The Sigma 30mm f/1.4 DC HSM ART is basically what would be deemed a "normal" lens when used on APS-C (for which it is designed) with a horizontal field of view of 44 degrees.

With its fast maximum aperture of F1.4 it works well in low light situations and provides shallow depth of field.

The lens has a rear focusing system combined with an in-lens motor. This should ensure smooth and accurate autofocus. Quick-shift is also supported. The lens is compatible with Sigma's USB Dock, which enables firmware updates and focusing adjustments.

This lens replaces the now-discontinued Sigma 30mm F1.4 EX DC.

Lens Review Date: April 26, 2021 I can recommend this lens: No | Price: $265.00 | Rating: 7 

Pros: Fast in aperture, fast to focus
Cons: Beaten in image quality by the HD 35mm F2.8 Limited
Sharpness: 7    Aberrations: 7    Autofocus: 9    Handling: 9    Value: 6    New or Used: Used    Camera Used: KP   

(Sold in spring 2018, so this isn't based on the most recent experience).

Focus throw: ~100 degrees

Wide open, I'd rate the central sharpness as 6/10. This rises to 8/10 at f/2.8 and doesn't improve with further stopping down. The edges come close at f/5.6 and beyond.

Overall image sharpness deteriorates to 7/10 by f/11.

It's a step above a wide-normal zoom, but the 35 Limited is a step up again and that lens has virtually no CA.

- CA at all apertures
- Vignettes until f/2.8
- Mild yellow colour-cast when comparing same subject with different lens

CA is noticeable wide open, improving to minor at f/2.8 and it stays at that level through the narrower apertures. I'd say it's equal parts green and purple.

Obviously more noticeable with some subjects rather than others, the colour-cast can be discerned when reviewing pictures after changing lenses, but could be mitigated by adjusting the Custom Image settings away from yellow. I generally use the Bright setting, which is probably the worst for this.

Wide open shooting is not my style.

Excellent. It may be broad, but it's comfortable for the left hand to support it and the camera. It may be dense, but its stubbiness doesn't shift the centre of gravity much: the combination is still manoeuvrable.

It's wide and has a focus throw of around 100 degrees - manual focus is no problem.

The lens hood is reasonable, but when reversed there is a gap between it and the lens body. A flower/petal design would be more compact, at the cost of protuding more forwards when mounted. I don't recall if I used any filters or what vignetting they might cause, but the lens hood permits good access.

I had no issues with focusing - the HSM motor is quick and quiet. Remember to configure the AF Fine Adjust setting on your camera.

No. Unless you absolutely need precisely this focal length or f/1.4 aperture. The Pentax (HD) 35mm F2.8 Limited is a better lens.

Lens Review Date: November 30, 2020 I can recommend this lens: Yes | Price: $200.00 | Rating: 10 

Pros: sharpness, bokeh, low aperture
Cons: none
Sharpness: 10    Aberrations: 8    Bokeh: 10    Autofocus: 8    Handling: 10    Value: 10    New or Used: Used    Camera Used: K-3 II   

I am not a fan of shooting with widest aperture possible on any lenses. I just dont like those pictures and i have a headache of it. : ) I tend to stop down one or two steps all the time, and then i feel the mixture of sharp objects and blurry objects are becoming in sweet balance. Therefore i dont have ANY problems with this lense at all. Because all negative aspects disappear with F2, even the aberations are gone.
My piece is very well performing the autofocus. So the other reviewers, who feel it is a weak point, must have a dying motor inside, or the lense is asking for calibration. Although, i rate it with 8 out of 10, because at slightly lower light conditions, when i instantly put this lense on the body, the performance is not that great. But it is rather my mistake that i try to take pictures in the basement : ))

Mayyybe one small negative, it is a little heavier than i had expected. But anyway, when it first came to my hands i could immediately feel the quality and its perfect design. It is not only good working, but also hell of a good looking lense!

Beautiful and extremely good lense which i can recommend highly. Get it when you have chance.

