In fact I think Zpyder had a thread about camera bags not too long ago...
http://www.tekforum.co.uk/posts/list/17405.pageIm now wanting to find a backpack style bag that is big enough to fit the camera kit I want to take with me (most likely the macro and a generic zoom) as well as typical walking kit (first aid kit, softshell, waterproof, water and food). At the moment Im lugging my normal backpack around with the Lowepro bag I have slung over my neck too, and theres no way I could do that long distance.
