Yongnuo YN 17mm f/1.7M 17mm
Featuring an f/1.7 maximum aperture, STM stepping motor, and just 179g, this 17mm Micro Four Thirds lens excels at low-light shooting and smooth video autofocus. Its optical design incorporates two LD and two aspherical elements, reducing aberration and distortion, while the 7-blade diaphragm renders smooth out-of-focus areas. It is best for street and portrait photographers who need a compact, fast 34mm-equivalent prime with a close focus of 7.1 inches and 1:6.67 magnification for detailed shots.
