82 out of 100 medium confidence 24 reviews
The Pentax HD DA 20-40mm f/2.8-4 ED Limited DC WR lens is highly praised for its superb build quality, sharpness, and beautiful color rendition. Users love it as a versatile walk-around lens for street photography and landscapes, especially on APS-C bodies like the K-3. The main drawbacks are its variable aperture and a price that many feel is too high for the performance gain over kit lenses.