Lens Review Date: August 3, 2020 I can recommend this lens: Yes | Price: $500.00 | Rating: 9 

Pros: Sharp, compact, and affordable
Cons: No weather-sealing.

Hi all,

Sorry about barging in, as I rarely use my Pentax gear nowadays (got one camera and one lens, just as my wife does). But I got this lens!

I got this lens a few years back, and it is one that impresses me a lot, in DX format (or smaller).

It can be used on FX bodies, but you need to crop the extreme corners of your image, as the vignetting is a bit extreme, and the sharpness isn't the best there. A simple 16:9 takes care of the issue and then you just need a slight adjustment of the vignetting, if any at all.

I use it on all my cameras (except the Pentax K-x), from 1" to FX cameras, with no regrets at all, for all kinds of jobs, but mostly close-up.

Even better for close-ups if you add a close-up filter, like the Canon 250D (58mm size) + a 62-58mm step-down ring.

Delightful lens, small and compact, what more do you need.

Lens Review Date: November 30, 2018 I can recommend this lens: No | Price: $500.00 | Rating: 6 

Pros: Sharpness in the center
Cons: Chromatic aberrations, Purple fringing, Distortion, Flat rendering
Sharpness: 9    Aberrations: 2    Bokeh: 7    Autofocus: 8    Handling: 7    Value: 5    New or Used: New    Camera Used: Pentax k500   

Hello! I have used this lens about 10 months and I've sold it for my first limited, 31 of course! I won't make a comparison with 31, just my observations. The lens it's sharp no problem with that, autofocus was good with point focus... But, there are too many buts... The first one it's chromatic aberrations and purple fringing, they are coming together! Let's see: Crop left: Crop right: This image was shot at f5.6 but I can tell you that even at f11 still could find aberrations! Let's see a winter shot: Left crop: As you can see, bad CA... Let's look at the bokeh: And right crop: When you have done with those troubles you have to deal with distortion: For me, not an acceptable distortion. Well, when you have done with that you got to pp colors, contrast an other things, because to my eyes the rendering it's rather flat in comparison with what pentax lenses can deliver. Conclusion: This surely ain't an art lens and should not considered as one. It' s better than the previous Sigma but not at the bokeh chapter, it's got good sharpness but too many caveats, which I can't accept!

Lens Review Date: November 21, 2018 I can recommend this lens: Yes | Price: $500.00 | Rating: 9 

Pros: Sharp, Attractive yet Sturdy, Smooth Bokeh, Compact, Versatile
Cons: Low Contrast Wide Open, Dodgy AF, Heavy for its Size
Sharpness: 10    Aberrations: 8    Bokeh: 10    Autofocus: 5    Handling: 9    Value: 9    New or Used: New    Camera Used: K-70, K-3 II   

I purchased this lens in hopes of finding a reliable low light prime that I could use for a bunch of different applications. The 35mm version of this lens was out of my budget. I do a lot of indoor concert work and so having something like this was important. Despite the prolific (and true) statements about the AF, I decided to give it a go anyway. Very happy I did.

About the AF: Yes, it's bad. It's the only lens in my kit that I never use all the AF points on my camera with. It's just too unreliable in those regards. It doesn't hunt as much in good light but it is not accurate enough; especially for something that is advertised as a premium lens. I use this lens in a very challenging lighting situations and have pushed it to its limits. In dynamic, strobe lighting, I almost always go Manual. Tough lighting situations will confuse the AF and cause it to hunt for long periods of time. In other situations, I simply use a single AF point and adjust on the fly. This may be more work than others want to do. I didn't mind and the result of doing this on my K-70 resulted in much greater consistency. I used this lens on the K-3 II and I had way more trouble nailing a good shot. I suspect the K-70 being more modern affects its relationship with this lens in a positive way. Either way, I can't complain. This lens has produced some of my best work. I can't use all of the AF points on the camera reliably like I can my Sigma 17-70 for example but the image quality and how versatile it is makes up for it my opinion.

It's a wonderful lens only let down by its dodgy AF; which can be worked around. But the fact that I have to is why I give it a 9 and not a 10. I'd actually give it a 8.5 but I think it's closer to 9 than a 8. If you can deal with that, you'll be taking some gorgeous photos.

