About this deal

It will also work with APS-C sensor cameras with an effective increase in focal length to 42-105mm due to the crop factor.

Weighing in at just 470 grams and measuring nearly 10.35cm in length, the Sigma 28-70mm F2.8 DG DN Contemporary is a very light and compact lens given its versatile focal range. Sigma’s 24-70mm f/2.8 Art lens for Canon and Nikon full-frame DSLRs has made quite a name for itself. Following in its footsteps, the ‘DN’ edition is a completely new lens for mirrorless cameras, so far available in Sony FE as well as Leica L-mount options. High-grade optics include no less than six FLD (‘Fluorite’ Low Dispersion) and two SLD (Special Low Dispersion) elements. Top-notch construction includes comprehensive weather-seals and a super-fast, essentially silent stepping motor autofocus system. Barrel distortion at 24mm and vignetting at f/2.8 are rather noticeable when uncorrected in-camera but overall handling, performance and image quality are excellent, and it’s ultra-sharp. At half the price of Panasonic’s 24-70mm f/2.8 lens, the Sigma is a steal at the price. The Sigma 28-70mm for Sony lens features a rounded 9 blade diaphragm which creates an attractive blur to the out of focus areas of the image. The Sigma 20mm F2 DG DN | C joins a growing range of fairly fast primes for Sony E-mount and Leica L-mount cameras in Sigma’s I-series range, which includes the 35mm F2 DG DN | Cand 65mm F2 DG DN | C. There are also 24mm F2 and 45mm F2.8 options in the line-up. The look and feel are virtually identical in each case, with the same ‘Contemporary’ design ethos seeking to deliver excellent performance from a compact and lightweight build.True to the Contemporary line’s core concept, the 28-70mm F2.8 DG DN was developed to offer the right balance of performance and portability. It has been designed to deliver outstanding image quality that rivals SIGMA’s Art line lenses in a body light enough for day-to-day use.

Sigma 28-70mm f2.8 DG DN Contemporary Lens (Panasonic L Mount)

If you thought that ‘compact system cameras’ were relatively small and lightweight, Panasonic’s S series bodies will make you think again, and this lens is frankly enormous for a 50mm prime, weighing in at almost a kilogram. Even so, handling is refined with tactile aperture and focus rings, the latter having Panasonic’s usual push-pull mechanism for swapping between autofocus and manual focus. Autofocus itself is super-fast and virtually silent, powered by dual linear and stepping motors. The optical path includes two aspherical elements and three extra-low dispersion elements, along with a particularly well-rounded 11-blade diaphragm. Image quality is simply spectacular in all respects. Even so, this hefty lens comes with a similarly weighty price tag. The Sigma lens weighs about 100 grams less than the Leica version, and while this isn’t really a significant difference, it does at least seem noticeable when hand-holding the camera, since the system is just that much less front-heavy. As for the comfort and ergonomics, both feel very much the same. Sleek, responsive, smooth to the touch, with both versions of the lenses focus and zoom rings responding at nearly identical speeds. Next here’s the view at 50mm, roughly mid-way through the range, and with the aperture wide-open to f2.8. Yes, I definitely remember you telling me that. A foveon sensor would be an absolute game changer I think. Not only are Sigma lenses superb but imagine being able to use a camera like that with the Panasonic and Leica lenses as well? As for the autofocus, the 28-70mm f2.8 DG DN Contemporary lens uses a stepping motor that is definitely responsive. It’s plenty fast, and accurate. It’s also near silent. The camera usually plays a part in autofocus performance, and as I mentioned earlier, I was testing this lens with both the S1, and the fp L. It works great on both cameras.A little color fringing can be apparent towards the edges and corners of the image frame at shorter focal lengths of 28-35mm, though it reduces to unnoticeable levels once you zoom in to 50mm and beyond. unhappymeal - "until April of last year (or was it 2019?), Sony Cameras was a part of the same group as their Semiconductor group"
