Sigma is introducing a new full-frame 28-105mm f2.8 DG DN Art lens for Leica’s L-mount and Sony’s E-mount cameras.
According to Sigma’s announcement for the new optic, this model is designed to cover the range of several commonly used focal lengths including 28mm, 50mm, 85mm and others while maintaining a constant aperture.
This design quality should make the new lens into a versatile and ultimately popular option for Leica and Sony camera owners hoping to save some money via multi-purpose third-party lenses from a brand that’s widely recognized.
Internally, Sigma’s new lens contains 18 elements placed into 13 groups. Among these are two fluorite-like “F” low dispersion (FLD) elements, five aspherical lenses, and one super-low dispersion (SLD) element.
Furthermore, for the sake of field use, the front element of the new 28-105mm F2.8 has an oil and dust-repellant coating, aside from the full-body water and dust resistance that Sigma claims for the lens.
Sigma has made the 28-105mm F2.8 robustly, but it’s also slightly on the heavy side. The L-mount version weighs 996 grams or 35.1 ounces and the E-mount weighs about the same. On the other hand, the versatility of the lens is a major selling point that some photographers might love.
Sigma is positioning the 28-105mm F2.8 as an optic that’s useful for both photographers and videographers.
For the video recording crowd, the manufacturer is touting claims of a High-response Linear Actuator AF motor that delivers noise-free video focus changes and “minimal” focus breathing.
In tests with the lens, the website DPReview stated that its 28-105mm focal length made it unusually versatile for lots of everyday shooting. The site also mentioned the “tactility of the lens”.
Sigma’s own sample images look good too:
Sigma’s 28-105mm F2.8 also comes with an aperture ring that can be switched from click to clickless mode through with a switch and which also has a lockout for keeping it in its auto setting.
Other controls include a zoom lock, a switch for AF/MF and a couple of AFL buttons.
Its hefty weight aside, the new Sigma lens is fairly compact, with a closed length of 15.7 cm or 6.2 inches and a fully extended length of roughly 19.5 cm or 7.7 inches.
The minimum focusing distance of this Sigma lens is a fairly long 40 cm or 15.8 inches and it comes with an 82mm filter size.
Sigma will start shipping the new 28-105mm F2.8 DG DN Art lens for both Sony and Leica mounts as of late September for an asking price of $1,499. You can preorder it now though.
