I'm extremely disappointed by this announcement. These are the features many of us wanted, but they should just be part of the evolution of DSLR. Canon is forcefully separating camps into (likely highly expensive line of equipment) which really goes directly AGAINST the reason DSLR video had such widespread success in the first place. Pro-equipment being affordable (or at least with-in reach) in the hands of the masses was largely the point and this seems to miss that entirely.
They just fractured a business model that was working perfectly for them. I fear they have done something quite so very stupid. If this doesn't interfere with the natural progression DSLR video was on, then fine, no harm no foul, but only time will tell, and I've smelled this smell before. It's a distinct smell.
I'm not at all impressed, the 5D Mark III and the 7D Mark II (and probably even the 1DX) should be/have been launched with 4k capability, as it's quite essentially useful for editing 1080p format. It allows the editor the ability to re-crop and or pan the image and as well use digital image stabilization and then have some room around the frame to crop after stabilizing the content. Similarly, higher than needed framerates, etc. etc., all things Canon could have been working on and figuring out for our replacement models instead of this....
The sensors on DSLR are already capable of 4k pixel wise, and so are the lenses. Regardless, I'm going to have to simply ignore all the new products, let Hollywood blow their wad on it, I just hope it doesn't interfere with one of the main reasons I got into Canon DSLR video in the first place. I'm not happy or excited, in fact I feel kind of used and stupid for playing along. Time will tell, but if they don't eventually release the features we need on the budgets we have someone else will, and then where will they be?
p.s. I am not going to waste precious budget splitting my photography and film needs across multiple product lines, why do you think I got a DSLR? Oh and, I'm already sick of the new marketing term "EOS Movie".
This has been your negatively honest announcement for the day, enjoy your breakfast.
