Sigma 45mm f/2.8 DG DN Contemporary Overview

Designed for full-frame Leica L-mount mirrorless cameras, the fast and versatile Sigma 45mm f/2.8 DG DN Contemporary Lens is a normal-length prime that optimizes size as well as weight while rendering notably smooth bokeh with rounded out-of-focus highlights in both the foreground and background. Coupled with its ability to soften the periphery of blurred images while enhancing the three-dimensional impression of an object, its 9.5" minimum focusing distance makes it suitable for snapshots to tabletop photos, or any imagery where you wish to make your subject stand out.

Though full-time manual focus is available, this lens is equipped with a stepping motor that enables smooth, high-speed autofocusing that is notably quiet whether utilizing features such as Face/Eye Detection AF or during video shooting. A rounded seven-blade diaphragm contributes to the smooth bokeh, and a lens hood is included, which can protect the front element as well as prevent stray light from causing flare.

As part of the Contemporary line within Sigma's Global Vision series, this lens is designed to achieve a balance between convenience and performance, and meshes a compact, lightweight build and versatile handling with notable optical attributes.
Created for full-frame Leica L-mount mirrorless cameras, this prime, normal-length lens is designed to deliver excellent image quality while optimizing size and weight. It is also suitable for APS-C models where it provides a 68mm equivalent focal length.
Optical design controls spherical aberrations to help endure large, soft, rounded bokeh while enhancing the three-dimensional impression of the subject.
Constant f/2.8 maximum aperture is well-suited for working in available light conditions and provides greater control over depth of field.
A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance. Full-time manual focus control can also be selected.
Rounded seven-blade diaphragm contributes to a smooth and pleasing bokeh quality.
The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.

Sigma 45mm f/2.8 DG DN Contemporary Reviews

Good. Not Excellent.

By Gary
Rated 4 out of 5
Date: 2022-04-10

This is the second time around for me with this lens. The first time I had this lens I found it excellent and 5-star on a Leica SL1. Sold that camera and then this lens. Now I have an SL2 and re-bought this lens. Overall it is not as sharp nor as contrast-y on the SL2 when shot at f2.8. If I stop down to f4 sharpness and contrast does pick up a bit (but not a lot). By comparison I also have the Sigma 30mm f1.4 L mount APSC lens. When I use that lens on my SL2 images, even shot at f1.4, images are sharper and do have more contrast. However, taking into consideration the fact this lens costs one-tenth the amount of a similar Leica Summicron SL lens, I'd say this lens is worthy of the 4 stars I give it.

Great Street Photography Lens

This is a truly wonderful lens with its own look at a terrific price. The Leica APO lens are also beautiful, but they are heavy. The Sigma 45mm is very light and will turn your Leica SL into an everyday camera you can take anywhere. I use this lens for my street photography and the heavier APO lenses for my commercial and studio work.

A rewarding lens when you play to its strenghts

Some reviewers have commented how this lens is soft when close to a subject. Even though this lens claims to have a short focus distance, I don't believe that this is what that lens is made for. When focusing at subjects that are more distant, this lens is very sharp and offers a lot of detail. I used this lens on a Panasonic S5 and it works flawlessly. It is quick to focus and provides great results. The lens has an aperture ring on it. So, if you're coming from a Fuji system, you'll feel right at home. If you prefer to adjust the aperture setting from the camera, you can do that too. This lens is versatile, unique, and a lot of fun to use. What makes it great is that it isn't your typical nifty fifty. It has character. If that character is appealing to you, it will quickly become a go-to lens in your kit.

Surprising close-up performance

I bought this lens to keep on my SonyA7RIV as a standard normal lens. What I did not expect was that if the sensor is set on APS-C, the lens does quite well as a macro lens. When set for full-frame use, the lens focuses down to 1:4. On APS-C the close focusing approaches 1:2.5 and as only the central portion of the image is used, the image quality is superior, because of the 61mp full-frame sensor. I am truly pleased with this camera-lens combination, and would recommend it.

I got this lens because of the good reviews. It is very light for my Leica SL2-S. The focusing is fast and the results are excellent.

Handle alternative

My prime lenses for Leica weigh a ton, and it is nice to have this relatively lightweight glass to fall back on when mobility and flexibility are needed. Images are more than adequate and the price, of course, is a fraction of what my 50mm prime cost. Worth having for those time when a simple snap is called for.

Must Have Lens for Leica SL System!

By David

This lens behaves like 2 different lenses in one. Wide open it is very sharp in the center but provides a very soft Bokeh in front and behind it. Stopped down to f4 or higher it becomes sharper still ( right out to the corners ) and contrast increases. Wide open portrait shots are sharp yet 'dreamy' and soft in the background - at f4 and higher it performs like a modern lens and 'draws' accordingly. A true bargain at twice the price!
