1/8/2024 0 Comments Sigma 24 70 2.8When I did my focus pull test and tried to pick up sound with the on-board microphone, there was just nothing to hear. The lens simply gets to where it needs to go silently and without fuss. That remains the case here, and, like the build, I have much more good than bad to mention.įirst of all, autofocus was fast in all tested situations. The focus motors are quick, quiet, and smooth. ![]() Sigma’s “made-for-mirrorless” lenses have all shown very positive autofocus performance. There is very little “extra” about the GM lens compared to the 24-70DN. It is a beautifully made, pro-grade lens that feels very quality in the hands. Minor complaints aside, however, the lens handles really well. What’s odd is that they turn in opposite directions, too, with the Tamron turning the same direction as the Sony zooms I’ve tested and the Sigma turning in the opposite direction. It is closest to the front of the lens while the zoom ring is closest to the lens mount. It is worth noting that the focus ring is in the opposite position from the Tamron. When input is detected the active focus area will automatically magnify in the viewfinder or LCD screen and an on-screen distance scale will appear. This method has a little less tactile response but Sigma has done a pretty fair job of giving a smooth, evenly damped focus experience. ![]() The focus ring has thick ribs in a rubberized finish, and is (like all lenses actually designed for mirrorless) a “focus-by-wire” focus ring where input on the focus ring is routed through the focus motor. There is no tendency towards zoom creep, but the lock does help when hiking with the lens to prevent rubbing on the focus ring while moving which might cause it to zoom out. While researching the 24-70DN during my review, I came across this language on Sigma’s website: “ By exerting superiority in mirrorless camera-dedicated designs, the lens size and weight are successfully reduced…” I’m going to have to give them a Pinocchio or two on this, as that’s only partially true, and even the partial truth isn’t the whole truth. Thanks to Sigma Canada for the loaner test lens.įollow Me Patreon | My Newsletter | Instagram | Facebook | Twitter | Flickr | 500px Sigma 24-70DN Build and Handling I’ve reviewed the 24-70mm DN on my Sony a7RIII and Sony a9 bodies. If you would like to watch the review, you can choose either the long format or quick format review videos: Very possibly, though the answer is a little more nuanced than that. So is the Sigma the lens to buy in the category? The Tamron is available for $879 while the Sigma costs $1099 (in the US Market), which is obviously a much smaller gap than comparing a $879 lens to a $2198 one. ![]() At the same time, however, some of the same arguments for choosing the Tamron over the GM lens remain true with the Sigma (size, weight), though the biggest one (price) is much less true. In many ways the new Sigma 24-70mm F2.8 DN ART becomes a more direct competitor to the very expensive Sony FE 24-70mm F2.8 G Master lens due to having a more similar focal length, maximum aperture, optical performance, and feature set than the extremely popular Tamron 28-75mm F2.8.
