Mitakon Speedmaster 25mm is the World’s Lightest f/0.95 Lens for Micro Four Thirds

Ultra fast lenses for  Micro Four Thirds cameras like the Panasonic GH4 and the BMPCC for example are highly sought after, but not often very affordable. There are other super fast primes like the Voigtlander Nokton 25mm of f/0.95, which costs about $800 a piece, thus forcing a lot of shooters looking to squeeze that extra stop (and change) of light to resort to using a Speed booster optical adapter and Nikon or EF lenses. The Metabones Speed boosters unfortunately are expensive and for some not an option.

However, there is another super fast option for MFT shooters out there – it’s called the Mitakon Speedmaster 25mm f/0.95. Made by Zhongyi Optics (ZY Optics) the 25mm is the latest addition to the Speedmaster family is a ultra-fast prime lens which provides a 35mm-equivalent focal length of 50mm in the Micro Four Thirds system. A maximum aperture of f/0.95 makes it extremely convenient to shoot at a low light conditions without flash.

What is probably as impressive as the super wide aperture – is the fact that it weighs a mere 0.51 pounds and is just 1.8 inches long. The compact size and fast aperture make it an ideal companion of your camera for everyday shooting in a wide variety of conditions.
