Naturally many potential buyers will also be comparing the lens to Sigma's 50mm F1.4 EX DG HSM, and the choice between the two is far from straightforward. Both lenses are excellent, but with a different balance of strengths and weaknesses. In many regards, the answer therefore comes down to what format and application you're thinking of using the lens for. The Sigma performs a bit better at the largest apertures - it's sharper, especially in the middle of the frame, and the bokeh is more attractive - which makes it more appealing to users looking to use a fast 50mm as a short portrait lens on DX. But for anyone looking for the best possible image quality across the whole range of apertures, especially on FX, the Nikon is a hugely attractive option. Corner sharpness becomes distinctly better at apertures smaller than F2.8, and chromatic aberrations are lower; and at its sweet spot of F5.6 to F8, it's simply superb. It's also worth bearing in mind that the Nikon is considerably smaller and lighter than the Sigma, making it a more discrete and portable solution.
Essentially, with this lens Nikon has produced perhaps the best-balanced full-frame fast 50mm autofocus prime we've yet seen. It may not be quite match the sharpness and clarity of the Sigma at F1.4, but it's still perfectly usable wide open, and once stopped down to F2.8 it's more than a match for anything else in its class. When used on the D3X in particular, it produces some of the most detailed, aberration-free images we've yet seen, and our test results suggest there's still plenty to spare for even higher resolution sensors. It's very good on DX too, and an attractive option as a short portrait lens. This all comes in a relatively small, lightweight package, at a price which, while higher than the older 50mm F1.4D, won't break the bank. All in all it's an excellent replacement for what was already a very good lens.
