There was a camera shop at the air show called Pixel. They are located in Avon on Rt. 83 and Detroit Rd. They were offering all kinds of gear to use free of charge at the show. All you needed to do was leave your DL, and provide your CC info. They had many reps there answering questions and providing info.

I tried a Sigma 150-600mm lens. Not too bad. Was great for the warbirds, but definitely needs  to be on a tripod for the fast jets.

They are running some specials for about another week or so on various equipment. Here's their info for anyone interested:
