Dafilman21 I can't help but asking. How come you are looking to buy a c100? I see you have an A7s and bmpcc, what needs are you looking for the c100 fill?
Sparkle Motion, in general:
-speedbooster not 100% dependable
-color
-dynamic range
-12 min limit
-better compression and smaller file sizes for projects
I sent a pm to you Sparkle, Also @lunknown the A7's does not have the 12 min recording limit, I believe it is either 25 or 29 mins. Also the A7's shoots AVCHD just like the C100 so I would say the compression is the same. And DR wise in Slog I believe the A7's comes out ahead of the C100. So those reasons you mentioned are not why I was looking for a C100. I needed one for a client that I will be shooting with for most of the summer. I also wanted a proper smaller video camera that shot to a easily up-loadable codec. The A7's is a great lil camera for what it can do, I just needed to add another more versatile tool.
