In pictures - Nikon's large and pricey AF-S 58mm F1.4G
The AF-S Nikkor 58mm f/1.4G: a distinctly premium lens
The 58mm F1.4 is not designed as a mass market product. It's aimed at professionals and discerning amateurs, quite likely shooting with a full frame SLR like the 36MP D800 or the new 24MP D610. Users of DX format SLRs should find it works well as short telephoto 'portrait' lens.
