with a Nikon D3 housing since 2008 and working for different zooms with, I wanted to find the natural distortion-free brings the 50mm. I bought this lens f: 1.4 to plastic structure manufactured at low cost in China, saying that I will opt later for a 50mm opening to better manufacture 1.2. I returned from Africa with a package of photos, comparing various objectives which this AF-S 50mm / f: 1.4: an exceptional dive, very bright, brief aside a tune lymphatic mark (but nothing prevents to do in manual!) nothing but good. To go further in the comparison, stubborn as I am, I wanted to acquire the Nikkor Ai-S 50mm / f: 1.2 manual of legend. I worked in comparative endless hard to try to prove its superiority, but nay! Apart from a better diaph and pretty retro look, nothing helped: he was crushed by the AF-S Nikkor 50mm / f: 1.4G !!! Then you know what you have to do ... and don'ts.
