FS Review: Sigma's New 35mm f/1.4 is Amazing

Fewer things get me as excited and enthusiastic about gear in my studio than something reliable. I just want it to work. Part of the reason I haven’t shot much on a Nikon is that it takes too much thinking for me. Having shot on Canon for 10 years, I just like using something that my hands just understand. The same goes for tripods, lights, and most definitely applies to lenses. For me, the Sigma 35mm f/1.4 lens just works, and might be have the best combination of speed and sharpness in and auto focus-enabled lens I have ever had the pleasure of shooting.

When the lens arrives and even before you pull it out of the box, you will immediately be struck by the weight. This lens has surprising mass. That’s a beautiful thing, because it verifies the material Sigma has been putting out: this lens has 13 elements. That’s a lot, and you will feel the in there. Once you open the box, it only gets better.

And yes: I did mount it on the EOS M. And it's awesome. Moving on...

For a 35mm, you might expect this lens to be half the size this Sigma ends up being. It’s about half a foot long and feels like holding a new-age Zeiss or Schneider lens. You don’t cradle this lens. You heft it. If there is one thing none of us will argue over, it is that this lens looks spectacular. Brushed aluminum, glass and rubber all blend together gorgeously. The attention to detail on this lens is downright absurd. It is painstakingly built from the mount to the front element. Simple things like the look and function of the lens cap or the feel of the focusing ring… things that we don’t even think or have put no emphasis on have been brought to a different level. For example, the lens hood snaps on with a satisfyingly terse and rugged click. That’s the only way I can describe it in words, but I can promise that the way the hood snaps onto the front of this lens compared to the way other lenses do it would be similar to comparing sitting in a stadium chair at a little league game against relaxing in a truly comfortable leather couch in a mahogany scented library. Everything about this lens feels like that, making for a grand experience.

After you get past how strikingly gorgeous this lens appears and finally attach it to your camera body, things only get better. On a 5D MKIII, this lens just feels right. If it were up to me, I would have two 5D bodies and never take this 35mm off one of them. It just feels… good. Right. Like this lens was supposed to be there all along.

The auto focus is extremely responsive in all manner of light conditions. I tested this lens outdoors and in studio, in the dark and in bright daylight. In no situation did I ever feel like the lens didn’t keep up. As with the other new lenses Sigma has put out in the last six months, the focus is snappy, accurate, smooth and totally silent. Bravo to the new AF motor.


Let’s talk about sharpness. My goodness is this lens ridiculously sharp. Remember my review of the Voigtlander 40mm pancake and how I said it was the sharpest lens I ever had the pleasure of shooting? Well it’s been replaced. This Sigma is sharper, and remains so even at wider apertures than the Voigtlander could go. Though it only stops down as far as f/16, I don’t see you ever needing or wanting to go any lower with this lens. The whole point of this lens is to be wide open and tack sharp in a very focused area. In that task, this lens performs magically. As I write this, my heart is clenching up like I’m sitting across from the woman I love and trying to describe the bliss. It’s that kind of feeling. Extreme? Maybe. But you can’t judge me until you’ve shot with this lens.

That photo of the flower? Yes. The stamen is in focus. And I know that this isn't really a portrait lens; the distortion can be really severe. However, I was really happy with the studio results and they really show off what the lens can do.

As with nearly any lens, the Sigma is not perfect (though it is one of the few that comes really close). In certain situations, I did notice some flaring and chromatic aberration issues. The images below were taken on the EOS M and the eye was taken on the 5D MKIII. Though you can’t deny that the Sigma is far sharper than the 22mm lens included with the M, you will notice the flaring and chromatic aberration around the silver lettering: Sigma right, Canon left. The Canon isn't completely innocent here either, note. You can also pick out some greening on the edges of the image of the eyelashes, but only if you're really zoomed in. Like I said, it's minor, but it's there.


The Sigma also has very minor vignetting at f/1.4 that diminishes entirely by f/2.0. When I say minor, I mean really minor. I only noticed it on the full frame camera (though admittedly this is the only camera where I was hoping to see none), but it is an extremely minor vignette that just barely shades in the corners of the frame. When shooting on an APS-C, you don’t have to worry.

For those of you who shoot video and are considering this lens, be aware that there is no optical stabilization. This was not built for video. This is a still-shooter’s lens. That’s not to say it doesn’t shoot glorious video, but do keep in mind that as far as options go, it’s probably not the one you should reach for first if all you plan to shoot is video. It does low light video amazingly well because of the low aperture, but you're going to have to tripod this lens all the time if you plan to get anything usable out of the footage.

