I’m still thinking over my impressions of using the Urban Design in the field, but I will say this: it’s intended purpose is technically to make it easy to have quick access to your equipment while shooting. It does fill that need pretty well.
In theory, I might be out shooting with a telephoto lens, and suddenly want to shift to a wide angle. This happened when shooting the ice pic from the other day. The nice thing? Well, I was in a light rain, yet was able to angle myself quickly and efficiently to swap out lenses without getting the insides wet.
So that’s a nice feature.
Plus, I got to test their (included) all-weather cover. It works as advertized!
