Canon RF 16mm f/2.8 STM
The RF 16mm f/2.8 STM is a beginner-tier (66) full-frame RF ultra-wide prime, a tiny 165g lens with a 43mm filter thread. As the cheapest full-frame ultra-wide on RF, it's a natural for vlogging, real estate, and dipping into astro. It has no image stabilization, so on non-IBIS bodies it's a weaker choice for stabilization-dependent handheld video.
