Zeiss Otus 100mm F1.4 Costs as Much as Three Sigma Lenses

There is absolutely no doubt about the quality of Zeiss lenses. The Zeiss Otus line has continually wowed people with both their performance, and their astronomical prices, but so have Sigma lenses with their image quality, and much more palatable price points. With the news that a new Zeiss Otus 100mm f1.4 has just been announced, one has to wonder just how much longer Zeiss will be able to compete with offerings from Sigma that do just as good a job as lenses that cost three times as much.
