Review of the Sigma 14-24mm F2.8 Art Lens

0Comments

Every photographer’s kit needs to include both a wide and ultra-wide lens. These lenses provide the flexibility to shoot a variety of subjects such as portraits, landscapes, astrophotography, and food. Wide lenses provide a unique and fresh way to portray subjects and are a great way to shoot contextual scenes that emphasize foreground elements. New to the market in 2018 is the Sigma 14-24mm f2.8 DG Art Series Lens.

It provides a constant fast f/2.8 aperture and a zoom that transforms your field of view from wide (84.1 degrees) to ultra-wide (114.2 degrees).  I took this lens for a test-drive to give you a glimpse of its performance.

I will save my very positive overall numerical rating for the end. So let’s get into some of the nitty-gritty findings of this functional and flexible piece of glass.

First Impressions

There’s always a thrill the first time you unroll a lens from its packaging and lift it from the box. I immediately noticed the weight of the lens (officially ~40oz; 1,150g) giving it a quality feel. The metal construction of this lens is on display and the only plastic parts are the lens cover and lens hood.

I was struck by the large size of the lens – it is much larger than my Sigma 24mm f/1.4. However, this makes sense as the extra size is necessary to accommodate the zoom from 14-24 mm. Overall my first impressions on the look and feel of this lens were excellent.

I tested the Sigma 14-24mm f2.8 on a Nikon D800 and Nikon 810 body. It fit that body well and has a good feel on the full frame body.

Build Quality

Sigma did not cut any corners when constructing this lens. The all-metal build gives it a sturdy feel and results in the weight I eluded to in my first impressions.

The metal construction includes the rear mount to give the lens longevity and life. The zoom ring and focus ring are textured for a solid grip and operate very smoothly. I was happy to note that the construction of this lens is dust and splash resistant which are valuable traits to me as a landscape and nature photographer.

The lens cap has a snug fit and amply covers the aspherical lens.

The lens is large (5.3 inches long) and well built. Texturing on the focus and zoom rings provide a good grip.

Image Quality

In the Lab

To conduct sharpness tests, I took the lens into a variety of conditions both indoors and outdoors.

Let’s first take a look at the results of a traditional test using the pages of a book to determine sharpness and chromatic aberration. For that test, I adjusted the camera to Aperture priority mode and adjusted the aperture throughout its range (f/2.8 – f/22). All images were shot with a tripod with the exact same lighting in a lightbox.

Individual results for each setting are available below showing a 1:1 ratio crop of the same numbers at the edge of the lens. I found the lens too soft when wide open at f/2.8. That is an expected result, but the softness was very noticeable. It was very sharp all the way to the edge of the image at f/8 and f/16. Sharpness declined at f/22. Image sharpness was maintained to the edge of the lens – impressive for an ultra-wide lens.

I found there to be a limited chromatic aberration that is easily correctable in Lightroom. Particularly in the corners of the image there was distortion at 14mm, but that is a common result in ultra-wide lenses.

Here is a test of the lens for sharpness at f/2.8 at the edge of the image. You can see blurring along the edges of the numbers which is expected at the edge of an ultra-wide lens when shot wide open.

The lens became much sharper at f/8. You can see clear, crisp lines out to the edge of the image.

At f/16 I found this lens to be even sharper than f/8. Very crisp lines out to the edge of the image.

At f/22 the lens lost some of its sharpness. This is not unexpected with a lens fully stopped down.

In the Field

Similar to the lab test results above, I cropped images at 1:1 taken in natural lighting conditions to look at the sharpness of this lens. The results showcase sharp images even when taking hand-held photographs.

In particular, you can see the lens is extremely sharp in the middle and how the stars become distorted at the edge of a crop after a long exposure.

Stars shot with the Sigma 14-24mm. This is a crop at the edge of the lens and you can see due to the long exposure that some star trails are seen. This is due to the distortion that occurs to the image’s edge at 14mm

This 1:1 crop of an eagle passing overhead shows good sharpness in the wing edges – even at the edge of the image.

