eyes.
This camera have some cons also. its touch screen is not fully functional and can't move on 180 degree. its functions are much harder than other cameras. Sony need to improve these issues.
