Sigma 24-70mm F2.8 DG DN Art Sony E Mount 578965

Product Information

there is always the possibility that a DSLR body might not support a (likely older) third party lens.

What photographers demand from the 24-70mm F2.8 specification is much more than outstanding image quality. They want all the features that make this a go-to lens for a wide range of photographic opportunities, including optical design ideal for the latest ultra-high-megapixel digital cameras, hypersonic motor (HSM) for high-speed autofocus, optical stabilizer (OS) with powerful stabilization effect, dust- and splash-proof mount with rubber sealing, and a metal barrel for a stable, rigid feel. Combine those types of motors with a light focus group and you get truly great speed. And if you desire optical perfection "just" use two independent focus groups like many modern high end mirrorless lenses. Sigma Announces New 24-70mm F2.8 DG DN Art Zoom Lens for Full Frame Mirrorless Cameras; Available in Sony E-mount and L-mount

Black Friday

Launch of the 24-70mm F2.8 DG DN Art Zoom lens for full frame mirrorless cameras, leveraging the top-level Art zoom performance, featuring: This is my first lens after my initial kit lens, of course it is a massive difference but that don't mean I have to kiss it's ass, there are negatives to this lens too.

There is also the risk of a problem that results in the lens and body manufacturers directing blame at each other.At 50mm focal length the new Sigma is softer across the sensor than the other three lenses. Stopping down to f4.0 helps lift the APS-C image-circle visibly but the FF-corner remains pretty soft until f8.0. Filter-thread: 82mm just like the others except for the Tamron which uses cheaper 67mm filters. [0]

Had this lens four years now and got it to upgrade the superb DA SMC 18-55 3.5-4.5 that came with my now dead K100D. This was my first non kit walk around lens and it's attatched to the camera unless I need longer reach. It's what you expect from EX Glass, it's an absolute tank. HSM is snappy enough for my needs (Portrait and kids photography and some landscape. I've used it for astro and it's done the job nicely too) The only real downside is that it can be a touch soft at 2.8 to 3.5 but I've used it at 3.5 with good enough results on print up to 10x8s. It's bokeh could be better but I have realistically nothing to complain about. I was considering a 16-50 2.8 Pentax * but I decided against it because this came up used from a reputable dealer at a few hundred pounds sterling cheaper. If I didn't have this tomorrow I'd replace it in kind. Sony has the FE 24-70mm f2.8 GM from 2016 (1860 EUR / 2200 USD). It is just a little longer/heavier than the Sigma and offers similar features. See my Sony FE 24-70mm f2.8 GM review where the lens earned a recommendation. Internally, Sigma says they’ve updated the optical construction to meet the demands of ultra-high-megapixel cameras. It has 19 elements arranged in 14 groups, with 3 low-dispersion elements to reduce chromatic aberration. In addition, the large-diameter zoom features an image stabilizer unit. Sigma is also keen to point out that it has adopted high-grade aspherical lens elements to reduce aberrations, while at the same time paying close attention to the shape of the bokeh. Essentially the Leica 24-70mm f2.8 ASPH SL is the Sigma 24-70mm f2.8 DG DN Art internally. You can read our review of the Sigma here. Externally, the Leica uses a metal body with rubberized rings.

As a newer lens, we expected the Sony to dominate in terms of image sharpness, and we have to admit it is more consistent across the image at wider apertures. Nevertheless the older Sigma 24–70 Art holds its own in this regard. The Sigma 24–70mm F2.8 DG DN Art's rivals differ depending upon whether you're an E-mount or L-mount shooter. For E-mount, there's only one direct rival but several other lenses which are at least in the same ballpark. On the L-mount, though, there are two direct rivals and one more which is fairly close in its focal range. Unfortunately the Sigma can't compete with the G Master II when it comes to autofocus performance. Although the Sigma is no slouch in this regard, the Sony delivers faster and smoother focusing thanks to its four linear XD motors. Above: Sony FE 24-70mm f2.8 GM at 70mm, f2.8; 100% crops from the FF-corner at f2.8 (left), f4.0 (middle), f5.6 (right) A tougher choice is whether to go for the Sigma or the slightly less expensive Tamron G2 lens. The Tamron has more extensive weather-seals and a slightly more effective stabilizer, but the Sigma edges ahead for image quality, especially in terms of sharpness at the long end of the zoom range.
