Since CES 2018, the largest consumer electronics fair, is taking place at the moment, I was eager to learn more about the mystery 50mm lens shown on Sigma’s current roadmap. In case you are interested you can read more about it here. The way it looks like at the moment, Sigma wants to announce all of its hot stuff during the CP+ 2018 fair, which is going to take place at the end of February.
No matter, with a couple of leaks hi-lows-note, a Japanese photo tech blog, is making it impossible to get bored, even despite the lack of official announcements. 🙂
The first patent shows an unusual lens, an 18-50mm f/2.8 (Link). You are no doubt asking yourselves what is so unusual about a fast standard zoom lens. Well, this one is non- interchangeable and as such designed with a compact camera in mind. What do you think, is Sigma working on a DP camera with a zoom lens? The following image shows the rather complex design of the lens, which consists of 18 elements.
The other two lenses are super-fast prime lenses for micro 4/3 (Link): a 14mm f/1.2 and a 35mm f/1.2. Whether these two lenses are indeed designed solely for micro 4/3, is impossible to say going by google translate alone. At any rate, I would find it very surprising, should that turn out to be true. After all, all Sigma lenses for mirrorless cameras are designed for APS-C. Otherwise it would be impossible for Sigma to offer versions for the Sony E mount. In any case these two lenses also have complex designs consisting of 18 elements. The fact that all three lenses consist of 18 elements is surely sheer coincidence. 🙂
