Sigma Af 35mm F/1.4 Dg Hsm Art Review Essay

One of the first lenses in Sigma’s Art series, the Sigma 35mm f1.4 DG HSM appears to suit a range of applications. Portrait photographer Mark Stephenson takes a closer look in his review.

 

 

In late 2012, Sigma announced it was going to shake up its lens classifications, placing each new lens into one of three categories: ‘Contemporary’, where you’ll find your basic zoom lenses; ‘Sport’, for the more high-end telephoto lenses; and last but not least, the ‘Art’ category, for more specialist lenses, including large-aperture primes. The Sigma 35mm f/1.4 DG HSM lens fits firmly into this last category, and if this first ‘Art’ lens is anything to go by, I could very well end up with several more in my bag in the future.

When the Sigma 35mm f/1.4 DG HSM was announced, it was met with a mixture of excitement, hope and scepticism. The lens sounded fantastic on paper and the MFT charts showed the lens to potentially be very sharp, but unfortunately Sigma had gained something of a bad reputation in the past from rumoured poor quality control; the internet is rife with people complaining about their old Sigma lenses not being up to scratch.

Furthermore, this lens was going toe-to-toe with one of the most popular Canon lenses, the Canon EF 35mm f/1.4L USM. A favourite among wedding, portrait and event photographers, the Canon EF 35mm f/1.4L USM delivers great optics inside a renowned L-series body. It’s also been around for a while – since 1998 to be specific – so it’s had plenty of time to find a place in many a photographer’s bag.

 

Key Features

  • Large maximum aperture of f/1.4
  • Fixed 35mm focal length
  • HSM (Hyper Sonic Motor) and inner focusing system
  • ‘Art’ classification
  • 0.3m minimum focusing distance
  • 9-blade aperture

The 35mm focal length is a favourite for many photographers, and one many photojournalists will be more than used to. It offers a useful and versatile field of view, capturing a good amount of a scene without feeling overly wide, nor too tight and cramped. When mounted on a camera with a cropped (i.e. smaller than full-frame) sensor, this lens feels slightly longer, equivalent to around 56mm.

The thing that most excites me about this lens is the amazing pairing of the 35mm field of view and the big, bright maximum aperture of f/1.4. The combination gives you 3D-like images with a wonderful quality, while the latter allows you to achieve a relatively shallow depth of field.

 

 

That combination of semi-wide focal length and large maximum aperture is hard to beat. The subject isolation is never going to be as defined as with an 85mm lens or similar, but on the wide field of view it looks great.

It’s also a fantastic combination for event photographers, such as those shooting weddings. When light is outside the control of the photographer, this lens really shines as it allows you to shoot in very low light levels with a usable shutter speed, all the while keeping the ISO in a good range.

 

 

Although this review is focused on this lens in the Canon mount, it’s also worth noting that it’s available for four other mounts: Nikon, Pentax, Sigma and Sony.

This lens has another unusual trick up its sleeve in the form of compatibility with the Sigma USB dock. You can find an in-depth review here but its main party piece is that it allows owners to calibrate the autofocus themselves rather than having to send it off to be done by Sigma.

 

Design and handling

The design of the Sigma 35mm f1.4 lens is definitely something to admire; its sleek, minimal, industrial body would not look out of place in an Apple shop. I know there’s probably a fair few of you shouting out right now about how a lens is merely a tool to capture images, but I can’t help but heap praise on Sigma for this gorgeously designed optic.

 

 

Not only does it look great but it also feels fantastic in the hand as well, with a nice, reassuring weight. Any thoughts that this is a cheap, third-party lens are a million miles away when you’re handling and using it. The focus ring is big and perfectly dampened and the only switch on it, the AF/MF switch, has a confident snap when toggled back and forth.

The lens is also supplied with a petal lens hood that fits snuggly to the front of the lens to prevent flare and protect the front element. There’s also a padded pouch for storage included in the box.