Lens Review Date: May 26, 2017 I can recommend this lens: No | Price: $400.00 | Rating: 5 

Pros: Versatile focal length and aperture, decent IQ
Cons: Pants-on-head-retarded AF, purple fringing
Sharpness: 8    Aberrations: 6    Bokeh: 8    Autofocus: 3    Handling: 7    Value: 7    New or Used: New    Camera Used: K5II   

The sharpness is good, sure, but not worth playing Sigma Autofocus Roulette for.

Doesn't matter how carefully I calibrated the microadjustment, the lens would randomly miss focus completely on maybe 4/10 shots. Good light, bad light, BBAF, centre point only, nothing made a difference. i don't mean it was slightly soft or it locked focus on the background etc, I mean it'd be a totally unfocused, unusable shot. Tried using it for one model shoot and the a commercial job, and immediately sent it back. For £300 this should be the best damned walkaround lens on the planet, but Sigma's crappy AF makes it impossible to trust.

The detail and rendering is nice even at f1.4, but this comes at the price of pretty severe purple fringing, which seems to get WORSE as you stop down. Bizarre, I can only assume Sigma is building the ART lenses to look good in the all-important MTF charts rather than as balanced, useful tools.

If, like me, you're reading this thinking 'I'll be able to live with the dodgy AF if the image quality is really good' me, you won't. This isn't something you can fix with microadjustment, the USB dock, focusing technique etc, it's just inconsistent. By all means give it a try, but only from a retailer with a decent returns policy.

Lens Review Date: June 15, 2015 I can recommend this lens: Yes | Price: $345.00 | Rating: 7 

Pros: Sharp, nice designed, quite, comfortable to hold with lens hood attached, affordable, good in low light
Cons: bit short for big hands to hold without lenshood, unreliable AF, not weathersealed, heavy
Sharpness: 9    Aberrations: 8    Bokeh: 9    Autofocus: 5    Handling: 8    Value: 8    New or Used: New    Camera Used: K-30   

As my first prime lens, i am sort of underwhelmed but still amazed by it's performance. I was looking for a replacement for the DAL 18-55mm f3.5 kit lens as light travel compagnion. Well, the Sigma is quite heavy for it's size BUT its extremely well build and definitely looks nice on camera. But still feels like it would weigh more than the K-30's body ... "Why would you get a Sigma Art Lense for light travel?" some might ask. Because I feel arty myself, that's why. And it strengthens your arms!

After a lot of time fiddeling around, producing unusable pictures and learning how to work with it, it produces beautiful results! Step down to f5,6 and you can crop the *§$# out of the pictures. Though a bit of barrel distortion, some vignetting and the colours it produces make for some fine, arty looking pictures.

As I said, I purchased it as walk around travel lens. When shooting the streets, you don't scare people with focus noise (the K-30's shutter will do that for you) and you got that one opportunity to fire at animals, before they flee. Its 30mm focal length is wide enough for landscapes and where possible, zooming in with your feet is always a fun thing to do.

So let me address my one and only problem what makes this lense quite hateful: The AF. If you use Live View, contrast autofocus will does its job perfectly, even at f1.4 and your object some meters away. Well, if you use the viewfinder, this lens will miss a lot of shots from f1.4 to at least f2.8. A LOT. Some are precise, some are not.
So it makes you start working on you MF-skills, so i would to some degree recommend the lens for rookies like me. This time, the machine will NOT do everything for you, oh no. Think for yourself! Want prefocus? You got the focus-distance-scale on the barrel and anticipate what's going on in front of the lens. Got lazy because of super-zooms? Use your feet to get into action.

And one last thing: It feels af if contrast autofocus and phase detection work the same speed.

Got other primes? No need for this one. Want your first prime and you feel, the big "A" on this lens appeals to what you want to achieve with your camera, go for this lense!

Some examples:

EDIT: Downgraded Autofocus (-1) and overall rating (-1) after a bit more usage.

