Nikon AF-S Nikkor 50mm f/1.4G
This sharp 50mm isn't quite a match for the best of its competitors 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 full-frame, 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.
Everyday photography on full-frame and portrait work on APS-C, where its excellent sharpness and refined handling are very useful.
Shooting fast-moving subjects, where the AF-S focus might not be quick enough, and shooting into the sun, where (as usual with lenses of this type) flare can be an issue.
Review of Nikon 50mm f/1.4G AF-S Nikkor
By: SLR Gear
The Nikon 50mm /1.4G AF-S tested well in our labs, marred only by soft results with significant corner shading when set to its widest aperture. Set to /2 it makes a nice portrait lens - sharp center, soft corners - and by /2.8 it's a decently sharp lens across the image. We were a bit surprised by the slower performance for autofocus, leading us to wonder what target audience Nikon is aiming...
