Yongnuo 35mm f2: Yongno or Yongyes?
The Yongnuo 35mm f2 lens retails new for around $100 and sells used for a few Hamiltons less. This lens is roughly 1/4th the cost of the Nikon version, but better image quality can certainly be expected from the Nikon. While the build quality on this Yongnuo is actually quite nice, the build suffers from a cheap lens cap and focus ring. The cap is never easy to fully install, and the focus ring, while well-damped, feels like it might break if you push it too far or fast. Though, at least the lens cap is an easy replacement. Moving on, bokeh wide open is decent, if not distracting. Disappointingly, the main faults of this lens are that it isn’t super sharp or contrasty. This lens is fine for most purposes, but it is not for users who demand excellent image quality. The saving grace of this lens is its auto-focus, which is a dream to use, being near-silent and incredibly agile. (Bravo, Yongnuo!) To conclude, the Yongnuo 35mm f2 is a high-value, lightweight lens with decent build quality and absolutely incredible auto-focus, but more discerning users might be disappointed with the sharpness and contrast. Crop-sensor camera users should probably skip this and check out the 35mm 1.8G DX, which brings much better quality and a slightly increased maximum aperture for around $100 more.
