他沒有什模都贏,直接看summary就好. 不過倒是價格和c/p值是真的贏.問題是好鏡頭又不是只看銳利度!
Summary
The new Sigma 24mm f/1.4 Art lens does, indeed, out resolve the offerings from the major manufacturers, at least in the center of the image. At the edges, though, the advantage disappears. More importantly with any 24mm f/1.4 lens, try as you will, unless you really stop the lens way down you aren’t going to get a flat field of focus. And if you are going to stop the lens way down, why invest all the extra money for a wider aperture lens?
That doesn’t make these bad lenses. There are clearly some types of photography that this focal length is invaluable for, and in that case you just learn to work around the shortcomings. In many cases, though, the old rule that “the best 24mm f/1.4 is a 35mm f/1.4 and a few steps backwards” is often true.
以上總結好像沒有提到這些事吧!
銳利度是基本的，有用過Samyang/Rokinon 24mm F1.4就知道，最大光圈的基本銳利度沒有，真的有點白買F1.4的感覺。
