I was about to buy a good, used, low hours AF100 with Voigtlander 25mm lens and a host of accessories, but the new Blackmagic has me hesitating. This would be my first video camera purchase and I'm unsure if the AF100 is about to be eclipsed. It's not as if I have a host of existing lenses that help steer this decision. They're a purchase I still have to make. Is the 2.5k 12 bit spec on the BMD a big advantage? Im dubious about its smaller sensor, only 61% of the area of the 4/3 sensor. Will that significantly affect DOF? I like the software and thunderbolt connection in the BMD but the limited range of frame rates is a negative. What are the key drivers in a decision like this? The used deal on th AF is priced right but I honestly don't know which way to go.
