Irix 11mm f/4 video review
The Irix 11mm f/4, manufactured by TH Swiss and not shipping yet, is a highly anticipated lens. Christopher Frost Photography posted a pretty informative, 10 minutes video-review of the Firefly version of the Irix 11mm f/4 (the other, more rugged one is Blackstone). He used a Canon EOS 6D and an EOS M3 to test the Irix 11mm f/4.
