The Canon fits perfectly in the pocket clean - and even with the sun visor. Without Logo Canon relatively unobtrusive and also more compact than the original Canon leather case. Advantage here that the Canon neck strap can be used.
The hook is probably only for optical reasons. Can not imagine that now holds the camera to a backpack.
A star deduction aufgrudn the price. It's a small neoprene sleeve - no longer. Somewhere around the 10 to 15 EUR would be a fair price. 20 EUR are already steep - but due to lack of appropriate !! Alternatives, it is currently one of the few bags that fit (if you are not powers bear a huge camera bag).
