I think just about everyone in the DSLR community is feeling frustrated that after 4 years of DSLR development, the Sub- $5K camera category is so full of compromises. There's no perfect camera, but the prosumer cameras in the $1.5K and under range seem to be a much better value. As tempting as it may be for a new camera, I will use my current gear until there are better alternatives for a $3-5K investment. None of the manufacturers have demonstrated a clearly definitive camera at this price point. The AF100/101 could have been updated for NAB 2012 but nothing happened. In addition, there have been no clear signs from Panasonic to indicate the M4/3 format for pro-use will be supported. The X-lenses at f2.8 are a step in the right direction, but those lenses at f2.0 would indicate to me that Panasonic is committed to product development for professional use. Olympus designed and produced f2 zoom lenses YEARS AGO. Why hasn't Panasonic?
Perhaps the GH3, the BMD Cinema Camera, the Sony A99 or the Digital Bolex will fulfill the current $3-5K void for filmmakers. But for now, making the most of my GH2 and 60D seems to make the most sense---at least until a manufacturer can offer a product that is clearly worth the significant cost of upgrading.
