New Bags In Stock
I've harped on the lightness and convenience thing before - Billingham meets these requirements easily, as well as being good enough looking to pass for a fashion bag - if you are fashionable. They can be small enough for mirror-less cameras or big enough for full DSLR systems and are designed to be reconfigurable whenever you need to shift to a different load of gear.
Best of all, they are a long-term investment. They have leather trim and brass attachments and heavy twill straps so that they age well. You might change your camera or lenses...and you do...but you need never change your Billingham.
