DPReview has published their full in-depth review for the Sony a7 III mirrorless camera – The Sony a7 III achieved an impressive 89% overall score (the same score as Nikon D850, Sony a9, Nikon D5 and Canon 1DX Mark II) and Gold Award from the experts at DPReview.
Conclusion from DPReview:
The Sony a7 III is a well-priced, well-rounded camera suitable for all kinds of photography. Twenty-four megapixels of resolution is more than sufficient for most tasks, and the 693-point autofocus system and 10 frames-per-second burst speed help the a7 III keep up with fast action. Video quality and feature set is another strong point, though some operational lag, a slightly low-resolution viewfinder and unintuitive video autofocus may turn off some users.
