Sigma Finally Gets Onboard with Micro Four Thirds Lenses. 43Rumors site just posted a patent by Sigma showing a new Micro Four Thirds lens they are at least thinking about. The patent is for a Sigma 35mm F/2. Remember you have to multiply all MFT lenses by two to get the equivalent length of traditional full frame cameras. With that in mind it will make this lens a 70mm F/2. An added bonus is it will be part of the so-called ART line of lenses which are a series of super high quality optics that score as high as some Leica and Zeiss lenses, typically the finest lenses you can buy. Very nice!

Sigma has had other lenses that fit the MFT cameras but they have all been much larger AP-C lenses that they added an MFT mount to. The downside to that method of making MFT lenses is the fact the MFT sensor does not require the larger lenses of the AP-C bodies. Thus, with Sigma building specifically for MFT, we will have a very small and compact 70mm F/2 lens that gives us the size and weight many of us desire in the MFT line of cameras and lenses. Can’t wait to see what else Sigma may be bringing to the MFT world.
