Camera sideways in bag?

So I got a bag for my 30D, and with the lenses etc, the camera will only fit in it sideways (seperated by padding of course). Will this do harm to the camera by turning it on its side to fit in the bag?

Not from my experience as long as it is padded. I've seen many folks pack their backpacks this way.

Nope - I routinely have stashed whichever camera had the longest lens on it this way and in 30 or more years haven't seen any problems.

The only thing I can think of is the pop up flash. Might want to make sure that the pop up flash is pointed in the direction of least pressure. I have never had one break, but I do store them LCD screen down so the pop up can be pressed against the outside of the bag. I make sure that it always points into the bag presenting the camera base at a target incase something bumps the bag hard.

I store the bod grip up so I can retreive it ready to shoot.

Thanks for the comments

This is why you spend good money on a good bag.
The major brands do research and testing to formulate the textiles and padding materials.

As long as your gear is supported properly, you should not have any problems.

I carry a 30D with a 70-200 attached in one position and a 20D w/a 28-135 at 90° to the other, both with hoods. I have 4 or 5 othr lenses packed with them in addition to all the misc. stuff.
I pay no attention to the position of the rolling case as I know they are supported the right way.
