Walking around with camera on ... bad for it?

I've noticed when I walk around with my 40D (especially on a jolty stroll downhill) that the mechanics inside the lens move around a bit. Is this harmful to it? Do you guys usually turn the camera off when you're not using it and walk around?

Mine stays on when in the field. Just set the standby mode to a shorter time if its a concern.

The mechanics in the lens move around a bit?

Are you saying theyre just freely moving? Or you keep accidentally bumping the shutter button to make it AF or engage IS?...

Mine goes into standby after 1 min, and i usually never touch the on/off switch.

I'm fine walking or even jogging with a camera. Not like I'm in workout clothes jogging, but if I need to get to another location quickly, I'll run with camera in hand.

The only disadvantage to using a short standby on the 40D comes when you're using one of the custom user modes on the dial. When the camera comes out of standby, everything will be set back to the settings you saved to that mode, including exposure (if you saved from manual mode) or exposure compensation (if you saved from aperture priority, shutter priority, or program modes).

This, in my opinion, is a bug. The camera should distinguish between being power cycled via the on-off switch and coming out of standby.

My solution to this is to set the standby time relatively high for the custom user modes. With it set up that way, if I'm going a long enough time between shots that the camera drops into standby, the chances are very good that the shooting conditions have changed significantly enough that I'd have to fool with the exposure settings anyway.

I'm not sure what I feel moving, but no I'm not focusing. It's only when I'm walking downhill because of the jolting steps and happens when it's either on or off. Anyway it was just a minor concern that I won't let bother me.

I know my Tamron lens will zoom out after long bouts of walking.
So often I zoom it in and lock it when I'm on the move.

Mine too, no issue AFAIK

I just dont understand what you mean by stuff "moving" or "jiggling", especially when you couple that with asking about it being on. The only time anything should move when the camera is on ( as opposed to being powered off ) is the AF and/or IS motor...neither of which should be "jiggling".

Does it not go in to like sleep mode after a while anyhow?
but I leave it on all the time, when I am using it anywhere.

I feel the same thing. It feels like a gyroscope inside either the body or the lens. I thought it may be the IS mechanism in the lens, but isn't it suppose to not be in IS mode until the shutter is half-way pressed?

.

I think what the OP is referring to is "Zoom Creep" - when a zoom lens creeps from one zoom extreme to the other due to slight jarring downwards movements when walking. I know this used to happen with my 55-200 (I soon figured out why, it was a c**p lens) and can easily happen with Push-Pull lenses like the 100-400

sometimes you'll hear a small clink or thud when jotting the camera around. this is normal. that is the vertical/horizontal sensor moving around (best way to describe it is as a ball in a diagonal tube. when the camera is horizontal, the ball is on the bottom, when it is vertical, the ball moves to the right side of the camera, which happens to be on the bottom, though it is actually more complex than just a ball in a tube). just keep doing your thing and everything's fine

I think what you feel/sense moving around is that anti-dust shake system. It's NOT harmful to carry your camera around while it's on.
