Sigma 50mm f/1.4 DG DN Art
The Sigma 50mm f/1.4 DG DN Art brings Art-line fast-fifty rendering for hundreds less than first-party f/1.4 options, with HLA linear-motor autofocus quick enough for video — a strong enthusiast standard prime. At 660 g with a 72mm thread it earns its place in the kit. It's for Sony E and L-mount shooters wanting that bright, characterful look; travel-light kits may balk at the weight, and it isn't offered in other mounts.