 

AF performance

 

 

The autofocus on this lens is fast and accurate. Granted, I’ve not used it for indoor sports or anything too demanding, but it can happily track a model walking towards and past me, or a person on the beach for a lifestyle shoot. The Hyper Sonic Motor (HSM) ensures noise is at a minimum, while the internal focus design means the length of the lens remains the same when focusing, unlike on some others.

 

 

The minimum focus distance of the lens is 300mm; this provides you with a magnification 0.19x. This is nowhere near macro but it would be unfair to expect a lens of this type to excel in this area. In use, I’ve found this distance to be more than adequate.

 

Image Quality

This lens really shines when it comes to image quality. Being a prime lens it is very sharp, especially in the centre of the frame. Wide open at f/1.4 the corners are not quite as sharp but stepping down past f/4 will provide razor-sharp images from corner to corner. It is also nearly distortion free, with very slight barrel distortion. This is achieved in part by the aspheric lens at the front of the lens series.

 

 

When looking at any prime lens it is important to look at the bokeh. This is the quality and rendering of the out-of-focus areas. The Sigma 35 f/1.4 has a 9-blade circular aperture that, to my eyes, produces very nice bokeh. It’s not going to have the same creamy effect of a longer lens, but it does produce smooth and pleasing blurred areas that really pop out against the sharp and focused ones.

 

 

Vignetting on the Sigma 35mm f/1.4 is very apparent wide open although, just like with corner sharpness, this can be resolved by stopping the aperture down. For my use, I actually find the vignetting to be no problem at all as I often add a slight vignette to images to draw the viewer into the middle of the photo.

 

Verdict

There is something unique about this lens. The combination of the focal length, sharpness, shallow depth-of-field, bokeh and even the vignetting means this lens produces wonderful images. For the kind of images I shoot, which are environmental portraits and lifestyle shots, it’s a winning combination. This lens is one of the first in my bag for location portrait shoots or weddings; if you told me I had to weld a single lens onto myCanon 5D Mark III, the chances are that this would be the lens I would pick.

It works absolutely brilliantly for environmental portraiture, as well as events, travel and documentary photography. I could see myself happily travelling with just this lens and it’s always in the bag for any events I shoot. Shooting at a kid’s party? It’s a great focal length to get in close to the action, and while the large aperture will help isolate your subjects, the focal length will still include the environment in the beautifully rendered background.

Sigma deserves credit for this lens and the new ‘Art’ category it has defined. If this is anything to go by I will be keeping a close eye on any new lenses that come out of the Sigma factory with an ‘A’ embossed on the side. The quality of my particular lens leaves nothing to be desired and there’s no talk in internet forums about inconsistent quality control.

Pros

  • Unique images at 35mm and f/1.4
  • Great image quality
  • Nice bokeh
  • Gorgeous industrial design
  • Good value

Cons

  • Not weather sealed
  • Vignetting wide open

How to shoot better portraits

review: Sigma 35mm f/1.4 ART lens

I have to admit upfront that I am a lens snob. Not so much for a lens being esoteric or collectible, but rather that I have a particularly strong preference for the name brand lenses. When I shot with Pentax way way back, I only used Pentax lenses. Similarly, I only have Canon lenses for my Canon bodies, and Nikon lenses for my Nikon cameras.

Part of it is that the styling of the lens and camera is more consistent. Yes, I do like my cameras to have a certain aesthetic appeal. I know, I know … how pretty a lens looks has no real correlation to how spectacularly it performs. But actually, there is a correlation of sorts. The spendier equipment (which performs well), tend to be designed to look good. But I digress.

The main reason though why I keep within a certain brand, is that the top names tend to have the top lenses. Generally, staying with the big camera brands is a decision that can be made with confidence.

My interest was piqued though by the news that Sigma is releasing new lines of lenses, and tightening up their quality control. From Sigma’s website: “all newly produced interchangeable lenses from Sigma will be designed for and organized into one of three product categories: Contemporary, Art and Sports. Each line has a clearly defined concept to guide shooters in the selection of the right lens for their photographic interests”.

