Leica 11734
Its f/1.4 aperture and 11-blade diaphragm produce smooth bokeh, while a 0.4m close-focus distance expands framing versatility, all maintained by a 9-element, 5-group optical formula with an aspherical element. The integrated round lens hood and robust, compact build weighing 338g enhance everyday handling, and the newly engineered double cam unit enables precise rangefinder focusing down to 0.7m. This lens is ideal for portrait and street photographers using Leica M-mount cameras who demand tack-sharp rendering in low light and need a wide-angle prime that can get close.
