Sigma 12-24mm II
适马在这款镜头上堆了：
四片 非球面镜片，其中包括三片玻璃铸造非球以及一片树脂混合非球
一片 SLD “特种低色散”镜片
四片 FLD “类萤石低色散”镜片，适马声称其“性能等同萤石”
堆了这么多猛料，LensTip 评测结果是这样的：
"The official decency level is reached nowhere, even after stopping down. Taking into account the price of the Sigma 12-24 mm II there are too many average or weak results here."
"The Sigma 12-24 mm is undoubtedly a unique lens; if you need such wide angles of view and, at the same time, if you want to avoid a „fisheye” type of instrument you will have no choice. The problem is that currently for such a price you could and should expect more. Nowadays even plastic kit lenses have to be sharp. What could have been tolerated ten years ago is unacceptable today. Although the Sigma improved its performance, compared to its predecessor, it seems the improvement wasn’t as significant as you would wish for."
我仿佛又看见了“国砖”。。。。。。。