One of the first lenses to be released, is the Sigma 35mm f/1.4 DG HSM wide-angle lens:

The lens has a noticeably different look than Sigma lenses in the past, and actually looks quite sleek and modern, but this all wouldn’t mean much, if the lens didn’t perform spectacularly, and was at a more affordable price point than the Canon and Nikon equivalents:

 

I mean, this lens really looks good. It also feels like it was crafted with precision, and it has a nice heft in your hand. It feels solid.

 

Prices for 35mm f/1.4 lenses

The Canon lens has an excellent reputation, and is $1480

The Nikon is a also an excellent optic, and is priced around $1700

The Sigma comes in at a very favorable $900 in comparison.

 

Optical performance of the Sigma 35mm f/1.4 DG lens

This lens is sharp. In comparison to the Nikon lens, I couldn’t really distinguish a difference. If you were to mix the files, (for each aperture), it would be difficult to tell them apart in terms of center and edge sharpness.

I added a folder with a sequence shot with the Sigma lens, from where the high-res RAW files can be downloaded. The images where shot with the Nikon D4. The images are obviously not proper test images with calibrated charts shot under controlled conditions. But they will give you and idea of what to expect.

At f/1.4 there is the expected reduction in contrast compared to the other images. The very edges have a slight image softness compared to the center, but it looks really good for a fast prime. There is also the expected vignetting when shot wide open, but this is quite mild. Anyway, vignetting is rarely a bother. We know this happens, and most often, it enhances the look of the photograph’s wafer-thin depth-of-field. I never lose sleep over the fact that lenses show vignetting wide open. It’s just another characteristic we embrace … or at least accept.

This lens, like most (or all?) wide-aperture primes, lose some light at widest aperture. Meaning, there is about 1/2 stop less light at f/1.4 than you might expect.

Keep in mind that f/1.4 isn’t really f/1.4 for most (all?) wide-aperture primes.
This means you very well might not get that extra shutter speed / ISO setting you desire when you open up.

For example, with these wide primes, if you have: 1/125 @ f/2.8
it doesn’t directly translate to: 1/500 @ f/1.4
when you look at the brightness of the image, or the histogram.
You lose about 1/2 stop. This is true for this lens as well.

Regarding the bokeh – it is surprisingly smooth for a wide-angle prime. I really liked how this lens rendered busy backgrounds.

 

Using the Sigma 35mm f/1.4 ART lens during a photo session

I had the pleasure again of photographing Nicole Jolly, a model I met during some of the After Dark photography events where I taught classes.

Nicole and I took photos in and around Jersey City and Hoboken. This image with the blue background was shot at f/1.4 and the high-res file is super-crisp. As much detail as you could want. Of course, even with the background so close to her, it starts melting away with the shallow depth-of-field that the wide aperture allows.

 

This image was shot at f/1.4 as well, but with off-camera speedlight in a small Lastolite 8.75″ speedlight softbox (affiliate). Again, the super-shallow depth-of-field should be noticeable … even for these photos scaled down to web-size. That minimal DoF definitely adds a certain look to photographs that f/5.6 just can’t. For this flash-lit portrait, I had to go into high-speed flash sync.

This photograph, also shown at the top, was shot at f/1.4 in very bright light. Of course, the shutter speed had to be 1/8000 (at 100 ISO) to allow such shallow depth-of-field. The light on Nicole is from the metallic sundial below her, reflecting light upwards.

Checking the sharpness of this lens continually during the shoot, by zooming in to 100% magnification on the camera’s preview, it was reassuring to see how sharp the photos were. You could count eye-lashes. It’s that kind of sharp, even with the aperture wide open. The lens’ focusing is also fast and confident.

 

Summary

With numerous test images I shot with this lens, and in using it on a photo-session with a model, this lens was stellar. I’d easily recommend it. And that is saying something coming from a name-brand lens snob.
