I think Philosophy of Photography is the right place for this. Consider two possible kits: an ILC mirrorless body with 3 lenses or 3 fixed lens compacts with large sensors (mu43 or APS-C) at similar focal lengths. I don't think this would work for longer telephoto types like bird watchers, but as a walk around kit it would be fast, the "NY Reload" alternative to zoom lenses. What do y'all think?
