Brightin Star AF 50mm f/1.8 50mm
Its manual focus-only design, weather-sealed build, and two ED elements deliver an equivalent 75mm field of view with a bright f/1.8 aperture and smooth bokeh from the 10-blade diaphragm. Weighing just 227g with a 38cm close focus, it’s a highly portable lens for detail-driven work. This lens is best for Sony APS-C shooters wanting an affordable manual focus 50mm for deliberate portrait and still-life photography.
