We have a show coming up and one of the locations we're shooting at has very tight space for equipment, camera, talent etc... We've been discussing using mirrors to shoot into in those tight places. My question is if there would be a huge difference investing in optically pure mirrors (0 abberations in the glass) vs. standard mirrors? The DP has asked me (key grip) to research this because these optically pure mirrors are new terms to both of us. Any suggestions would be greatly appreciated. We're shooting on Fuji Eterna 500T with the Arri SR2.

I would think you would need a front coated mirror. Most mirrors are coated on the back side creating a double image and a green tint.

Definitely front silvered (coated) mirror. I've only worked with small ones on a film about five years ago.
The surface coating is quite delicate so needed to be handled with kid gloves (literally!).
Costlier than expected to buy if I remember correctly. Probably because the demand comes from scientific sectors.
