I was looking for a small and handy pocket for my Sony Alpha with Tamron 18-200. I opted for the Tamron c-1503 because it seemed ideal by their dimensions. The Sony Alpha fits with the Tamron 18-200 into exactly with attached Sonnenblende.Sonst fits into the main compartment nothing more rein.In the side pockets can be even one or two filters, or cleaning cloth etc reintun, into the compartment in the upper flap also. It has such a compact bag there when you have time go out with small luggage will.Sie 2 zippers which are sometimes a bit cumbersome to zukriegen on or, so it's no fast attracts ash. I like them and they served their purpose in me.
