I recently purchased an ID Bag (Black/Forest/Cayenne) and am giving it a test run as a photography bag.
Here are photos of the bag with a Tenba camera insert, a Canon 50 f/1.2 L lens (left), Canon 5D Mark II with a 24-70 f/2.8 L lens attached (middle), and a Canon 70-200 f/2.8 L IS II lens (right).
The fit is nice and I am looking forward to trying it out in the field.
