Brightin Star 9mm f/5.6 9mm
With a 132° field of view and near-zero distortion, this 9mm f/5.6 manual-focus prime delivers rectilinear ultrawide shots that avoid fisheye warping. Its 20cm minimum focus and 5-blade diaphragm creating 10-point starbursts make it a dual-purpose lens for both architecture close-ups and nightscapes. Best suited for landscape and architectural photographers who need true rectilinear wide angles and can work with manual focus and the 780g weight.
