The A7R III is so good, so powerful and so versatile. Its troubling body-lens size mismatch, and 530/650-shot battery life, which is good for mirrorless but poor next to a pro DSLR, means it just loses half a star from an otherwise perfect score.
Superb resolution; 10fps continuous shooting; 4K video options
Body/lens size mismatch; Pro lenses are expensive; Battery life still not at DSLR level
