Think TankStreetWalker HardDrive V2.0 Camera Backpack

This bag is definitely worth its price. Its slightly expensive compared to some of the other camera bags out there but it fulfills all my camera storage requirements.This bag has ample space for:- 2 cameras- 16-35 mm FX lens- 85mm FX lens- 18-35 mm DX lens- 70-300 mm DX lensI am planning to buy a 200-500 mm lens and there is enough space to fit that lens as well.This bag has additional 2 compartments inside the bag for storing stuff like memory card, batteries, charger. Other than that there are two compartments outside the bag to keep stuff like wallet, phone, flashlight etc.There is one big flat compartment on the inner side to keep documents etc but the only con is that the chain can be easily opened with one noticing, but there is a provision to lock that compartment as well as the main compartment where camera gear is stored.It also comes with rain pouch and additional straps to support longer tripods.The quality of the bag is excellent - material, chains straps etc. It also has back support for wearing it for extended periods.The internal paddings are thick and amazing for camera protection. But these thick paddings make it big enough that it probably wont fit in airlines below the seat. One trick that might work is to remove some of the paddings at the top of the bag so that the bag can be squeezed if needed.

This bag was recommended to me when I bought my big 400mm telephoto lens. There's lots of room in the bag, enough to fit my biggest lens with a pro body attached as well as another body, a 70-200mm lens with my 24-70mm lens up to. The big side pockets handle my monopod perfectly with the opposite side free for a good size water bottle. There's a pocket for a laptop that easily holds my 15" laolptop and iPad at the same time even when the bag is packed full. The pocket that pulls out from the bottom holds the feet of my tripod while the straps lock it into place tightly. If you're looking for a bag with lots of room that you can configure to best suit your needs the think tank bags are some of the best I've ever used. The shoulder straps are quite comfortable even when the bag is fully loaded.

The StreetWalker HardDrive v2.0 turned out to be worth the purchase. The padding for the back is nice and thick. There are grooves in the padding so when I took this on a long hike in hot weather it allowed some air flow. It felt light even though I had plenty of gear in the backpack and that may be due to the top strap that goes across the chest and the bottom strap that goes across the belly. I snugly fit my 32oz Nalgene bottle for water in the side pocket. There is a small strap inside of the pocket that I used to attach to the bottle just in case I tumbled down a hill. It also came with a rain protection cover.

Pros: Bag is sturdy and stands upright when you need it to.I am able to carry:(2) GH5 (regular model and S model) cameras with Lenses and Battery Grips attached.Extra 2 or 3 lenses.2 XLR adaptersCleaning kit, wireless LAV micsLaptop and power cableBattery chargers and AC adapterExtra accessory bag with batteries, cables, etc.Even with all that, the bag is comfortable to wear. I'll be taking it on business trips soon.Cons:The front zipper pockets have small mesh pouches but need either zippers or velcro to close. Otherwise, all items are fair game to roam free. Just be aware.Overall very happy with the purchase.

Fits my two main camera bodies and lenses perfectly. Nikon Z9 with 400 2.8 and Z8 with 70-200 2.8.

I've purchased many camera bags over the years. Some of them I use for different purposes like travel or wildlife photography. Some of them have worked out while others have not. I purchased an expensive Think Tank Shapeshifter bag a few years ago that DID NOT work out as it just did not hold enough lenses securely. It now just takes up space in my closet. This one I purchased, specifically, to hold EVERYTHING that I take to a wedding shoot. Here are the items that fit perfectly into this bag:Canon 1D X BodyCanon 5D Mark IV Body (with Battery Grip)35mm 1.4L II Lens50mm 1.2L Lens (very big for a 50mm)85mm 1.8 Lens (will also hold the 1.2L or 1.4L - I don't shoot 85mm unless it's too tight inside for my 135mm)100mm 2.8 Macro Lens w/Hood135mm f/2L Lens w/Hood16-35mm f/4L Zoom Lens w/Hood24-105mm f/4L Zoom Lens w/Hood70-200 2.8L Zoom Lens w/HoodCanon Speedlight (the big one)Tripod (will even fit my largest Gizmo)13" MacBook Pro (will probably not fit the 15")iPadiPhoneWater BottleBatteries, batteries, batteries, wallet, keys, cords, chargers... (you get the idea)To summarize: TWO professional camera bodies, EIGHT camera lenses, flash, laptop, tablet, phone, everything! The bag is not that large, but it's rugged and all that equipment feels very very safe. While it probably weighs 50+ pounds fully loaded it is still comfortable enough to lug from the car to the venue and back. I would not want to go on a hike with that much equipment, for sure.Basically, this bag does what I intended it to do, which is allow me to take everything I need to a wedding shoot and only have to keep up with a single bag (two if I'm doing off-camera flash). You can even lock the main compartment with a small padlock if you don't trust that video guy to not sneak off with some of your L glass (just kidding - but seriously). I'm sure this bag can adequately meet other needs as well in different configurations. Good luck!
