I plan to start taking some rides with my DSLR, a Sony Alpha 300, and I discovered that Ortlieb has a camera insert for their Ultimate handlebar bags...

It is a bit expensive to get an Ortlieb and the insert, so I am thinking of going to the local place that does foam padding and seeing what I can do to fit some foam into a less expensive bag... Or maybe the Ortlieb insert in a less expensive bag of similar size might be an option.

I will probably end up with a trunk bag on my front rack with some sort of foam insert. Probably enclosing he foam in a lint free cloth of some type to keep specks of foam from getting into the camera and/or lenses.
