Sony’s a7R IV arrived in September last year, offering incremental improvements over the a7R III, but possibly quite a big step up from the a7 III. In this video, photographer Julia Trotti did some tests to try and find out where you’ll feel the difference when shooting stills.
As if Sony’s naming system wasn’t confusing enough, next month could see the release of the long-awaited and much-delayed a7S III or the a7 IV — and in theory, possibly both. As it stands, the obvious comparison between what are probably Sony’s two most popular cameras is the a7R IV and the a7 III. The a7 III is still the mainstay of numerous professionals and enthusiasts alike, and many professionals are not feeling the urge to bump themselves from the 24 megapixels of the a7 III to the 61 megapixels of the a7R IV, despite the other improvements that the more expensive body offers.
Trotti’s tests are centered around general autofocus performance and image quality, but it’s worth noting that many of the differences between the cameras can be found elsewhere. The a7R IV features real-time autofocus tracking and offers Eye AF when shooting video. The a7R IV also includes a noticeably better EVF and LCD. Budget-conscious owners of the a7 III such as myself don’t mind the corners that Sony cut on the EVF, but we probably don’t want to look through the viewfinders of many cameras that have been released since it was launched in April 2018.
If you’ve shot on both cameras, what other factors differentiate them from one another? Leave your thoughts in the comments below.
