Olympus announced its first 25mm prime lenses for Micro Four Thirds mirrorless cameras back in 2014 with the lightweight 25mm ƒ/1.8 lens, a classic 50mm (eq.) focal length with a decently bright ƒ/1.8 aperture. But, if that isn't fast enough for you though, a new option is now available -- the 25mm ƒ/1.2 Pro M.Zuiko Digital.
The 25mm ƒ/1.2 Pro, one of the newest additions to their growing professional-grade Zuiko Pro line, offers the fastest aperture available in any Olympus lens so far. However, at a sticker price of USD$1,199, it's definitely available at a premium. The price tag is justified by the impressive amount of glass making up the lens - 19 elements in 14 groups, including 1 aspherical, 1 SED, 2 ED, 1 E-HR, and 3 HR elements.
