GearScore™ Verdict — Which should you buy?
Street & Travel — X-E3 (2017): The X-E3 is the lightest Fujifilm interchangeable-lens camera with the 24.3MP X-Trans III sensor. Its slim, compact body appeals to street photographers who find the X-T line too bulky. The touchscreen joystick and Bluetooth connection are welcome additions. 4K is technically available but limited to 15fps — this is a stills-first camera. An excellent compact travel camera at used-market prices.
Professional Video & Low-Light Filmmaking — A7S III (2020): If video is your primary discipline, the A7S III is the camera. 4K/120p at 10-bit in a weather-sealed body with a 9.44M dot EVF is an extraordinary package. The 12MP sensor isn't limiting for video — and it's usable at ISO 409,600 in a pinch.
