Artra Lab Lunaelumen-R 50mm f/1.1 50mm
The f/1.1 maximum aperture and 11-blade diaphragm deliver extreme shallow depth of field and smooth bokeh, aided by a Low-Reflective Multilayer Coating to reduce ghosting. Weighing just 396g with a 35cm minimum focus distance, this manual-focus prime remains portable for full-frame Canon RF shooters. Best for portrait and macro photographers who prioritize ultra-fast aperture control and deliberate manual focusing over autofocus speed.
