Casio introduced a transparent ceramic lens in their Exilim line
camera, model EX-S100 a few years ago. Has the ceramic lens been used
in other Casio's digital cameras? What about other digital camera
manufacturers? Will ceramic lenses eventually compete with glass
lenses? Will we see Nikkor and Canon lenses made of ceramic in the
near future? Or, do ceramic lenses only compete in small size lenses
(small digital cameras like the exilim line) ?
For those who own the Exilim Ex-S100, what kind of picture quality
that is obtained from this camera?
Thanks for info.

I may be misunderstanding something but isn't glass a non-crystalline
ceramic?

I suspect that Casio simply thought it worth mentioning that their
lenses were galss rather than plastic as is commonly found on cheap cameras.

Ah I've looked it up: the lenses were made from Lumicera:-

Apparently it has a very high refractive index compared to glass.

The only place were transparent ceramics is acceptably used in is electric
cooktops. There's no place for this material in optics.

Thanks for the highly qualified comment. Could you elaborate if I am right
that calcium fluoride is good for teeth only?

I understand your sarcasm. She should forward this question to the guys
created Canon GL2 using these lenses

Don't mind Rita. She's known for her many crockpot statements.

Maybe Rita knows more about cooktops than optics.

A much more universally accept chemical would be glycolic acid. It works
for everything from a facial peel, teeth whitener, tub and tile cleaner, to
cement cleaner.

THANKS! You just solved one of the greatest mysteries in the photography
world if you are correct. Do they use ceramic lens elements in the Canon
16-35/2.8? This would be a logical conclusion since glass wouldn't yield so
much light falloff in the corners.
