First questions cross my mind are this:
Canon EOS 7D Mark II vs Panasonic GH4 vs Blackmagic Production Camera 4K
Which one to buy? According to some internet sources Canon will announce new camera: Canon EOS 7D Mark II in March 2014. New canon DSLR beast will have 20MP or 24MP sensor with Dual Pixel CMOS AF. Camera will not have sensor like it’s predecessor. Auto-Focus system will be similar to the EOS 5D Mark III and will have 61 points auto-focus range. Really high frame rate per second, 10-12 fps. Dual Digic V+ processor. New canon DSLR will have some innovative video features. Price will be very similar to Panasonic GH4. Around 2000$. Very good ISO performance. Quiet shutter mode.
