Panasonic G 25mm f/1.7 ASPH. 25mm
The f/1.7 maximum aperture and 50mm equivalent focal length deliver shallow depth of field and solid low-light performance in a 125g body. Its stepping AF motor enables quiet, smooth focusing for video, while the 46mm filter thread keeps accessory costs low. This lens suits Micro Four Thirds shooters focused on portraits and street photography who want a fast normal prime without the bulk.
