My DP2M and DP3M are on their way, but I expect to use them with the ThinkTank Retrospective 20.
(Note that I added padding to the bottom after I had a lens damaged when the bag fell from 50 cm to the floor! Poor design in that respect. But the extra padding does the job.)
I now use it with several combos, notably the Agfa Super Isolette and Contax G1, anything really except for the Rollei 6008i.
What I’m curious about is tripod use. I have a tripod bag, and a small tripod will never fit the bag (and anyway, it would make it too heavy). Will I opt for monopod? Not sure yet.
