TTArtisan C2520BZ
With a bright f/2 aperture and a 7-blade diaphragm, this 25mm manual-focus lens (37.5mm equivalent) offers pronounced bokeh and strong low-light performance for Micro Four Thirds. Its compact 315g metal build and seven-element optical formula deliver edge-to-edge sharpness even at f/2, with a damped focus ring for precise manual adjustments. The lens is ideal for street photographers and MFT users on a budget who enjoy creative manual focus and shallow depth-of-field without the need for autofocus.
