Q: 1. my RF100-500 lens hood is longer than my RF 70-200, I need a OEM replacement for my Canon RF 100-500? Not the RF 70-200

A: The Canon ET-83FW III Lens Hood is for both the 100-500mm and 70-200mm RF lenses according to Canon.

Q: 2. How tall is the Canon ET-160B Short Lens Hood?

Q: 3. How do you zoom with the neoprene on the barrel, or is it stuck at 400?

A: The sleeve that exactly fits over the barrel extended to 400mm attaches with a velcro strip. When you want to use as a zoom lens, you simply undo the velcro. I then refasten the velcro and hang the circular piece over my gimbal head where it can't get lost. When I hand hold, I just leave the extension cover off.

Q: 4. What's the little door on the side for? Filter adjustments?

A: Yes, when a circular polarizer or variable ND filter is mounted to the front of the lens, the door in the hood allows you to make adjustments without removing it or reaching in from the front of it.

A: No, it is not. The Canon ET-160W II Lens Hood for EF 600mm f/4 Lens, B&H# CAET160WII, would be the correct lens hood for use with the Canon EF 600mm f/4L IS II USM Lens. The Canon ET-160 (WIII) Lens Hood, B&H # CAET160WIII, and the Canon ET-160B Short Lens Hood, B&H # CAET160B, are designed for use with the new Canon EF 600mm f/4L IS III USM Lens.

Q: 10. Sorry I have another question. I am really considering buying this wrap. But it is costly! Do you really feel it gets you closer to birds if you are also wearing camo clothes and hat? What if you are not wearing camo clothes, then does it even matter? Thank you.

A: I would say that it can, provided you are stealthy in other ways as well (no sudden movements, camo clothes). Breaking up the head profile is important, because birds get most nervous when they perceive they are being looked at. But it won't fool birds all the time, and there are limits.The wrap also protects your lens from scratches, so you could look at it as an investment, if you ever want to sell your lens one day.
