I know the C100 (Mk1) and the new Rebel SL3 are two very different animals, but fact of the matter is, I've barely used my C100 over the past 18 months, and I'd like to have something with a smaller form factor that I can still use all my Canon glass on, mostly for still photography but also for limited personal video use. Professionally, I've been using cameras that either my DPs have brought to a shoot (lots of Panasonic Varicam and RED work), and I find the old C100 is just collecting dust and slowly losing value. So my question is, when I sell my old C100/Ninja package, what will I be losing from my current setup when switching to the SL3? ND filters and on-board audio immediately come to mind, but it looks like I'll also be gaining 4k and time-lapse capability with the SL3, cropped though it may be. Comments/input are appreciated!
