Regarding the FP vs S1... I have a buddy that's shoots Alexa regularly and we've been pixel peeping the S1 a lot. He's pretty impressed with the S1 and claims it's "like 95% of an Alexa". The internal 10-bit files are great and flexible, as long as they're not terribly underexposed. You really have to do something crazy for the image to fall apart. The FP looks fantastic as an idea (their video promo is mind-blowing), but it seems WAY overpriced for the amount of hassle that the full DNG will be. When I shot raw on my Blackmagic, I used SlimRaw to convert my full DNGs to 7:1 compressed, but that got real old, real fast. Never again will I bother with full DNG sequences. Unless Sigma prices the FP to sell like cookies, like BM did with the original Pocket, then I'll likely pass on the FP.
