The zoom ring located at the back of the lens turns very smoothly and the zoom lock can come in very handy to stop zoom creep at 24mm. The only missed shots occurred when the lens was in near darkness or too close to a subject to focus. With a reasonable amount of light, the Sigma is fast to lock onto focus throughout the focal range. Lastly, the Sigma 24-70mm f/2.8 DG DN Art lens has a 82mm filter thread, fitting the included petal shaped lens hood very tightly. Also of note, the lens isn’t fully weather-sealed, but it does have a rubber grommet around the lens mount to keep out dust and moisture. The focus lock button can also be assigned to various camera settings, such as focus lock. Unlocking the zoom can also be done by turning the zoom ring. The two switches include one for AF/MF and a zoom lock switch keeping the lens barrel in place at 24mm. The lens barrel has two switches and a focus lock button. There’s also no DOF markings on the lens barrel, which is usual for mirrorless lenses. The focus ring itself is extremely smooth in its workings, with a large turning circle for very precise manual focusing. A stepping AF motor has been used for autofocusing, which has a manual focus override. There is no image stabilization on this lens, which means it’s wholly down to the camera body for anti-shake duties. There’s also an 11-blade rounded diaphragm, which should in theory produce more rounded bokeh balls than a nine-blade version. A Super Multi-Layer and Nano Porous Coatings have been applied to reduce aberration, such as reflections, flaring, and ghosting.Ĭlose focusing distance is reasonably good at 18cm, with a maximum magnification of 0.34x. The optics of the lens are arranged with 19 elements in 15 groups, including eight dispersion (Six F Low Dispersion (FLD) and two Special Low Dispersion (SLD)) and three aspherical elements. Not overtly heavy, but still needing an ample hand hold on a mirrorless body. The lens is also verging on the light-heavyweight class at 827g. It’s also reasonably compact at 88 x 125mm, with an extending lens barrel when zoomed in. ![]() Designįirst impressions of the lens are that it follows the ‘Art’ series with its simplistic layout. A Canon and Nikon version is hopefully in the works, but for now, we will check out how this lens operates on a Sony a7R II body. This makes it a different proposition from the DSLR version from 2017, available for Canon and Nikon mounts, and also featured image stabilization.Īs the new lens is built specifically for the mirrorless format, it uses focus by wire and a dedicated button that can be set for various camera parameters. The Sigma is one of three lenses available for the full-frame mirrorless Sony E and Leica L mounts. ![]() In this regard, we are looking more closely at the Sigma 24-70mm f/2.8 DG DN Art lens. In my case, it was the Canon L-series version which covered the most usable focal lengths and served me extremely well from landscapes to wedding photography. A little weird having emotional attachment to a focal length range, but this lens was my first, top quality zoom lens back in the day. I have to admit, I have a soft spot for the 24-70mm zoom lens.
