Sigma 10-18mm f/2.8 DC DN Review: Compact With Some Compromises

Introduction

Hey, welcome back Peta pixel viewers! It’s Chris Nichols here, and we’re out enjoying the last of the beautiful Alberta fall colors. We’ve brought a nice lens with us, the new Sigma 10-18mm f/2.8. This thing is tiny, and I can’t wait to go use it. I’m using this on a Sony A7 R5, and I know that might seem strange at first, but this lens is coming out on L Mount, Sony E Mount, and Fujifilm X Mount. In cropped APS-C mode, I’m getting 26 megapixels, which is comparable to a Sony Alpha camera APS-C or a Fujifilm XT camera. So, I think it’s going to be a good test.

Compact Design

Sigma calls this the world’s smallest ultra-wide APS-C zoom with an f/2.8 aperture, and I find it hard to disagree. It is absolutely small and lightweight, with a 67mm filter thread and only weighing 255g. The lens comes with a hood, which is a push-on design that locks in place with a small twist. The zoom ring is located right up against the lens hood, making it easy to operate. There is also a manual focus control ring, but no AF/MF selector switch.

Multifunctional Macro Lens

The Sigma 10-18mm f/2.8 proves to be a versatile macro lens as well. At 10mm, it works best for macro photography, providing a working distance of about 4.6cm from the front element. This allows for dramatic close-up shots with a 1:4 life-size reproduction. The lens also has good close-up capabilities, pushing the background far away and creating striking images.

Flare and Sun Stars

When it comes to flare resistance, Sigma always does a great job. The lens coatings are good, and even when shooting with the light source in the shot or just outside the frame, washed-out areas are minimal. However, ghosting can be observed, especially when stopping down. The lens also disappoints in producing sun stars, as they appear broad and messy instead of distinct points. So, when shooting landscapes, it’s advisable to be careful around sunlight to avoid ghosts.

Smooth Focusing and Bokeh

The lens features a stepping motor, which is silent, smooth, and quick enough for most situations, despite not having an advanced linear motor. Bokeh, though not a major concern for ultra-wide lenses, can still be tested. At f/2.8, shallow depth of field can be achieved, creating a swirly effect with a fair amount of cat-eye-shaped highlights. Stopping down the lens, the seven aperture blades create polygonal-shaped highlights with a distinct soap bubble effect. The transition from in-focus to out-of-focus areas is smooth, although the specular highlights can be distracting.

Minimal Lens Breathing and Sharpness

The Sigma 10-18mm f/2.8 exhibits minimal lens breathing when focusing, making it ideal for video applications. The lightweight design makes it suitable for gimbals and vlogging, without experiencing any noticeable field of view shift. In terms of sharpness, the center is decently sharp at 10mm and f/2.8, with a contrast improvement observed at f/5.6. The corners may appear slightly soft at f/2.8, but stopping down to f/5.6 helps improve sharpness.

In conclusion, the Sigma 10-18mm f/2.8 DC DN is a compact lens with some compromises. While it offers excellent macro capabilities and flare resistance, it falls short in producing distinct sun stars and may have distracting specular highlights. However, its smooth focusing, minimal lens breathing, and decent sharpness make it a suitable choice for various applications.
