We did note some field curvature for macro shooting, which leads to rather soft corners, but the 24–70mm F2. When looking more closely at the results, we can see that Sigma has gone to great lengths to achieve a more consistent level of sharpness, particularly wide-open at f/2. OS is also useful for stabilizing the viewfinder, aiding in optimal composition, and for stabilizing video recording, creating a handheld result that is much more

All Sigma’s manufacturing – right down to moulds and parts – with a few exceptions, are carried out under a single integrated production system, entirely in Japan. For the latter it offers full-frame-equivalent focal lengths from 36mm to 105mm, with corresponding impact to the effective aperture. It is designed for full-frame mirrorless cameras and available in the native Sony E and Leica L mounts, the latter working on Leica, Panasonic and Sigma L-mount bodies. The Tamron is quite similar to the Sigma while the other lenses in this comparison produce their largest magnification of around 1:4 at 70mm focal length. While the 1/15 second shutter speed used for that capture at 27mm may not sound amazing, I was in an unstable position, balanced on uneven rocks while trying to frame the scene through an opening in the trees.Peak Design's newest Camera Cubes allow you to turn any pack or bag into a camera-carrying accessory. Despite a somewhat plastic toy-like feeling to the lens, though, it holds up to rugged use and all parts zoom and turn confidently.

Remove the lens hood from the camera body before use when photographing at the minimum focusing distance at the wide-angle end. From our tests, it is clear Sigma prioritized sharpness across the frame (that is, the image field) at each focal length and aperture over outright sharpness, something that we’re seeing more frequently with modern designs. lens’s overall score of 31 on the Nikon D810 puts it 5 points behind the maker’s 24-35mm f/2, which is a noticeable margin. There is no focus variation whether the lens focuses from a closer distance or from infinity and I didn’t detect any hunting.

SIGMA is organizing all its interchangeable lenses into three product lines: Contemporary, Art, and Sports, each with a distinctive concept. Lens profile: The lens comes with a lens profile for vignette-, CA- and distortion-compensation which can be controlled from the camera. It has 19 elements arranged in 14 groups, with 3 low-dispersion elements to reduce chromatic aberration.

Sigma 24-70mm f/2.8 AF DG DN Art review - Digital Camera World

Sigma USA's 4-year warranty is far superior to Canon's standard 1 year warranty (Sigma's international warranty is also 1 year). I'm certain that this image and the many others I captured on this hike would not have been sharp without the aid of OS (or a tripod). But they did state they replaced them and there are multiple reports of people claiming sigma told them there were initial problems with the seals. Focal length is especially important in that it drives focus distance choices, which in turn determine perspective for the desired composition.He is Digital Camera World's principal lens reviewer – and has tested more primes and zooms than most people have had hot dinners! In our our test of the Canon-mount version, you’ll get an idea of how the Sigma Art lens fares against the Tamron and Canon models. The ‘DN’ edition of Sigma’s 24-70mm Art lens is the same width but slightly longer than the SLR equivalent.

When using a circular polarizer filter with narrow apertures (typical for landscapes and cityscapes), OS can be helpful even under a full sun. Another big wide aperture advantage is the shallow depth of field available at the widest aperture, enabling distracting background details to be rendered out of focus if desired, isolating the subject through the use of shallow depth of field. Yes, the Sony GM II is a bit better, but it's not like 2-times or 200% better than the Sigma ART, but costs a lot more. Overall, it's a superb performance in all respects except for its weird mechanical vignetting when shooting wide-open. With an overall score of 31 on a Nikon D810 body — one of the best performing cameras available (but now superseded by the D850), theSigma 24-70mm f/2.

I attempted to shoot a track meet with this lens, but few in-action subjects were rendered in-focus. Contrast is well maintained across the image and the lens largely avoids washed out areas of the image when shooting at bright sources of light. There is also the risk of a problem that results in the lens and body manufacturers directing blame at each other. To ensure outstanding image quality from the center to the edges of the photograph, the optical system minimizes coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected by adjusting the aperture.
