Hate to say this but the more i read about this camera the more i'm interested in it.
Sure it has AVCHD, only has HDMI out, 4.2.2 colour, only EF mount, 24,25,30fps and for some ungodly reason 60i.
It still makes me want to take it out and have a shoot with it. Sure i love my 60D and 5D2+3 but i would also like something that feels more like a video camera while ergonomically feels like a DSLR.
DSLR shooters currently don't have clean HDMI out (on Canon) so this camera has a welcome change.
Headphone monitoring (check), XLR inputs (check), reduced Moire and Aliasing (check), no more 12min limit on shooting (check). Theres 4 good reasons to buy one right there.
Sure its not as great as the C300 or C500 but then again its like comparing a 450D to a 1DX and complaining about the burst rate or lack of video.
Each camera has its place and this looks like it could make video in a DSLR a secondary feature, to the joy of sooooooooooooo many photographers on here that hate that the 5D2 shot video at all.
I cant wait to get my hands on one and see what it can do.
