From the world of interesting concepts
I received an email from someone claiming Canon has video dslr lenses on the horizon. How many? They didn't say.
The concept is this; the lenses will have the manual controls a lot of videographers want… i.e. an aperture ring.
Other than being a cash grab, I'm not sure why Canon would do it this way over a firmware update. Perhaps an adaptor with an aperture ring? A nice $200 accessory Canon can bilk you for!
I'm filing this under “unlikely”.
This IS a rumors site. I'm going to give you most of the information I get. With the new ratings system, it's up to you to decide how viable it is.
