Bike mounted camera bag Are there any bike mounted bags for a camera, that could safely hold my Sony NEX-5? I'd be happy enough if the camera fitted in with the 16mm pancake lens (as most of the shots are landscapes anyway). However, I was only able to find bags for cell phones or very slim compact cameras.

The camera dimensions without lens are per spec 111x59x38 mm (WxHxD); my own measurements give cca 114x63x39 mm. With the lens mounted the depth is about 62mm and the height just slightly bigger.

Here's a top photo to get the idea of the thickness: link.

I'd like a bag that I could mount on the handlebar, allowing a quick access without having to step off the bike for a quick shot.

Or are there some solutions I could modify to my needs (more or less easily)?

I'm open to your suggestions! Thanks.
Ortlieb used to make two camera-specific bags that you could probably keep inside their handlebar bag, the Aqua Zoom and the Aqua Zoom Plus. These are now discontinued but you can still find them for sale.

However, the Ortlieb Ultimate is a great handlebar bag that snaps on and off the handlebars, and also has a camera insert. I highly recommend the Ultimate, although the mounting is a little tricky to install.
