  • A worthy upgrade.
    Verified BuyerReviewed by Wonton206 - February 25, 2022

    If you coming from the A7iii, I think it is an excellent upgrade. The auto focus itself is worth it. Wether if you are shooting video or stills, it just grab on the subject without fail even if you are shooting at f1.2. If you are upgrading from the a6000's it's a no brainer.

  • Great Upgrade at a great price
    Verified BuyerReviewed by rex450se - May 4, 2022

    Great upgrade from the already great A7 III. I've had the A7 III for a few years now and was looking to upgrade. The A7 series of camera's has been good but the A7 III made them a great buy at that price point. The IV continues this with offering amazing features found in much more expensive cameras while keeping cost at a reasonable point. If you are a studio photographer go for the R, if you shoot video go for the S, if sports are your thing or you want the best of the best, you can go with the A9 II or A1. But if you need a great all around performer that may not be the absolute best at anything but very good at everything, this is the one to get.

  • A7iv is the best hybrid in the game!
    Verified BuyerReviewed by Anonymous reviewer - January 17, 2022

    Sony really stepped up their game on this one! The flip out screen and video quality is an amazing plus. This is definitely a must have for hybrid videographers and photographers.

  • Near Perfect Camera
    Verified BuyerReviewed by DCBYCA - December 25, 2021

    This camera has so many great features and updates to the Sony ecosystem that there is very little to actually want this to also have as a feature. It’s a perfect hybrid camera especially something that’s not super focused in a particular niche. I’ve upgraded from the A7RM3 And a lot of the things that I wish would be an improvement this camera has. Amazing auto focus, great resolution, and awesome video features. I was originally a Canon shooter and this new upgrade further solidified my investment in the brand with Sony and I am glad of the choice that I have chosen.
