Best Bag For 2 Mirrorless and lenses
Have you looked at the Domke bags? B&H have them and have very good product photos. The models you might look at are the F-2, F1X or the F3X. These are great bags, canvas, don't scream "camera" bag, and are very durable and are very comfy to haul around. My favorite are the smaller FXB bags, perfect for day bags with one body and a couple lenses. And the Rugged Wear line are a really cool waxed canvas that are very weather proof.
Here's a link of a good site that shows all different types and brands of bags reviewed by consumers with how they've loaded their kit.
