Hmmm, think I'll stick with my Olympus 12mm f/2.
The Oly 17mm f/1.8 lacks the Voigtländer's distinctive optical look (and speed) but makes for a more balanced package overall (see attached photo). I regret I've had so little time to give my BMPCC the workout it deserves. I bought the Voigtländer set specifically with video in mind too, yet I've used them only for stills.
Time to get the hell outta Michigan and go somewhere warm & pretty for awhile.
