That’s based on my personal experience.ĭXO testing shows the two lens are optically on par in almost every respect and that when mounted on a Canon 5D Mark IV, the 35mm f/2 IS USM is actually slightly sharper. The Canon with its IS and smaller lighter size can be more versatile particularly if you travel a lot and take primes with you. The Art is by a good margin better in terms of IQ. Nikon Z fc, Nikkor Z 16-50mm, Nikkor Z 40mm f/2, Nikkor Z 28mm f/2.8 (SE), Nikkor Z DX 18-140mm, Voigtlander 35mm f/1.2, Voigtlander 23mm f/1.2, DXO PhotoLab 5 Elite, DXO FilmPack 6 Elite, DXO ViewPoint 3 So on a full frame body, the Sigma allows in a bit less than 1 additional stop of light and on Canon crop frame bodies it lets in a bit more than 1/3 stop of extra light. Testing shows that the Sigma 35mm f/1.4 ART has a tStop of 1.5 on full frame Canon bodies and 1.7 on crop bodies, while the Canon 35mm f/2 IS USM has a tStop of 2 on all bodies.

DXO tests light transmission and utilizes a tStop value for comparisons. I am hesitant to sell my Sigma 85mm F/1.4 EX for that reason, I may not find another copy that works as well as this one.Īctually the 35 1/4 does not give you an extra stop of light. Sigma make some really great lenses and if you do sell it and decide to buy one back, you may very likely not get as good of a copy the second time. Although if you have a copy of the Art that has no issues with wide open performance and AF, I would recommend keeping it.

I love my 35 IS and if I was going to trade it for another 35mm on a Canon body, then it would be the 35L II. You'll find sharpness wide open the same but it would pretty much come down to a few specific things per lens.ģ5mm IS - Lighter, IS, better AF and slightly cheaper.ģ5mm Art - A stop extra light, less vignette wide open.
