Excellent review as always Nasim!
How do you take such beautiful pictures? I love the image of the bridge, the bench and the image at the museum is also phenomenal!
Thank you for your feedback John! The bridge image is taken in San Francisco at sunrise. Unfortunately, I did not have any filters with me to blur the water more, so I had to increase my f/stop. If I had an ND filter with me or if the water was a little more wavy, I would have gotten a better shot for sure…
Hi, i bought it too.. can u give us pictures that show a field curvature please? thank u
Let me see if I can find a way to actually show this in some images. I will take a look at chart photos and then some shots at infinity later tonight. As for field curvature, take a look at this article.
Thank u so much Nasim
Gabriel, I apologize that it took me so long to get back to you – been busy with other reviews this past week. I updated the page 3 of this review with examples that clearly show field curvature issues from the center, mid-frame and corners of the frame. I hope that you will find this detailed study helpful. I also attached a visual graph that represents field curvature @ f/2.8, which clearly shows the “cone-shaped” form of curvature, using 144 areas of an image. Took me forever to run that one, but I think it looks pretty good :)
Thank you very much for the new graphics, I find it very difficult to understand if my goal is affected by forward or backward field curvature. seems to be ok close, and a little ‘less far .. but maybe I’m wrong to do the test. thanks again
Just couse i want to learn how and what shot to see clear field curvature..
Nasim, great review there!
Not quite sure about the optical performance considering the $$/value ratio! Almost sounds like, even with its uncanny bokeh and slight front/back focus throw of Sigma 35 f/1.4 – it’s possibly the best value for money overall.
Yup, the Sigma 35mm f/1.4 is a much better value for sure, which is why I gave this lens a “3″ for value.
Hello, I was always curious about a good review from this lens, and finally I found it. Thanks a lot Nasim. Br
Wow, wasn’t expecting it to look worse than competitors in the bokeh comparison! I’m not a bokeh nut by any stretch, but having halos around out of focus circles is very distracting in actual photos.
On the field I find it not suitable for portraits, it’s too sharp, and the focus is very difficult, almost impossible not to make mistakes at f1.4. You have to use the preview button. I have to install a katzeye and a magnifying eyepiece, but it does not change much, it is a design flaw of optics suffering from LOCA. It ‘a pity
I would like to see a 35mm f/2D review, please!!!! It’s the most affordable 35mm prime , since not all readers can afford a 1.4 lens!!
