It seems the new Sigma Art lenses are well named as they come with art included. A fellow photographer and I were out looking at lenses and tried out the 35mm and 50mm Art lenses.
Not only are they fine lenses but, if you look at the images below you will see that the lens itself includes a piece of art. The lens coating produces a beautiful coloured display captured in these images.
The black and white portrait was shot using the 50mm Sigma Art Lens, while the shots of the 35mm Art lens were shot with the Canon 24-70 2.8 which is also a very fine lens.