So let’s look at this lens from a truly pragmatic point of view. It’s uncannily sharp. It’s ridiculously beautiful. Yes, it has some chromatic aberration and vignette issues, but hold your horses: This lens is only $900. $900, ultra sharp and fast with only two minor complaints? Hard to argue with that.

Sigma kept their promise of delivering quality without compromising the pricing we have all come to expect from Sigma over the years: it’s cheap at only $900. It is far and away the cheapest auto focus enabled 35mm f/1.4 lens available. It blows Nikon and Canon out of the water in terms of price, and I have a hard time believing either Nikon or Canon can beat this Sigma in performance. It’s entirely likely they can match the Sigma on performance, but if that’s the case, why do I need to pay such a premium for them? Fact is, I don’t. And that’s the beauty of this lens.

What I liked:
Look and Feel
Silent and Accurate Autofocus Motor
Lens Speed vs Performance

What Could be Improved:
Some issues with chromatic aberration
Extremely minor vignetting wide open, but dissolves at f/2.0

For a few months now I have been talking about Sigma upping their game. That has been met with mixed opinion from you readers, but the general consensus is that we all want Sigma to succeed. We desperately want another option in the market that we can go to for quality and price instead of being forced into the pricing of Canon or Nikon. If Sigma continues to perform at this level we will have our wish.


If you are considering the 35mm lens, I can’t recommend Sigma’s enough. For those of you looking on warily from a distance, I urge you to give this guy a shot. Rent it for a few days to test it out. If you’ve had a bad experience with a Sigma in the past (I know the feeling, it's happened to me too), give them one more chance to win you back. After shooting with this lens, I firmly believe they won’t let you down again.

a comparison of the sigma vs the new canon 35 f2 would be very interesting! i can't decide which one to buy right now :(

Stay tuned...

While you're at it add some bokeh comparison shots. For most the Canon is already sharp enough, so they look at the Bokeh for comparing the lenses.

Also the CA on the lenscap is unfair, the sigma has a narrower DoF/wider aperture which causes the CA. 

Other than that this is a nice review with some real-world samples and stories instead of pixel-f-ing in a lab. Good job.

Brandon Luckain's picture

Great review. I'm sold.

Paul Monaghan's picture

For video Pentax and Sony user's could use this lens with the in build stabilisation, I don't know why more people don't incorporate this into there bodys,  Olympus's new one in the em-5 is men't to be amazing.

Looks like a great lens, I love the new look.

After having struggled with Nikon's repair costs and AF fine tune issues, one thing that excited me about Sigma's new lenses is the ability to fine tune the AF yourself; does this lens have that ability? I believe Sigma said they are going to include a USB port to connect to your PC for this.

Jaron Schneider's picture

Yes, this lens does accept that fine tuning, but it's a separate purchase for the device that does it. I have not tested that device.

You mention some minor CA wide open, can you compare it to either the Canon or Nikon versions? I tested a Canon 35 f/1.4 yesterday on a 5Dmk3, this probably isn't the best test of the lens at all, but I was surprised at the amount of CA. The shop I was in didn't have the Sigma 35 in stock yet, but if weather sealing is the only standout benefit of the Canon...I'm really leaning towards the Sigma

A couple others with far less CA:

Richie Velasquez's picture

Hi Zach. I own the Canon 35 1.4, and it does not have weather sealing. It is, however, one of my favorites. I've yet to see a Sigma out do an L lens, but I'm def open to try this guy out. Cheers.

Zack Williamson's picture

Oh that's my mistake then, not sure why I thought it did...maybe thinking of the 16-35. Well that pretty much seals the deal for me then.

Anders Petersen's picture

I - too - would like to see a comparison of CA. And more importantly: LoCA.

Back- or sidelit specular highlights both in front of and behind the focal plane.
If it's better than the Canon 35/1.4, I can not see any reason why anyone would ever want the Canon over the Sigma. I'm still trying to figure out what the catch is on this lens, because there's got to be <i>one</i> downside... Right? AF accuracy maybe? Front element falls out? Asbestos?

Considering selling my 16-35 2.8 for this, I do love that wide 16mm though...

Richie Velasquez's picture

I'm looking to buy that 16-35 :)

Stephen J Cameron's picture

You described it as the "Sharpest autofocus lens" that you have ever used. 

I am not sure if you used the Nikon 85 1.4G or not, Would you rank the Sigma 35 1.4 higher than the Nikon 85 1.4G on terms of sharpness wide open? 

