SIGMA 60-600mm f/4.5-6.3 DG DN OS Sport lens review

The Sigma 60-600mm f/4.5-6.3 DG DN OS Sport is one of those lenses that instantly grabs your attention simply because of how ambitious it is. Covering everything from 60mm all the way up to 600mm with its powerful 10x zoom, it’s designed to handle wildlife, sports, aviation and even some landscape photography without needing to swap lenses.

On paper, that kind of flexibility makes it sound like a serious contender among the very best zoom lenses for wildlife photography, particularly for photographers who don’t want to carry multiple lenses out on shoots. But it has one major caveat: it’s insanely heavy.

We took it to a nature reserve to put it through its paces and test its performance in real-world conditions, and see for ourselves how that hefty weight feels in practice.

• Uncomfortably heavy
• Solid build quality
• Feels very sturdy

The Sigma 60-600mm f/4.5-6.3 DG DN OS Sport lens feels exactly like what you’d expect from Sigma’s sport series — big, solid and built like it could survive a few knocks. It’s definitely not a small or lightweight lens, though, and we found ourselves struggling to hold it for long during wildlife sessions, to the point where the 5.5-pound (2.4-kilogram) weight tipped it into "too heavy" territory and it became somewhat of a chore to shoot for long. The weight is especially cumbersome when tracking birds in flight, but the silver lining of the extra heft is that it feels incredibly sturdy as a result.

The zoom ring is smooth. We did notice a tiny bit of lens creep every now and then, but this was nowhere near as severe as it was when we tested the Sigma 150-600mm f/5-6.3 DG DN OS lens. There’s no shortage of physical controls, either. There’s an AF switch, stabilization controls and customizable buttons all around the barrel. The removable tripod foot is solid, too, and balances the lens nicely on a tripod.

SIGMA 60-600mm f/4.5-6.3 DG DN OS Sport: Performance

• Lovely image quality
• Good autofocus in reliable light
• Image stabilization helps when shooting handheld

Performance is impressively strong considering the massive zoom range this lens covers. The sharpness is excellent through most of the range, especially through the shorter and mid-range focal lengths, with plenty of detail and contrast straight out of the camera.

The autofocus performance was also better than we expected for such a large telephoto zoom. Paired with Sony’s autofocus and subject detection, the lens tracked birds and wildlife reliably in good light, and the focus was fast and sticky. The image stabilization is a huge help when shooting handheld, and we were able to get sharp shots even at 600mm.

We photographed some test charts to analyze the image quality, and shooting wide at 60mm gave the best result at the wider apertures. Going all the way up to f/11, the image becomes very soft in the center. Zooming in to 200mm improves things, where the image is sharpest with the best contrast at f/5.6. At 400mm, f/5.6 and f/8 are very similar, with f/5.6 having the edge slightly, whereas at full zoom at 600mm, f/8 produced the sharpest images — although the 600mm images were the softest overall.

However, it’s worth noting that although we made these assessments while pixel-peeping at the test chart images, the real-world images we took at a nature reserve were mostly all taken at 600mm, and the image quality is still beautiful, even after cropping.

• Very versatile focal length
• Good close focusing distance
• Overkill if you won’t use the wider focal lengths

In use, this lens’ biggest strength is its versatility. Having everything from 60mm all the way up to 600mm in a single lens makes it much easier to react quickly when subjects move. For wildlife photography especially, we found it useful when birds flew towards us, since we could zoom out instantly rather than miss the shot entirely.

That said, the huge zoom range can feel a little excessive, but this will depend on what style of photography you do. We found ourselves staying closer to the longer focal lengths for wildlife work, which is fine if you’re a dedicated wildlife shooter, but it does beg the question of whether a smaller, lighter telephoto zoom lens would be a more practical option for some photographers, particularly for those who stay at the wider end.

We also liked how close the lens can focus, particularly on the wide end. It’s not a macro lens, but being able to shoot closer to the subject without changing lenses adds even more flexibility when shooting outdoors.

The big questions you need to ask yourself here are: "Are you fine with a heavier lens?", "Are you bothered about having a shorter close focusing distance?" and "Do you shoot wide?". If you answered yes, then it makes sense to get this lens.

If, however, you want a slightly lighter lens and you don’t need the wider focal lengths, we’d suggest going for the native Sony FE 200-600mm f/5.6-6.3 G OSS lens instead. For us, the weight of the Sigma felt significantly heavier than the Sony, to the point where it would make us think twice about investing in it, particularly as the Sigma is the more expensive option.
