Sigma 24/1.4 or Sigma 35/1.4 for reportage photography & people

Hi,

I'm looking for a new lens for my Canon 6D.

I need a lense under 50mm.

So, I like pictures with wide angle and a big aperture. I think this job could do the Sigma 24/1.4 ART or Sigma 35/1.4 ART very good.

I’m not sure, if faces with the Sigma 24/1.4 stretch too long, when I take a picture of my family in front of a lake or something else.

What do you think?

My approach is a bit off-kilter. I would go for the Σ24mm f/1.4A. It has no reasonably priced competition. You can save a lot of money by getting the EF 35mm f/2 IS USM instead of the Σ35mm f/1.4A. It ain't f/1.4, but it ain't $900 either.

The 35/2.0 IS is very nice. But I like to have a lens, where you can't get at a APS-C sensor.

I don't understand what "cant' get at an APS-C sensor" means. Both Sigmas and the 35 IS work on full frame and apsc.

I mean, you can't achieve the same bokeh.

Background blur is affected by focal length, distance from camera to subject, distance from subject to background, and aperture. Sensor size is totally irrelevant to amount or quality of background blur.

I know. But I can't buy a 16mm f/0.4 for a APS-C camera. This is my point.

And the blur is different, when you compace a Canon EF 24mm 2.8 IS and a Sigma 24mm 1.4. This is my point.

Heya,

I'd go with a 35 F1.4 here. Wide, but not so wide that you have to be in someone's face. Still plenty of environmental room with the width.

But the difference between 24mm and 35mm is pretty significant. If you don't know which you will want, I suggest you rent a zoom with 24mm and 35mm on it, and see which field of view you prefer and that should help you figure out what lens to get.

Sigma 35 F1.4 would be the one to get.
Canon 35 F2 IS if you want IS for slower shutter speed options.

Very best,

Do you have a lens that covers 24, and 35? Set it at those lengths and see which one works for you...there is also the 24-35 f2, although it might not be fast enough

I favour the 35mm focal length for these purposes, so that'd be my choice. That being said, though, in cramped spaces where you want/need to include more the 24mm is a better option.

Also, people will be less distorted @ 35mm.

Yes, I'm afraid, that all portraits with the 24/1.4 will be distorted.

Not really or necessarily: http://www.diamantstud​ios.ca/portfolio/portr​aiture/

If you focus on the photos in the two bottommost rows (starting with the woman and the cat, which will be #1), all those were taken with wide angles (primes). #'s 1, 5 and 6 were taken with a Zeiss 35mm f/2; all the others were taken with a Canon 24mm TS-E.

As long as you keep your subjects away from the edges, the distortion, if any, will be minimal. (If you look at photo #3, you can see the body of the woman on the right looking somewhat enlarged (although her face is fine): she was past the wide angle's 'portraiture sweet spot'.)

For me, 35 mm is plenty wide for photos of people. I wouldn't want to go shorter, but some obviously do. I am referring to use on full frame. It all depends on the sorts of photos you want to get.

Ummm sensor size is one of the factors, it's probably not nearly as important as the others but it's still there.
