Q: 1. Will this pack hold a hydration pouch (3l)?

A: Yes, but it's not really designed for that. You can put the hydration bladder in the main pocket.

Q: 2. Takumar 50mm 1.4 on Panasonic GH4 using this adapter, will it work?

A: Yes it works

Q: 3. Is this a good fit for a 5'6 woman? I find that sometimes these bags are designed by men with men in mind...

A: I'm a 5'1 female and it works fine for me. The waist belt helps keep the weight of the backpack off the upper back, which is awesome because the shoulder straps aren't digging into my shoulders. I've hiked several trails through the Might 5 National Parks in Utah, Petrified Forest NP, Channel Islands NP with this backpack and did not feel that it is too big for my body.

Q: 4. Will this fit a Sony 7R2, 50mm lense and Mavic Pro and controller?

A: Yes, this backpack will fit all your equipment.

Q: 5. I see no evidence in the photos of “Body Side Access.” Is it actually there on the BP 450 or is this mislisted? Does someone have a pic of the opening in the side if it is there? Thanks!!

A: "Body Side Access" means that the opening for the camera would be against the body when wearing the backpack. The camera opening is securely against your back which helps from theft of your gear when wearing your backpack in busy urban areas, and it allows you to access your gear while wearing the backpack with the attached waist belt, and/or allows you to place your pack on the ground without getting dust or debris in the backpack or putting dirt on the back of the case. The images on our website show the opening on the side of the case closest to your back when wearing the backpack. There is no side access for this case, only body-side access. If you click the "Show More" link under the image, it will show more images of the case, including images of the open case, and the last image is an image of a model wearing the case and open while accessing the gear as described above.

Q: 6. is there a hip belt?

A: Yes, it has a one inch waste belt with plastic buckles.

Q: 7. What are the measurements for the camera compartment and the upper compartment?

A: Sorry, we are not able to measure the bag. From what information we have, the exterior dimensions are 10 x 6.7 x 17.3 / 25.5 x 17 x 44 cm with what appears to be the camera compartment interior dimensions being 7.9 x 4.7 x 9.1 / 20 x 12 x 23 cm and thus the top should be about 7.9 x 4.7 x 8 / 20 x 12 x 20 cm.

Q: 8. Will this adapter allow a vintage Rexatar 135mm 2.8 lens ( M42 pin mount ) to affix to a blackmagic pocket cinema camera?

A: It works great I havent had any problems. A great choice for the price.

Q: 9. Will this pack hold a travel tripod?

A: Yes, the external attachment points/straps on the back of the backpack would allow you to hold a travel tripod. If you have a smaller tripod, it may also fit in the easy-access side stretch pocket on either side of the backpack.

Q: 10. Will it fit Canon 5dsr with 70-200 2.8 IS version attached?

A: Yes, well... sorta. It should fit if you don't put much in the top compartment. I know for sure it will fit a 70-200 without a body, but with one I couldn't be sure. A definite fit would be in the size up from the 350. Which I have forgotten the name to. But other than that it is a phenomenal pack!
