Reviewer Consensus

Exceptional

The Sony a7R III is a versatile, high-resolution mirrorless camera that significantly improves upon its predecessor with faster autofocus, a larger battery, and enhanced ergonomics. While it remains a top-tier choice for professional stills and video, some users may find its complex menu system and limited touchscreen functionality a hurdle to overcome.

    While the a9 remains a better Sony option for some fast action sports and similar uses, the a7R III is my strong preference for most other uses and it is my most-recommended Sony camera model.

    Before the A7R Mark III (and D850), you had to choose between having a high-resolution camera with a maximum shooting speed of 5fps (5DS, and A7R II), or a high-speed camera with fast continuous shooting (such as the Leica SL, A9, etc), and a lower resolution of 24mp.

    The combination of 42.2MP, 10fps burst shooting and a very sophisticated AF system makes this a very attractive camera indeed: Sony has taken an already excellent mirrorless camera and made it even better.

    If you have the skill, clients, display size, display medium, viewing distances, ambition, a real but limited budget, and can live with the ergos, the Sony a7R III with its lens ecosystem is extraordinary and truly worthy.

    There's little doubt in my mind that the A7Rm3 is a great camera. Sony has improved the previous model in so many useful ways that the A7R now stands up against many DSLRs.

    Stick with lenses sold by Sony, be they branded Sony or Zeiss, for the best results as you expect. Sony's G and GM lenses are especially excellent in every way on the A7R III.

  • It's a strong option, but it isn't inexpensive. The lenses aren't inexpensive, but you do get a Ton of capability and flexibility for your money, and if that's important to you, definitely take a look at this camera.
