Tamron 11-20mm f/2.8 Di III-A RXD (APS-C)

A constant f/2.8 ultra-wide for APS-C, light at 335g with a 67mm thread, this is a strong enthusiast-tier pick that ships in Sony E, Fuji X and Canon RF-S mounts. It's ideal for vlogging and landscape kits that want bright wide coverage. Full-frame shooters get only crop mode, and with no VC, handheld video leans entirely on body stabilization.
