Sigma 40mm F1.4 Art beta sample gallery

Sigma debuted a number of lenses at this year's Photokina, including two Art-series primes. We got our hands on a beta sample of the new 40mm F1.4 Art, which Sigma's CEO Kazuto Yamaki describes as a 'reference' lens for the entire Global Vision range.

Click through to our initial gallery, shot during the Photokina show in Cologne Germany to see how it performs.

Please note that the images in this gallery were shot with a pre-production Sigma 40mm F1.4 Art. Raw files were converted to JPEG via Adobe Camera Raw, at standard DPR settings. Image quality may not be totally representative of final shipping lenses, but is likely to be very close.

Looks like it's up to the usual (excellent) optical Sigma Art line standards. As I already have the 50mm Art I don't fortunately feel any temptation to get an another fast prime pretty close in focal length though.

(regarding the weight, I suppose I'm in the minority feeling pretty much indifferent about it)

Agree with all, lens is way too heavy for 40mm prime lens. 1200g or 360g 40 f2 Batis?

Agree with all?

I like the fact that it's a heavy lens, the heaviness makes it easier to handhold steadily.

milkod2001

LOL, no, you don't need lens to be heavy to make it easier to handhold.There is always weight of camera which helps doing that. Imagine you have to do wedding for whole day. Handhold this and handhold Batis. What would you pick? 1200g or 360g 40mm prime lens?

Angus Wolf

It's OK, you don't have to understand, one day you might.

My largest lens, that I handhold, is 3.27kg. I typically will shoot with it for 4-5 hours. That doesn't mean that I am constantly holding it up to my face, just like a wedding photography isn't holding their camera to their face for whole day either...

Maybe work on your technique or do some exercises, being a keyboard 'warrior' isn't going to make you any stronger. ;-)

Great solution , making lenses heavier so it will be easier (more steady) to handhold in 1% of time you will gain like 10% compared to lighter lens, genius solution actually :)

Those who say that a heavier lens helps you to shake less remind me those who say that heavier cars can run faster around the corners because the wheels have more weight pressing them down.
If it would be true we would be in candy land, as adding weight is much easier than to remove! Not even the strangest Chinese factory makes a brick with a standard 1/4" screw, and just take a brief look on what there's on aliexpress: if something can be thought, you'll find there!
Simply try to attach the tripod closed under the camera, and tell me if you get sharper results at long shutter speeds!

People who brag about the heaviness of their lenses always make me laugh. 3.27kg is literally throwaway weight compared to what I rep out in the gym (currently squatting + deadlifting about 50x that for reps) but I still don't want heavy lenses if I don't need them. Is a photo at F/1.4 really that much better than one at F/2? No. Are people putting subjects at the extreme corners of their frame wide open (or at all?)? No. Given how excellent the smaller + lighter 35 & 50 ARTs are, and the fact that 40mm is close to normal (which is the easiest FOV to make lenses for) this seems completely unnecessary. 82mm filter, 1.2kg.... no thanks.

Who was bragging? I was stating a simple fact, do you have comprehension issues? Then YOU turn around and brag about how much you can lift...LOL! That is seriously funny, thanks!

Why are you comparing a lens with weights in a gym? That's not analogous. Are you a steroid meathead? Who cares (other than you) what you can dead-lift at a gym? You actually made me laugh out loud there, thanks!

If you think lighter gear is better, get a Pentax Q series camera.

I was going to suggest that maybe one day you'll understand but I don't think that will be the case with you. Maybe stick to the gym, that's more your speed, photography seems to be beyond your grasp...

Go meathead, work on those lats bro! ;-)

Not sure I follow. You brought up your heaviest lens and suggested people complaining about this weight shoud "do some exercises". I speak to the exercises I do and you're surprised. You speak with pride of how heavy your biggest lens is, but if I bring up the weight I'm capable of lifting I'm bragging. Anyone who doesn't want a 1200g prime has to shoot Pentax Q. It must be exhausting to live in a world with such poor comprehension skills, poor memory and double standards. A 1.2kg 40mm lens is stupid. A walkaround focal length relegated to studio use by its weight and size. If not wanting that makes me a weakling so be it.

I'm going to reply though, because I can and I want to.

Again, 3.27kg is not impressive; my kid weighs over 2x that and I carry her around for hours... and I already spoke to what I do in the gym. So the notion that people who don't like heavy lenses need to "do some exercises" is almost as stupid as bragging about being able to carry 3.27kg. That's not even the weight of a gallon of milk. With current tech there is no need or justification for a 1.2kg 40mm lens.

IQ looks promising.
However, until I put my hands on that "beast" at Photokina I didn't knew that this is a 1200g lens. Speaking for myself I wouldn't consider it, because it will for sure be quite top-heavy even when a VG is attached to the A7R3. That is reason why I am going to be happy with the one stop slower Batis - it's weight is little more than a fourth of Sigma.

I am interested in this 40mm focal length and lens IQ but... with its weight/size in my Pelican case, it would be an oversized Cuckoo, dwarfing its 28mm e and 105mm e Nikkor nestmates. Beyond my size/ weight concern, I can imagine the price.

