What is up with this? This sounds too good to be true.

I am using a petri 7s veiwfinder now for my wide angles, mostly because it has such a nice gold tint.

Can I add a nice gold tint to my FSU lenses? Or possibly fix scratches on toss-off lenses with "cleaning marks?"

Of those, only magnesium fluoride coating is suitable, unless you want an opaque lens 🙂 Magnesium fluoride is the earliest and softest kind of coatings, originally introduced by Zeiss around WWII time.

But I admit, the price is tempting!

They do multicoating for reasonable prices, as long as you're willing to ship the elements.
