The Tiffen 3 x 4" 5 Green Hard-Edge Graduated Filter helps to specifically add a bright green coloration to skies and other bright areas of an image while allowing a portion of the image to remain neutrally colored. The filter's coloring is densest at the edge and tapers to clear by the middle, with a hard-edged transition between the density and clear areas. The 5 color density provides more green coloration than the 4 density filter.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. It measures 3 x 4" / 76.2 x 101.6mm.

Note: A horizontal orientation filter's line of transition runs parallel to the long side of the filter.

Provides a bright green coloring to select areas of the image.

Graduated filter design keeps a portion of the image neutral, resulting in a more realistic look while allowing for the sky or other bright areas to take on the color of the density.

Q: 1. In real life on the trail with a coat on does it remove off the shoulders and swing around easily? Will it set on it's bottom on the ground w.o tipping forward?

A: Thats a tough one to answer. Its a really nice backpack, but your question really can only be answered with, it depends; on your jacket, how you have the pack filled, etc. it doesnt really like to stand on its bottom, but the idea behind the bag is to lay it on its back so you can acccess the camera. So I dont think they really intend it to stand on its bottom. You can easily loosen the waist strap if you have a bulky jacket. Ive been happy with the bag.

Q: 2. I need to buy this pack and not the 450aw due to certain airline strict carry-on policy. My question is will the camera section hold: Canon 7dMark ii with 70-200f4 attached with hood, plus 24-105 with hood, plus tokina 11-16 2.8 with hood?

A: No way a 70-200 will fit in the actual padded area. Maybe if you put it in a separate padded pouch in the front pocket but even then you'd struggle fitting the other stuff. It's a very small bag.

Q: 3. Although it does not have hte flap, can it hold a 14 inch laptop?

A: No I would not use it to carry a 14 laptop with my kit. There is a dedicated pocket designed to carry a 10 tablet with good protection. I tried a 13 laptop in my bag and it only just fits in the rear pocket but protection would not be great, it is a good bag but not really designed with 14 laptops in mind.

Q: 4. Are all the internal paddings removable? Can the top compartment open up and turn it into one large storage compartment like a normal backpack?

A: Yes, and yes. It's a bit of a hassle though if you convert between a camera bag and a normal backpack often. Reason is, you have to remove all of the lower compartment padding, which is attached via Velcro, then remove the divider in between the top and lower compartments and fold it in. Then once you're done and want to use it as a camera bag, you have to reinstall everything in the same configuration you had it in before to fit your body and lenses. If the bottom compartment was a pullout separated padded bag, it would have been way faster and more convenient.

Q: 7. Does a 150-600 lens fit in the back?

A: Yes the Sigma 150-600 will fit into this bag no problem.

Q: 8. 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!

Q: 9. Are the material durable? Are they water resistance fabric that can stand light shower or wet ground?

A: Yes, theis bag is strongly water resistent due to a built in rain cover, and also the material is durable.

Q: 10. What are the dimensions of the camera/gear compartment? (I want to fit a Feiyutech g6 with GoPro attached, about 12 inches tall.

A: The floor on the upper compartment on my 350 lifts up making a over compartment about 18x 11