Nice and everything but at 1200g there's no chance I would ever consider it. I have Canon 40mm pancake for years and love it. It weighs 130g. OK, it's f/2.8 but that+s enough on modern cameras.

Using a 2.8 lens, with what "modern camera" do you get the same shallow DOF of a 1.4 lens ?

Strangely enough the 40mm pancake covers 645 MF, so you get about a 25mm f1.7 equivalent (if you can afford the body)!

I wish Nikon would have made one, maybe less faster, smaller, like canons EF 40mm. I would buy one in a heart beat.

sportyaccordy

Me too. I've bought 2 copies of the 40 STM, and I am saving my pennies for the Batis. 40mm is a magical FL; much more interesting and natural than 35mm... but 2.8 is just a hair too slow. Really bummed about this lens's weight

1 month ago
Sodeska

Images look fantastic, but I would never even consider a 1,2kg 40mm. The 360g Batis would have to suck bigtime for me to choose this thing over it. 40mm is perfect for walkaround, travel, reportage and «one lens to cover all»-situations. For all of these I would pick the lens that has weather sealing and weighs under a third of what this Sigma does - evey time. The extra stop of speed and light is good to have, but not worth 850 extra grams.

Dan,
What is the point of shooting a lens test on a 50mp camera at anything above 200 iso ? Many of your shots with the 5DSR at 1600 ISO and above, are so grainy that the finer nuances of the lens are lost. OK so it Germany and a bad days light ..... so take a tripod and show us what this lens can do on a high megapixel camera.

I like the look of this lens a great deal, thanks for the extensive samples. Purely out of curiosity, what are the "standard DPR settings" for ACR/Lightroom? Are these documented somewhere? Would love to try them.

Looks like an extremely high quality lens, as it should be given its massive size.

Nice photos from a lens with objectively the best focal length there is.

I could consider as a 35 f1.4 alternative as FL is not that big difference. But one thing bothers me that why Sigma Art lenses are so unnecessarily bulky, 1200 g (2.65 lb)? They have not learned how to optimize lens design in size/weight without compromising optical quality. In addition likely FE 40/1.4 Art is also not designed from scratch but adding an extension tube on DSLR design for Sony E-mount.

A good example is that Sigma 105/1.4 Art vs Nikon F-mount version that Sigma is significantly heavier/bigger but Nikon still wins in optical quality slightly.

I'm sure they could but then they'd charge Leica prices and people would complain about that. Pick your trade off

Basically 35mm and 50mm Art lenses are not meant to be replaced. They are lighter candidates meant for most users. This 40mm is targeted for those wanting no compromise on IQ at a focal range covering most needs in normal range. Especially thinking that its design is similar with that of Cine lens, it can be used also for video purposes. I hope the AF will be even more silent, because my 35mm although silent, its noise is enough to be heard through in camera microphone. I do not know if such a problem could be alleviated with an external microphone.

KristinnK

To bring down lens size without compromising resolution you have to use aspherical elements which are very expensive.

Basically Sigma looks at the 'choose two' triangle of size, sharpness and prize, and pick sharpness and prize.

To illustrate this with the example you mentioned, the Sigma 105 f1.4 costs 1600 USD vs 2200 USD for the Nikon 105mm f1.4.

Sigma is using cheaper glass types. Which means element size and count goes up to get same performance versus more exotic glass composition in other lenses. Hence how they can undercut their competitors in price.

Who told you? Matt in the video below tested side by side and found out Nikon is still better. Sigma is significantly heavier and bigger. The only advantage is $600 cheaper and available on EF and FE mount as well.

I believe the sharpness or bokeh difference between two are very small, although personally I'd trust OEM lens better in general especially on DSLR. Sigma lenses have history of compatibility and AF accuracy issue on Canon and Nikon mounts. The big difference is in significant size and weight difference. This 105 Art is even heavier than 70-200/2.8 zoom that you will feel pain to operate it in a portrait or wedding event after a while. The question is if worth for $600 cheaper for Nikon F-mount owners.

Enjoyed the sample photos, look generally good with nice, punchy colors. Would be a nice replacement for my Canon 40mm f/2.8, but unfortunately it's not that luxurious pancake-sized like the Canon.

You are completely on wrong direction comparing it with a f/2.8 lens. The two lenses have different purposes. You seem to have chosen yours.

FOV? No. For light and DOF? Yes, you are correct. And yes, I have chosen, will stick with my ultrasharp 40mm f/2.8.

That being said, why bother with this lens? Too close to the 35mm f/1.4, and not far from the 50mm. At least the 40mm f/2.8 pancake makes for a very light, carry-anywhere, almost a body cap type lens (not to mention, MUCH CHEAPER).

morinor

That what I though also at the beginning. But after seeing that it is actually different I find the reason why. Based that it has bigger front element and the pictures, I have a feeling that it has very good sharpness equal that of 50mm or better and less vignette. The 35mm although very good is not as good as the 50mm. Also it suffers from heavy vignette at f1.4 reaching the -3EV at the corners.
Still even for me this 40mm is not for me I am satisfied with the performance of 35mm Art. It is also half the weight.
Other will find useful, especially for video.

This is a focal length that would get a lot of use if I owned it. Kind of heavy, but perhaps worth it. Samples look good.
