A Question About Lenses Color

Hi All

Why Canon had choose the color white for the Super Telephoto lenses?
and some of the Telephoto Zoom and Telephoto lenses?

other brand like Nikon , Olympus and Sigma
the color of the lenses all black !!!!!

and thanks

Put a large black lens out in the sun for awhile, now do the same with a white one. The black one will be much hotter. Its also a status thing. Everyone knows you've got Canon glass.

Why? My username says it the best!

Reflects light/heat or some shpiel like that

Red on White. The colors of the Japanese flag?

thanks all
i think i got the right answer from ljason8eg and Jericobot

Thanks again

Some Nikon lensese are/have been available in white also, btw. And some Sony lenses are too. Despite the majority of white lenses being Canon, not all of them are.

As far as I can remember, the fluorite elements in the more expensive Canon lenses react more to heat more than standard glass (expansion I suppose). As a result the off-white paint helps to reduce the amount of heat transferred into the lens.
I think its also the bigger lenses that have white paint - I guess becuase there is more surface area?

Not sure whether they're still available, but the 70-200 and 300 F/2.8 both were available in white, I'm fairly sure of it.
