Q: 6. 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.

Q: 10. How does this lens perform (effect on IQ) with the 1.4 and 2 TCs?

A: When using the Canon RF 400mm f/2.8 L IS USM Lens wide open with the Canon Extender RF 1.4x, image sharpness is decreased modestly in the center in the center of the frame, but corners are nearly unaffected. Stopping down one stop brings a nice improvement and impressive sharpness across the frame. The RF 1.4x adds a slight barrel distortion but notably does not affect lateral CA. The results are a bit soft when using the Canon Extender RF 2x on the RF 400mm f/2.8. The sharpness is good across the frame if you stop down one stop. The 2x Extender increases lateral CA noticeably and barrel distortion slightly. The 2x Extender does impact sharpness and contrast.
