I was a D800 user and have used a lot of the 50mm lenses (1.4D, 1.8D, 1.8G, 1.4G 1.2AIS). The Canon 50mm 1.2 (and similarly, the Nikkor 50mm 1.2 AIS) is not as sharp as the Sigma especially outside the center and it has less contrast that's why their bokeh might seem a bit creamier. ![]() It's also less sharp but has great character. The Nikkor 58mm can certainly create creamier bokeh since it's a bit longer. The thing about the Sigma 50mm Art is it has more contrast compared to the Canon 50mm 1.2 and Nikkor 58mm 1.4. The 50mm definitely produces better bokeh.Īnd about Kai's thoughts, he was comparing it with the Canon 50mm and Nikkor 58mm. I disagree with the comment about the bokeh of the 35mm is better than the 50mm. I'll vote for the 50mm Art if I have to choose between the two. I do this to get a sense of a lens's 'signature' which, while certainly not definitive, has helped make these lens choices. ![]() For further assistance I highly recommend poring over various lenses you're interested in and gazing at the myriad samples listed by specific groups on Flickr. I've concluded that of the two optics and the FOV comment not withstanding which I totally concur, the 35 Art may be the better of the two. My feeling about the 50 Art is that it might be TOO sharp and may explain it's less satisfactory bokeh, while not too shabby, for me. (For example with a subject 4 feet away having a background depth of at least 28 feet should produce some magical results.) This, of course, is not absolute but what I've found to be a good rule of thumb. My trick is shooting wide open with my subject height filling the horizontal viewfinder and trying to make sure the background distance is 7x to 10x the subject distance to insure the magic. It is extraordinarily smooth and soft for any lens let alone a wide angle 35mm one. I can only say from the images I've seen with my 35 Art the bokeh produced by this lens under the right conditions rivals a Noctilux. ![]() I think it has something to do with diffraction and it's something you would notice with your nose touching the print. It's essentially a faint double edge in the out of focus areas at certain distances and apertures. The double image stuff is something that I've noticed with all lenses.
