Comments about Sigma Sigma 50mm f/1.4 EX DG HSM Auto Focus* Lens Kit, for Maxxum & Sony Alpha Mount. (*Auto Focus only if body supports HSM) with Tiffen 77mm UV Filter, Lens Cap Leash, Professional Lens Cleaning:

I have the Nikon 50mm F1.4G, first time it was difficult to decide wich is better, buy first Nikon, then Sigma, after several shoots in field, if you focus a person, two or three in a concert, wedding, portrait, just think it´s genial, forget Nikon, and need to use this master piece every day. Perhaps in F5.6 in the square Nikon is better but in the real life, you only can find every target in focus, brilliant. Only sometimes a big group, or basket match, look a little better with NIkon, but 80% of photos you will choose Sigma, it´s very sharp with d3x or d3, and of course d2h.

This is an amazing lens. I know some people who think I was crazy for paying so much more for this Sigma than I would have for the Sony 50/1.4 but it was worth every extra cent. And I would buy it again in a heartbeat.

It's fast, super fast. It's sharp, super sharp. It's so quiet it makes my other lenses sound like power drills.

And the results, well I've never been more pleased with a lens. This should be the industry standard for a 50mm prime lens.
