Mini Test: Think Tank Digital Holster 150 V3
Posted on May 15, 2026 by Pro Moviemaker
If you regularly work with a big sports or wildlife set-up, you will be familiar with the problem the Think Tank Photo Digital Holster 150 V3 exists to solve. A backpack offers protection, but it slows access. A bare shoulder strap is speedy, but not exactly confidence-inspiring when you’re carrying a gripped body and a long zoom. This holster is aimed squarely at that middle ground. It’s quick to grab, lighter than a full bag and purpose-shaped for a camera-and-lens combo you want ready to shoot.
Think Tank says it is designed around a gripped or standard body with a lens up to 30.5cm/12in long attached, and gives examples such as a Nikon Z 9 with 200-500mm or a Sony Alpha body with a Sigma or Tamron 150-600mm fitted.
I used it to hold my Sony 300mm f/2.8 with the A1 camera and battery grip attached, and it’s a perfect fit. The bag Sony provides with the lens is too small for the body, so the Think Tank is £129/$130 well spent. And few brands offer anything similar.
It’s obvious that this is not a general walkaround shoulder bag, and it is not pretending to be one. At 0.8kg/1.75lb, it is not ultra light, but it clearly prioritises shape and structure over shaving off every last gram.
The strongest thing about the design is that it is genuinely thought through for field use. The top-loading access is fast, the lid opens away from the body for easier retrieval and there are several storage points around the main cavity. There’s a large front zip pocket, a zippered pocket on the outer lid and an accessory pocket under the
lid for cards, caps and small bits. There is a rear attachment point for Think Tank belts and some backpack waist belts, plus an attachment rail for compatible modular pouches.
The carry options are another plus. You can use the top handle, removable non-slip shoulder strap or the rear loop/belt attachment. Think Tank also includes a rain cover, which is exactly the sort of practical extra you want on a bag aimed at outdoor use.
Protection is well judged too. The removable soft divider that shields the rear LCD from the camera strap is a small but clever detail – the kind of rubbing pressure point that could’ve become annoying over time. Think Tank specifies YKK RC Fuse zippers and water-resistant materials. It’s a bag made for regular use rather than occasional weekend duty.
Where this holster will win fans over is speed. For shooters who work with one body and one long lens for extended periods, a dedicated holster can be much more practical than repeatedly taking a rig in and out of a backpack. It is undeniably fast to use.
Its main weakness, however, is how specialised it is. If your set-up often changes, or you need room for multiple bodies, a drone, a laptop or extra lenses, this is not the right tool. It won’t fit all super-size lenses. The 150 is the XXL version and is sensible for wildlife and sports combinations.
