D3s and Sigma 35mm f/1.4

Very nice photographs!    However, I cannot say that this new Sigma 35 f1.4 lens is rendering the photos superior to other 35mm lenses; i.e., Nikon 35 f1.8G, 35 f2D, etc., that I have used on my D7000.    The photos are reasonably, but not exceptionally, sharp; and the contrast and color rendition are just OK, but nothing stunning.    I think that my Nikon 35 f2D has significantly better contrast and a richer color rendition.    And the 35F2D also may be a bit sharper (at least stopped down a little).    Overall, the new Sigma 35mm lens appears to be a competent but rather unexciting lens to my eyes.    Just my opinion, of course; others may well differ.
