Think Tank Photo Lens Changer 75 Pop Down V3.0 Lens Case (Black)

My favorite wildlife lens is the Tokina 300mm 2.8 prime. All metal build and a bit of a beast. Let's put it this way, the filter size is 112mm. It weighs 8 pounds. Lens hood is solid metal. They simply don't make lenses this tough anymore. It also happens to be razor sharp optically. But how to carry it without a backpack? I have a nice backpack that swivels around and opens from the back. But I find a lot of the time, I am not going on a trek, just walking around locally. I don't mind carrying it around on my speed strap, but I would like the option of switching out to another lens at times. So what to do.... I purchased an Altura extra large lens holder (the largest they make). Nicely made, but would not hold the lens hood. The other flaw was it only opens from the top. Needless to say, it worked, but I had to loop my lens hood to the strap, which was a pain. Mostly it relegated me to just going out with the beast, and leaving the Altura at home. Along comes Think Tank. I had already picked up the TT belt 2.0 (which is awesome), and the speed harness. I also purchased the smaller lens drop for the belt (for either my Siggy 18-35mm 1.8, or Tam 90mm 2.8 macro). Almost there I thought. I could attach the Altura lens holder to the TT belt easily, but the lens hood was always my achilles heel. That is until I picked up the TT 3.0 150 lens holder. The dimensions were similar in height, but WIDER. That caught my eye. The other plus was the side zipper entry, instead of top entry like the Altura. It comes with two elastic outside pockets. It has a built in space under the holder for an included 'raincoat'. It was too much to ignore. I pulled the trigger. Success! Lens hood reversed and I had a few inches to spare vertically. It also has a built in safety web on the inside, so if you forget to zip it up, the chances of the lens falling out are minimized. This baby is a keeper. If I can find a lens hood 2 inches shorter, I could store it ready to go. My lens hood is 6 inches long! Still, I doubt there is another lens holder out there that will carry my Tokina beastie. Certainly not one that is as well thought out. Their brand name is for real.... Think Tank.

Fits my Nikon Z 70-200 with lens hood perfectly. Easy access with front zipper.

Like all Think Tank products, this one is well thought out, well-made, versatile, and does the job it’s intended to do well. I got this particular bag to carry a 2X Tele converter on Think Tank’s Skin Belt and Speed Belt Pro. And I use it for that, although I find it is also useful to carry my 50mm prime or other physically smaller lens to swap out for a zoom. One caveat, which is not a flaw because it helps it do its quick-swap job, but it’s something to know about: This style bag does not close up 100%. It is a drawstring, which means there’s a small hole in the top. There is a flap that folds over the end of the lens to avoid direct hits, but if you are in a very dusty or debris blowing space, or otherwise are showered with debris, some may make it into the lens pouch. As a quick swap and store, install/uninstall space for a second lens, it’s perfect. If you need a sealed space, there are other think tank versions for that. But the belt attachment, including the ability to let it slide on the belt, or fix it in one place, is very useful. And once you get used to it, super easy to open and close one-handed.

Since the Sony 200-600 FE lens just came out, I have been looking for a lens case and other then the Lowepro Lens Case 13 x 32 cm that will fit this awesome lens. What I liked over the Lowepro is the Think Tank has the 2 front left & right side pockets for filters or lens caps NICE! Also they will hold the Sony 1.4x Tele-Converter in it a second NICE! Also this Think Tank has a built-in rain cover that the Lowepro don't, a third NICE!!! 8-31-2019 Update I just love this with the to Sony 200-600 and the belt holder from Amazon for $12.99!! So I can say for anybody that has the Tamron or Sigma 150-600 or the Nikon 200-500 THIS IS THE LENS CASE! The only gripe I have is the poor small carry handle come on Think Tank (you did not think here!) when your caring the case with a big lens as it was designed to that thin small handle is a joke! But everything else is great! THIS IS A MUST BUY and for $50 I was not sure I wanted to pay $50 but it's way better than the Sony thin case / pouch, and for $50 offers good protection all but dropping it on cement. Christopher

This is my 5th think tank pouch I use on their belt system. They fit lens very well and easy to swing pouches around on the belt if you need to squeeze through a crowd or to kneel down on the floor to get a shot. If I am not using the pouches for lenses I use them to hold water a bottle, cell phone, not pads, flashes, batteries and card. The draw string at the top keeps lenses in place and makes zero noise. Highly recommended because they work great with X style double camera straps and while working in a suit jacket.

Does not fit the Fujifilm 150-600. Just a bit too short. Otherwise a very nice lens case. I ended up with the Lowepro, but even then you have to torque on the zipper to close it in the Fujifilm lens.

Well designed, good materials, works as planned

Think Tank makes great stuff. This bag fits the designed purpose, but just barely. I mean, the Sigma 150-600, Sport or Contemproary, is a big lens and though is not as expensive as some of the other pieces of glass mentioned in these other reviews, it’s a lens worth protecting. That said, if you put a lens cap or UV/CPL filter on the Sigma, the bag has to be stretched out to fit. I’d store it with either/both on in this bag, but there isn’t enough give for both. With the rain pouch tucked in the bottom, the inside is pushed up into the front element. The lens hood cover does the same thing. The front element is recessed ~6 mm from the front of the lens body, but the protective hood makes contact with the front element. Over time, this will wear away the coating(s) on the front element. The design of the pouch exacerbates that. Granted, movement is required and the fabric is soft. I do automotive work and have seen plastic zip ties wear/cut through cast aluminum parts with little damage to themselves. To solve this, the bag needs to be a 5/8” or 16 mm taller and a solid piece of HDPE, LDPE, ABS, or some other rigid bottom in the base to protect the investment of whichever lens is placed in it. On the flip side, the girth of the bag is practically perfect. I added a THSM540 foot to my Sigma. It prevents the knuckle rub, but is also longer allowing for better balance on the tripod in a gimbal setup. All three attachment points, one finger strap and two for the back/shoulder strap are stitched through twice and are slightly over 10 mm, ~0.4”, wide. Dinky for some, but rather sufficient. If you have a belt/strap system, not just one to holdup your pants, to attach this too, you should be able to comfortably deal with up to about 2.5”, or up to about 65 mm, wide belts/straps. As for size, you can fit this bag, with lens inside, inside the Sigma bad provides with the 150-600. The center, zip-down-the-side, is perfect for a lens this size. You can easily rock the lens in or out of the case. Even with the lens hood on, though inverted. On the bottom, facing against the user, is a partially hook-and-loop sealed pouch that holds the rain/water cover. Clever, functional, but if you need it, remove the cover before placing a lens inside this bag.
