Just started shooting on a Viltrox 27mm f1.2.

Here are pros and cons.

Pros:

  • sharp all around from 1.2 all the way to f11 before defraction takes over
  • no barrel or pin cushion distortion
  • no chromatic abberation

Cons:

  • heavy lens especially if fitted on a smaller camera
  • vignetting at f1.2. it goes away at around f4.
  • little bit of flare when shot directly at a light

Otherwise, fantastic lens with super sharp results.
