Sigma 50mm f/1.4 ART Lens
I am very impressed with the Sigma 50mm ART f/1.4 lens. It is a good balance between a very low priced 50mm lens and a very high priced pro level lens. In fact, for the price, this would be one of the best choices for pro level work at almost half the price. I give it a big thumbs up and I am putting it on my recommended list.
