Nikon Nikkor 50mm f/1.2 AI-S Review

---

Introduction

The Nikkor 50mm f/1.2 AI-S is the fastest lens in Nikon's lens lineup. This is one of three commercially made normal lenses that Nikon has made for the F mount that has a max aperture of f/1.2. The two others being Nikkor 55mm f/1.2 and the Noct-Nikkor 58mm f/1.2. The Nikkor 50mm f/1.2 AI-S is the only one that's still in production. With it's very wide f/1.2 aperture very shallow Depth Of Field is possible.

* with the HS-12 on the D3 it causes more light fall-off then without it.(see sample images at the bottom of the page)

Positives

• Build quality. Good old Nikkor quality, built to last.
• Very shallow DOF(Depth of Field)@ f/1.2
• Performance, good contrast/sharpness. Very usable on f/1.2
• DOF/IR markings
• Speed, excellent for low light shooting.

Drawbacks

• CA, worst wide open, but it can still be seen until f/2, however it does perform better against CA then the Noct-Nikkor.
• Hard to focus without a split prism. @ 0.5m there is less then 6mm that's in focus, so focusing correctly is crucial.
• Hood, the HS-12 causes the lens to have more light fall-off(vignetting). Not a problem on a 1.5x camera though.

Verdict

A close to perfect lens, it's a shame that Nikon still has not upgraded this lens to auto focus. When focused correctly the lens can produce stunning results wide open. The contrast is really nice for a fast lens like this as well. On a camera like the D3 this lens does show a bit of light fall-off (vignetting) which is expected for a lens with a wide aperture like f/1.2. There is increased light fall-off when used with the HS-12 hood on the Nikon D3, not sure of the reason for this as the HS-12 was designed for the Nikkor 50mm f/1.2. If only Nikon would make a split image prism for the D3, it would be a killer combination.
Compared to the Nikkor-S 55mm f/1.2, I find the bokeh on the 55mm slightly better, but the 50mm is a tad sharper. Both lenses are capable of stunning results when used properly.

A quick tip on better accuracy with MF lenses on digital bodies: If you focus past the focus indicator and then start focusing back to you see the correct focus indicator, you are more likely to hit the correct focus.
