I have been using the canon dslrs for broadcast television. Strictly for local commercials. We mainly use them because they are quick easy to set up can use multiple cameras at once all on a low budget. They give a nice shallow DOF something missing in a lot of local commercials in my area. Our footage continues to stand out and our clients love us because we aren't renting any equipment out. We mainly use the new 5D Mark iii, but have used all of the video equipped canon dslr's and have recently used the panasonic gh2. I see us upgrading to the new Black Magic Cinema Camera, but for now the 5D's are here to stay!
