Why we love this ?
This is one of our favorite prime lens.  We love this so much because of its low light shooting capability.  It is a 25mm wide angled lens but with such a fast aperture.  We have been using it for a while and love it so much. 
A truly fast and compact prime, the black Speedmaster 25mm f/0.95 Lens from Mitakon Zhongyi is compatible with Micro Four Thirds mirrorless cameras, where it presents a 50mm equivalent focal length. The bright f/0.95 maximum aperture is well-suited to low-light shooting and also offers extensive control over your focus position for shallow depth of field applications. One extra-low dispersion element is incorporated within the lens construction, as well as four extra-high refractive index elements and two high refractive index elements, to limit chromatic aberrations and distortions for a high degree of clarity and sharpness throughout the aperture range. Additionally, optimized lens coatings have been applied to limit lens flare and ghosting.
