![]() Both lenses were wide open and the Sigma outperformed the Canon in sharpness even open further to f/1.4 over the Canon's f/2. Just like in studio, there isn't really anything wrong with the results from the Canon, the Sigma is just better. here is a 100% crop of the top of the bridge, Sigma first and Canon second. That aside, let's look strictly at performance. IS is cool, but I can see the extra stop being a lot more useful in varying situations. ![]() If you forced me to pick, I would rather have the extra stop. On a tripod, the extra stop and the IS basically cancelled each other out, so from a still shooter's standpoint, they functioned about the same. I really enjoyed having that extra stop available to me when shooting with the Sigma, but the image stabilization on the Canon made a real difference when I was trying to get a sharp image. Both handled shooting at night really well, and both had their advantages. ![]() Pretty close right? At least when they aren't at 100% they are. To do this, let's look at some night shots, first the Sigma and then the Canon f/2: They are both very similarly priced and thus should be compared to each other to really select where your hard earned dollars should go. I want to just compare the Sigma and the Canon 35mm f/2 now, because of the price points. It's close though, and you really have to be scrutinizing to see the difference. The Sigma and the L glass are very close, but the L glass manages to squeak by with just slightly less vignetting. There is no fringing or distortion that takes place here in any noticeable way, but you can clearly see that the most vignetting comes into play on the Canon 35mm f/2. All three are pretty much the same sharpness. I think what we are going to glean the most out of this test is vignetting. Let's line them up one by one in the same order: Fist the Canon L, next the Sigma, and finally the Canon f/2: Let's move on to a real world example: daytime landscape shooting. Though the chroma fringing is less visible on the Canon f/2, it's just not as sharp and I'm not willing to trade those features. It's greatly outperforming the Canon f/2 in sharpness and beating the L glass in controlling chromatic aberration. Ok so we've scrutinized these three pretty harshly in the studio, and I'm willing to give it to the Sigma by just a hair. It is by no means blurry, it just doesn't compare with the eyeball-cutting sharpness you see in the first two lenses. You will also see that it is significantly less sharp than the Sigma or the Canon L glass. It's got clean focus lines, but of course we do notice the one stop difference in the lighting. You'll notice there is probably the least chromatic aberration present here of all three. Finally, let's look at the Canon 35mm f/2: If you made me pick, I would go with the Sigma being just a hair sharper. From my naked eye, I would say they are about the same sharpness. Take a look at the very top of the crop there is basically no fringing at all, which is different than what we saw on the Canon L glass. I'm going to go with it's got less fringing. On the Sigma there is either a lot less fringing or it just blends better because it's green rather than the Canon L's purple. You will notice that, aside from some purple fringing where the white script meets the black background, the image has nice defined focused lines and crisp details. ![]() Therefore, the image below was shot at f/1.4: I chose to shoot the same subject at the widest possible aperture with all three lenses. But let's get started and take a look at how all three performed in studio.įirst up is the Canon 35mm f/1.4 L. In everyday situations, it did just fine. I'll agree, some of the chromatic aberration coming out of the Canon f/2 is pretty significant, but outside of my white shooting box things weren't so noticeable. That's right, they're all pretty darn good. I shot in studio, during the day and at night to try and select my favorite of these three great lenses. Below are the prices (not sale prices) that you can expect: Before we go into the performance, let's look at price point and keep that in mind while we compare results.
