TTArtisan 21mm f/1.5 21mm
The f/1.5 maximum aperture and 13-element optical design deliver strong low-light performance and smooth bokeh from the 10-blade diaphragm in a compact 412g all-metal body. Full-frame Sony E-mount coverage, precise manual focus, and a 21mm focal length offer distinctive architectural and landscape perspectives without the bulk. This lens suits portrait photographers wanting wide-angle environmental shots with subject isolation, though its manual focus and 0.7m minimum focus distance limit spontaneous travel and close-up work.
