Sigma 28-70mm f/2.8 EX DG Lens Review

www.the-digital-picture.com

The Sigma 28-70mm f/2.8 EX DG Lens features a fast, fixed 9-blade aperture ranging from f/2.8 to f/22. Like the Sigma 24-70mm f/2.8 EX DG Lens, the Sigma 28-70mm f/2.8 EX DG Lens is a well-built, well-spec'd lens with a value price. But, giving up 4mm of focal length range on the wide end results in a much more compact lens. The Sigma 28-70 is a solidly built lens. As it often does, solid translates to a rather heavy weight for the small size. Measuring a trim 2.9" x 3.4" (74 x 87.2mm), the 28-70 weighs 18.1 oz (510g). At 70mm, the lens barrel extends an additional 1" (23.4mm) or so. I like the forward-positioned focus ring as I generally hold my lenses near the rear of the barrel - and don't want to accidentally change the focus setting or have the ring turn in my hand during autofocus. The Sigma 28-70mm f/2.8 EX DG Lens does not support full-time manual focusing - and the focus ring physically turns during autofocus.

The build here is actually pretty decent, though, and is certainly on the level of the Tamron save that the 28-70DN only has a gasket at the lens mount as opposed to the Tamron’s thorough weather sealing with six internal seal points and a fluorine coating on the front element. The Sigma feels ever-so-slightly nicer in the hand, however, due to slightly more upscale materials on the barrel. The 28-70DN loses a few features relative to the 24-70mm F2.8 DN. Sigma has already released a 14-24mm F2.8 DN lens (my review here), a 24-70mm F2.8 DN lens (my review here), so the logical lens that most have expected is a 70-200mm F2.8 DN lens…but that’s not what we’ve got here. Sigma has instead chosen to release a second standard zoom for Sony FE (full frame E-mount) and Leica L – the Sigma 28-70mm F2.8 DG DN. Sigma asked if I wanted to test a new lens without telling me what it was, so, when the 28-70DN (as we’ll call it for brevity) arrived, my surprised expression looked pretty much like this: I spent my first little while after opening the lens trying to wrap my mind around Sigma’s logic in releasing this particular lens…now. It’s only been 13 months since the release of the Sigma 24-70mm F2.8 DN, a lens I felt was a strong alternative in both performance and price ($1099 USD) to the much more expensive Sony G Master version ($2198 USD). Sigma is obviously banking on successfully addressing two different markets, and there’s no question that they have Tamron’s wildly successful 28-75mm F2.8 RXD in their sites (my review here). The Tamron has been the best selling lens in the world since its release a couple of years ago, and it is different enough in kind from Sigma’s 24-70mm F2.8 DN that Sigma clearly felt a more direct competitor was warranted.
