Samyang (aka Rokinon) just posted a teaser on their Facebook page, saying:
In this Summer, the five Samyang Blockbuster series will blow your mind away!
5 NEW Samyang Lenses will be released on every Monday for the next five weeks.
So far no idea what kind of lenses they are going to announce. However, it’s a pretty safe bet that they will come with Canon mount (among others). Stay tuned.[via 43 Rumors]
