If you were asked to choose a cost-effective zoom lens that could match multiple micro-single cameras at the same time, which one would you nominate? As a professional manufacturer who once produced 135 camera exchange lenses, Sigma's lenses have conquered many photography enthusiasts with their excellent sharpness and high cost performance. I have also introduced Sigma's lenses to you before. One feature of this brand's lenses is that they are heavy, which is called "weight lifting horses". As Sigma's second "Art Zoom" lens designed for micro-single cameras, what are the advantages of Sigma 24-70mm F2.8?

In order to ensure good picture quality from the center to the edge of the lens, Sigma 24-70mm F2.8 incorporates Sigma's excellent optical technology: 6 fluorite-grade low-dispersion lenses, 2 special low-dispersion lenses, 3 aspherical lenses, etc. The NPC nano coating added also greatly improves the performance of anti-glare ghosting. This lens adopts 15 sets of 19 optical structures, with the shortest focus distance of 0.18m, and has very good close-up capabilities.

Another major advantage of this lens is that it matches the commercially available full-frame micro-single cameras and is compatible with many functions of current full-frame micro-single cameras including eye-controlled focus. However, this lens still has the "weight lifting horse" style, with the lens weight of 835g, and it is understandable that the stacking material has enough weight to have such a lens. In terms of protection performance, Sigma 24-70mm F2.8 adopts the same three-proof sealing performance as Sigma 14-24mm F2.8. The lens retains the AF/MF switch, and adds a new AF-L focus lock button that can be customized for multiple functions and a zoom ring lock lever.

has been commented by bloggers. Since its optical path system consists of 15 groups of 19 lenses, it uses multiple FLD low-dispersion lenses and SLD special color lenses, which can effectively eliminate the phase difference and chromatic aberrations that occur during shooting, making the picture more transparent and clean. Some bloggers also commented that this lens is the most versatile hanging lens. However, this lens also has shortcomings. Some bloggers say that this lens will be out of focus on some bodies, which is somewhat "looking at the face". How do you think this lens performs? Do you have any useful lenses that you recommend and share with you? Everyone is welcome to leave comments.
