Canon has sent out another invite for April 16, 2012. This will be beyond the screening from the other invite.
Could this be the hoped for 4K DSLR Canon has already teased the world with? As some would say, is this what videographers wanted the 5D Mark III to be?
We have heard the 4K DSLR would be announced sooner than later, however it's rumoured availability would be in the distant future.
