More on lenses

In response to yesterday's comments about the new Canon 16-35mm f/4 lens, reader Paul Antico writes:

I read your lens article. I have like 8 or 9 lenses ranging from cheap (but excellent) rokinons to the canon f2.8 70-200 is II which cost like $2400.

What lens do I use for video most constantly on my video cameras? The 24-105 f4L IS.  For video usually f4 or F 5.6 is where I want to be for most shots anyway to ease focus and allow a bit of depth. The lens looks nice, is relatively rugged, and has decent IS. It's a great all around stills lens too. And the c300/100 and my 5D3 have more than enough low light ability to compensate for the stop difference over 2.8.

Only on set up shots or interviews do I really use anything else actually. For quick setups and being mobile or running around, it wins every single time for quality and a great selection of useful focal lengths. (I use the 17-55 IS on the c100 too but it's a horrible lens body with nice glass inside).

Paul also passed along this notice from Canon, adding that's he's never seen his camera display the wrong f/stop.
