Battle of the 30s: Sigma 30mm f/1.4 EX vs 30mm f/1.4 ART PART2


deutsch_s1

I must confess that I like the act of taking pictures a considerable amount more than drawing comparisons afterwards. This is why so much time has passed since the last Bokeh-comparison between the ART and the EX HSM. A month later, I could finally get myself to begin searching for suitable motifs equipped with my tripod, SD1 and both 30s. As it’s all about SHARPNESS this time, “suitable motifs” refers to posters in shop windows of closed stores and wooden walls. Exactly those are the motifs making any photographer’s heart leap for joy. ;)

As was already the case with the Bokeh-comparison, I have uploaded the photos in full resolution. Just click on them to view the 15MP JPGs on Flickr. First the wooden wall photos:

When I compared the Bokeh of both 30s, I could only detect that at times the EX HSM (up until f/2.8) and at times the ART (starting at f/2.8) were alternately slightly in the lead. There is no definite winner. With regard to sharpness, things look a whole lot differently.

The ART has better resolution in the middle of the picture as well as in the corners than the EX HSM. Between f/5.6 and f/11 the margins and corners of the ART are so fine that you could even use it in landscape photography without hesitation.

  2. Very informative , well done part I and part II. I bought the “old” model with the “new” cosmetics autumn 2012 . I find it great for close portraits but not sharp enough , and to much barelldistorsion for landscape. Makes visible horizon difficult to get straight, limits the height from from ground. So I wonder if the “Art” vers. is less critical in that respect ?
