35mm · f/2
The Yongnuo YN 35mm f/2 N offers impressive value for under $100, with decent optical performance: longitudinal chromatic aberration is slight, and lateral CA is imperceptible. However, spherical aberration causes focus shift and busy bokeh. Build quality is mixed: solid metal mount and smooth focus ring, but the barrel wobbles and feels cheap. Autofocus is quick and accurate but uses an old motor and may hunt. It suits budget-conscious photographers seeking a 35mm prime for general use, but not for demanding work.
