Sigma recently announced on its official YouTube channel that it will hold a new product launch event at 9 a.m. on February 21, and the most likely new product to come out is speculated to be the long-awaited 500mm F56 dg dn os sports and 15mm f14 dg dn diagonal fisheye｜art。
According to reliable foreign sources, the Sigma 500mm F5The 6 dg dn os sports would be one that weighs less than 1The 5kg featherweight supertelephoto prime lens will be the lightest in its class; At the same time, when shooting with the Sony A1, there will be an unexpected focusing speed performance.

As for the convenience of the price, it is rumored that the ** of the mirror will be slightly less than $3,000.
Just by looking at the specifications, you know that it is 15mm f1The 4 DG DN Diagonal Fisheye Art is a diagonal fisheye lens that has never been seen before, after all, whether it is mirrorless or in the past DSLR era, no fisheye lens has ever achieved such a large aperture, so it is destined for 15mm f1The 4 DG DN Diagonal Fisheye Art is sure to leave a mark in the history of photography. Some people may say that Olympus has launched an 8mm F1 before8 Fisheye Pro lens, but it's a 4 3-frame fisheye lens, which translates to 35mm equivalent to 16mm f36. Neither the angle of view nor the aperture can be compared with the sigma15mm f14 dg dn diagonal fisheye art.
Although there has never been a fisheye lens with such a large aperture in the past, we can still speculate that the Sigma 15mm f/1The size of the 4 dg dn diagonal fisheye art should not be small, after all, the maximum aperture reaches f14. Therefore, the volume of the lens can be expected to be huge, but to what extent? 2 21 will be revealed. In addition, it is also due to the aperture of this fisheye lens of f14, so I believe that it will be able to bring some new shooting applications and experiences, such as astrophotography, and even underwater photography, etc., let's look forward to the 2 21 press conference!
