Think Tank Photo DarkLight Reviews

Excellent all around

By Bradley
Rated 5 out of 5
Date: 2026-08-18

This is a great bag for me. It has a top load for quick access to my camera without having to undo everything to get to it. The lens and extra camera space accessed through the back are excellent. I like that the laptop pocket is accessed from the outside/back. It is comfortable and light.

20L Carry Capacity

In my Darklight 20L, I have managed to fit all of this: Canon 6D Mark II Canon 28-300mm f/3.5-5.6L Canon 100mm f/2.8L Macro Sigma 24-70mm f/2.8 Canon 17-40mm f/4L Canon 50mm f/1.4 The best part is that each lens fits properly in its own spot, and nothing has to be shuffled around when I attach a lens to the camera. I could technically bring one more lens, too! I think a 70-200mm might also fit if it stays on the camera for travel, but I don't have one to try. * Sigma 160-600mm fits very comfortably in terms of length. It's wide enough with the lens hood that the padding would have to be rearranged. Not really my preference at the moment. ** Yeti 26oz Rambler does NOT fit in side pocket when that side of the bag is full of lenses. Once I took my two lenses off that side, I could fit the bottle. With the lenses, I'd say the Yeti 18oz might fit... I'd say just use this side for tripod only. Manfrotto BeFree fits great! *** Lowepro ProTactic Bottle Pouch III fits great on the side with the straps. This will comfortably hold my 26oz Rambler, and I could even squeeze in the 36oz! Highly recommend if you need to pack hydration. I also have the 14L but haven't fully customized it yet. I wanted to focus on the 20L as it is the middle size.

Can I fit the Sony 400GM with room to spare. A second body and few other lenses?
Asked by: Matthew
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.
