Cinima5D did a short documentary using SLR Magic MicroPrime Cine X-Mount lenses that you can watch above called “A Place for Grace.” they also reviewed the lenses and there is an excerpt from their conclusion below.
“SLR Magic’s MicroPrime Cine X-Mount lenses are very easy to handle and work with, and build-quality is impressive. In terms of picture quality: if you are looking for optical perfection or absolute sharpness, look elsewhere, yet if you are after a unique look and strong lens characteristics, these lenses certainly tick the box! For their price point, they are good value for money, BUT one has to remember that working with wide open aperture will result in a very noticeable deterioration of picture quality. If the maximum aperture of T4.0 is fine for most of the work you do, then those lenses might be right for you.”
