Sony Alpha a7R III

Phenomenal image quality in almost any situation ; Extremely fast and responsive ; Compact, lightweight design with well-placed controls ; Superb electronic viewfinder ; In-body image stabilisation gives sharper images with any lens

AF area is invisible when moved using the joystick ; Rear screen only tilts up or down ; Handgrip too close to the lens for shooting with gloves

Fast burst mode and autofocus ; Superb all-round video and still quality ; Lengthy battery life

Large body by CSC standards ; Screen tilts but doesn’t flip

A true imaging powerhouse, with the price tag to match

Superb image quality ; Excellent low light capabilities ; Compact given its specs

Video record button is annoyingly placed ; We can’t afford one

A no-compromise compact system camera for well-heeled enthusiasts
