Coated Lens for a Solarforce L2P?

Heheheh. Sure, an actual AR coated lens has a very visible color cast when you look at the reflections in it. You’ll never mistake an uncoated one for a coated one or vice versa. Take a look at the OP in this thread for reference: P60 Kaidoman AR coated glass - Recommended! Pics inside

IIRC the trick is certainly to tilt the lens and look at reflections at a steep angle. Some AR coated lenses will be purple, some green.
