hi!!
Is this makes any diference?

Yes, it does in certain situations (when the sun hits the lens from a specific angle)
That will reduce the glare.

Hi, I would not recommend you use the accessory which is not tested. Thanks for your understanding.  

I saw no real positive impact. This one blocks the top portion of any pano. Gimbal protection is the only real benefit I could see in minor crashes.

I don't use these hoods - found them quite pointless

Thank you all!!!
