Best Mirrorless Camera

Best overall

Sony a7 III

The Sony a7 III may fall into the “basic” category, but in actuality, it is an extremely capable full frame mirrorless camera. It is a versatile camera which is suitable for all types of photographers and photography.

The viewfinder is a 3-inch touchscreen which has a 921,600 dot resolution and can be tilted for your convenience and for taking pictures from difficult angles. The XGA OLED monitor of the camera has an astonishing 2,359,296 dots.

The front and rear dials are easy to access and use. Also, the camera has two SD card slots, one of which is UHS-II rated for high-speed transfers.

The auto ISO implementation is another feature we love, and which will eliminate one exposure parameter you need to tackle and worry about when taking pictures or shooting videos.

You just need to specify the minimum and maximum ISO values, and choose the minimum shutter speed or leave it on Auto. You can also customize the buttons on the camera body to further speed up this auto process.

The shutter is silent and the camera is quite compact, depending on the lens you pick.

Overall, at this price, you cannot find a full-frame mirrorless camera with better features and quality on the market. It can be used by professionals, semi-pros as well as by your family members and friends thanks to its full auto mode.