Jaron Schneider's picture

Yeah sorry... Don't shoot Nikon. If it is like the Canon 85mm, these are pretty darn close in terms of sharpness. It's the overall package that takes the Sigma above and beyond for me. However, you really should own both lenses, as they are for two totally different situations. 

Cosoo Reds's picture

Great review, thank you very much!
What about the bokeh of this Sigma ? 

I am still hesitating with the 35mm Zeiss Distagon f/2 but don't know yet if the Sigma @ f/2 is sharper than the Zeiss @ f/2. A good comparison of those two would be great since they are "almost" the same price range (at least cheaper than the Canon's or Nikon's).

Last question, are we going to have the same quality than the tested lenses in our store ?

I really wish Sigma would publish a roadmap of which lenses they plan to bring into their new lens line and when. I know it would risk reducing sales of the current, lower quality, line but it also might make me wait on a few other lenses I am planning on buying in the near future from other brands. I imagine I am not the only one in this position.

Jaron Schneider's picture

Dude, right on. I want this too. But that's really rare for a company to do because it hurts sales. From a strategic standpoint, it doesn't make a lot of sense for nearly any company. 

Ya, im wondering if they have any stats on it. Because on one hand, yes it will hurt sales, but on the other it might steal sales from other competitors. Be interesting to see if there is a net loss or gain.

This is especially interesting in this case because as potential Sigma customers we already know more lenses are coming that should be much higher quality than what they have now. Tbh I probably would hold off buying any Sigma lens at this time whethor I know what is coming or not.

John P. Argueta's picture

I have the Siggy 50, 85 1.4 &amp; 105 micro for Nikon and can say the are pretty awesome. If they decided to reintroduce them on the market though in the "A" line, I would sell them off &amp; upgrade as the new 35 feels, looks and performs awesome.

Robert Simpson's picture

I really like your review style, Jaron .... keep 'em coming! 

Jaron Schneider's picture

Thanks Robert! The goal is to give a type of review you won't find anywhere else. If you want numbers and tech specs, there are other sites who do that sort of thing. We like to review from a real-world shooter's perspective. 

comparing a $900 lens against the 22mm pancake kit lens... you'd better HOPE its sharper......

i'm a sigma fan myself, but i would barely call this the sharpest lens ever, the sigma 17-50mm f2.8 is really sharp and i liked it better than the canon 17-55mm f2.8 (ive had both), but i did have to sell that once i moved up to full frame

Sigma dug themselves a big hole, and it will take a lot to climb back out.. This seems, by all accounts so far, to be a step in the right direction..

Benjamin Lam's picture

I've been waiting for reviews for this before deciding buying this or the Canon lens. For the lower cost and quality, this is what I'm looking at now.

I also love the design since it looks so clean. I can't wait to see what Sigma has next.

Jaron Schneider's picture

I got a look at the next two lenses coming soon as well, and they're just as beautiful. Really really happy with Sigma these days. 

Anto de Chav's picture

Canon's new 35mm L will be released next year and no doubt it will be excellent.. just more expensive..

"In certain situations, I did notice some flaring and chromatic aberration issues."

I don't know of a single large aperture lens that won't have this problem wide open. Closing it one stop increases image quality dramatically. As a matter of fact, I'd like to see how the Sigma looks under light conditions like this. Here is the Samyang 35mm f/1.4 (an excellent optic, I might add) wide open and at f/2:

This image is actually a little smaller than 1:1, but you can get the idea. Similarly (and much worse, actually), here is my old 1980s 50mm f/1.4 Nikkor Ai optic:

Again, slightly smaller than 1:1, but the picture(s) say it all. Notice what a ONE stop difference on either lens does! I would very much like to see what the Sigma looks like under these conditions. I'm willing to bet it will look very similar to the Samyang.

Joe Russo's picture

Bought one yesterday for my D3S.

Very good at 1.4, even better at f/2.
I have the 35mm f/2 Nikkor, and the Sigma is about the same or sharper at f/1.4 than the f/2 is at f/2. Great stuff here.

Pretty good/fast autofocus, spot on straight out of the box. Haven't tested it a lot, so not sure if focus seeking is a problem. I'll find out this weekend in tough club/live band situations.

Build quality is amazing. But I think it's just shocking because it's a Sigma. haha

This is my first Sigma lens, and I hope it doesn't disappoint. Rented the Sigma 24-70 before and it was a huge disappointment.
