pro video work requires lot of creativity with shallow DOF. if i were a pro videographer, i would always prefer a 5dmk2 or 5dmk3 over a aps-c body. plus pro videographers often use their gear roughly and in different outdoor conditions (drizzle, dust, harsh heat/cold). a weather shielded tough body like 5dmk2/3 would be always preferable over a aps-c 60d or 550d or 650d. 7d also can be another option for pro work.
coming back to 650d, i find it too close to 60d in terms of features. both r 18mp, all cross 9pt, same screen resolution, same metering, almost same video, almost same burst rate etc, no weather shielding, no microadjustment, no mag-alloy body etc etc. then i why will somebody buy 60d if he can get a 650d in lower price? very strange move from canon.
cheers!
