Some reference shots to gauge the size with a mirrorless kit. This is just the bag sitting on my desk, how I came home yesterday.
In it is the X-T2 with 35mm attached, 50-140mm on the right, 16mm on the left, below the "shelf", I had a battery pack in it too, and room left for another lens/X100T and/or a small bottle of water. In the inner pocket there are 3 X-T2 batteries, 1 X100T battery, lens pen, some batteries for film cameras, and some spare memory cards. The outer pocket was empty and folded flat. It is expandable if needed.
On the bottom, I attached my Gitzo 1541T as this is where you would store it if needed.
I normally travel with far less gear, but I had a portrait shoot yesterday and needed everything in the bag. The bag folds flatter, the less gear you put in it, which is nice.
Better shots and impressions will follow in the full review.
