Cannon recommends BB after a long period of not using the camera or after shooting in various ISO settings. I have a C300 and do BB after each shoot and so far no issues. I also have a Panny 500 which I haven't shot with in about a week and did a shoot today and the BB was very high so I made need to make an effort in doing this more often than not.

I BB at the beginning of every shoot and every time I change ISO. But I don't take the lens off, I just leave it there with the cap on.

Well, here's the thing. I've shot the hell out of my C100 over the last month, in all kinds of condition and with wide ranging ISO settings, and haven't once set the BB. So as a test, I just set up a shot with some white, some black, some other stuff, locked off the camera, and squeezed off a shot. Then I removed the lens, put on the body cap, black balanced, put the lens back on, and shot it again. All levels, to my eye, are identical to the first shot. Mind you, I didn't check both shots on a scope, but I doubt there'd be much difference. So I guess to restate my original question, under what conditions does setting the black balance become really important?

If you are going to shoot at higher iso settings I suggest you abb before you shoot to eliminate any possibility of dead pixels showing up on your clips. It is very difficult if not impossible to see dead pixels unless you are using a very good monitor. You may never see them until you get the shot on a big high resolution screen. It is a habit of mine to run bars and playback and do an abb before each shoot.

I use the C300 and use all kinds of high ISOs. I am not sure if black balancing can be done with the lens attached to the camera and lens cap on. It is a pain removing the lens and putting the body cap on and then black balancing it in the field. I am in incredibly dusty environments. However, I do it when I change these high ISOs. It appears to me that there is a difference if I don't do the black balance. I remember one day I didn't do the black balance and the shot of leopard was incredibly noisy. However, I have to scientifically do an experiment to conclusively say how much of a difference it is.

A black balance does the same thing for blacks that a white balance does for whites. Also a Black balance can possibly mask any dead or burned pixels that may show up from time to time.
This should always be done after flying with the camera as the upper atmosphere can cause damage to pixels.
One reason to always BB the camera in a controlled environment before you go out in the dusty world. Don't see why you could not BB the camera with a lens on as long as you stop down the camera and add a cap. It is just looking for a black reference.
