Yongnuo YN42.5mm F1.7M II 42mm
The 42.5mm focal length (85mm equivalent) and f/1.7 aperture deliver smooth bokeh and low-light capability in a tiny 146g body with STM autofocus. Its discreet, pocketable design integrates unobtrusively on small Micro Four Thirds bodies like the Panasonic G100 or Olympus E-M10 series. This lens is best for street photographers and budget-conscious portrait shooters who need a fast, lightweight prime for everyday candid work and environmental portraits.
