I currently own also the think tank security version 2.0 and although I love the case it's sometimes gets a little bulky to take with me if I'm doing a local shoot I use it for when I'm traveling on the road and need all my gear with me so I saw the think tank 20L backpack and for my sore on the pictures on the website and after speaking to a representative on the phone from B&h I was assured my needs would be met which would been two bodies the Canon EOS r1 and a Canon EOS R3, a Canon ef70 to 200 mm lens and a Canon ef24 to 70 lens as well as a flash. This equipment does not fit in the bag so I'm limited now to one body and maybe two lenses and that's to say the least disappointing.

The Sony FE 400mm f/2.8 GM OSS Lens has dimensions of 6.22 x 14.13", and the interior dimensions of the Think Tank Photo DarkLight Backpack are 18.5 x 11 x 5". Therefore, the bag doesn't have enough depth to fit the lens.
