In Nikon's technical guide for the D800e, Nikon lists recommended lenses (reproduced in Michael's article, "Nikon D800 or D800e. Which to Choose?"). There is no 50mm lens listed. The recommended 85mm and 35mm lenses are several times more expensive than Nikon's 50mm which implies their 50mm lenses are not of a similar quality to the 35mm and 85mm ones.
Any recommendations for an equivalent quality 50mm lens?