Lens Review Date: December 5, 2014 I can recommend this lens: Yes | Price: None indicated | Rating: 9 

Pros: Wide aperture, doesn't feel cheap
Cons: auto-focus hunts and inaccurate
Sharpness: 9    Aberrations: 8    Bokeh: 10    Autofocus: 7    Handling: 9    Value: 9    New or Used: New    Camera Used: K-3   

Fantastic lens! Very sharp wide open (when you manage to get the focus right). Great for portraits, low light situations.
I already had an old Pentax A50 f1.4 which was producing soft shots wide open due to diffraction issues. Also, 50mm was getting a bit too narrow on aps-c. 30mm is just perfect.
The lens is a pleasure to use, very well constructed. The auto focus definitely has issues, but I think this kind of lens works best in manual focus anyways.

Lens Review Date: May 22, 2014 I can recommend this lens: Yes | Price: $490.00 | Rating: 9 

Pros: Sharp, HSM focusing, somewhat compact
Cons: Still bigger than I like for K-01, CA wide open, focusing issues on DSLRs
Sharpness: 9    Aberrations: 8    Bokeh: 10    Autofocus: 9    Handling: 8    New or Used: New    Camera Used: K-01, K-5II, K-30, K-r, K-x   

If you are looking for a fast lens with "standard" Field of View on APS-C and HSM focusing, there aren't a lot of choices, and even fewer that weigh less than 500g/1 lb (my limit for use on a K-01). The Art 30 is a very good lens, and can get excellent results, but you need to be aware of its limitations. Wide open, in bright light or with high-contrast subjects, there is chromatic aberration/purple fringing even in the center. Corners are sharper than the older Sigma EX 30, although still a little soft at wide apertures (and CA adds to that).

It's kind of large for a walk around lens and not subtle at all with the hood installed. It is flare resistant enough to use without the hood even outdoors in bright sunlight.

I can confirm the slow AF/no AF problem on newer DSLRs, but it only seems to happen in 11-point/5-point auto-select AF mode. Using center point or select-point AF, the lens focuses as fast as any of my screw drive lenses. The K-01 does not have any problems with this lens.

I am totally impressed by this lens. I rarely had a lens that already so can be a great sharpness at maximum aperture. With the auto focus so far I could not detect any problems. In contrast to other statements, the autofocus is true for most images.

Lens Review Date: April 11, 2014 I can recommend this lens: Yes | Price: $499.00 | Rating: 9 

Pros: Very sharp, superb built, nice feel, accurate focus
Cons: Min focusing distance longer than spec
Sharpness: 10    Aberrations: 8    Bokeh: 10    Autofocus: 8    Handling: 9    Value: 10    New or Used: New    Camera Used: Pentax k-01   

I have been using this lens on my pentax k-01 for over 3 weeks now. I don't have any focussing issues per se. I have tried 90% of my shots in very very low light just to put this through the ringer. It does struggle when focus distance is under 2 feet. Sometimes I have to go manual to get it to focus very close. It is possible that the min focusing distance is more than what the lens spec says. It is very sharp wide open and superbly built. Beautiful lens. Not sure if this is because k01 is mirrorless and used only CDAF done by the camera software. I love it so far.

Pros: very sharp, 1.4, modern colorful, fill the lack fix 30 of Pentax
Cons: Ca from 1.4 - 2 (not important because of Lightroom), HSM very silly
Sharpness: 10    Aberrations: 8    Bokeh: 9    Autofocus: 5    Handling: 9    Value: 8    New or Used: New    Camera Used: K3   

I need a wide lens with large open Apeture 1.4 ( only SMC FA 31 1.8 but too expensive) so I decided to buy the only cheaper lens.... It's Sigma 30 1.4 Art.
That's great and exciting more and more.
The Sharpness 's so surprised...i'm very very satisfied...on my K3 (no AA filter)
color made strong impression on me.
But the AF on lens 's very stupid, slower than DA * 55..with my K3, I am trying to find the way to increase the speed and the accurate AF HSM...
Some Pics take from my lens ( max apeture 1.4)