Focus, Accuracy and Speed

As is my experience with other Sigma Art Series lenses, the autofocus is fast, accurate, and does not produce much (if any) noise. This lens integrates a hyper sonic motor (HSM) to pull off the noiseless focus.

A huge benefit of the lens is the small minimum focusing distance of 10 inches. That gives you, the photographer, unlimited options on what foreground element to leave in focus. In low-contrast situations such as a cloudy day the autofocus did not hunt for the subject, and focusing from 10 inches to infinity was very fast.

Shots from the Field

The images below are meant to show off the flexibility of this lens ranging from 14-24mm, the shallow depth of field you can achieve with an open aperture, and its usefulness for different subjects. I’ve featured some landscapes, people, and food that I was able to photograph.

I was really happy to have the maximum f/22 aperture to create brilliant starbursts. This is a nice creative technique for landscapes, and the ability to stop down to f/22 gives flexibility for shooting flowing water as well.

The ultra-wide angle and close minimum focusing distance allow you to put foreground elements in perspective.

Review of the Sigma 14-24mm F2.8 Art Lens - b/w photo of a tree

This tree is nearly 50 feet (15m) tall and I needed a wide angle to capture the whole thing. The ultra-wide lens tilted the tree creating a slight distortion which is characteristic of ultra-wide lenses.

Using the wide-angle to capture a whole scene along the beach. I took this image at 14mm and stopped down to give sharpness to the logs and distant mountains.

The wide aperture helped me shoot this shot in low light during a local dance.

Review of the Sigma 14-24mm F2.8 Art Lens - food photo

The minimum focusing distance is helpful for food photography and the shallow depth of field can draw your eye to foreground elements.

Increasing the f-stop can capture the depth of an entire scene. I found this useful in this food scene to emphasize the food and show off some Alaskan Brewery products, too.

Review of the Sigma 14-24mm F2.8 Art Lens - blue hour

This image was captured at 14mm. The next image was captured at 24mm with the camera mounted in the same position. These images give you insight into the field of view at a wide and ultra-wide focal length.

Pros and Cons of the Sigma 14-24mm F2.8 Lens

Pros:

  1. Close minimum focal distance – I found the 10″ focus distance to be very helpful in creating interesting landscapes and in scenes where a foreground element needed to be emphasized and placed in context with its surroundings.
  2. Fast and accurate autofocus – A solid autofocus system can be a photographer’s best friend!
  3. Flexibility – The 14-24mm zoom range gives you the flexibility to transition between a wide and ultra-wide lens. Effectively replacing two lenses is a huge benefit.

Cons:

  1. Large size – I was pretty surprised at how big the lens is, and it’s worth noting that it will take up quite a bit of space in your kit as well. Fortunately, it can replace an ultrawide and wide lens perhaps saving you space in the longrun.
  2. Lack of sharpness at wide open apertures – The weakest part of this lens is the softness at open apertures. Fortunately, it is a very sharp lens when stopped down.
  3. Aspherical glass – As a landscape photographer I like to use neutral density filters and polarizers to make the most of a scene. The aspherical dome of glass requires carrying a separate filter set.

Final Rating and Product Value

Sigma 14-24m, Review

Overall Rating : 9 out of 10 – this lens provides some excellent features, great build, and overall quality. Sharpness in the center of the image is excellent and the edges maintain sharpness as well.

My main reason for pulling this lens down to a 9 is the size of it. Those looking for a concise and smaller kit may benefit from a prime ultra-wide to decrease the lens bulk in their kit.

The value of this lens on Sigma’s website is $1,199 USD (check here for pricing on Amazon). Although that figure seems a bit high, the build quality warrants the price. You also have peace of mind knowing that the lens is effectively replacing the value of two other lenses in your kit.
