A good point, but then why white lenses are exceptionally rare? Why aren't these matched by white bodies designed for hot climes? I have much doubt about the choice of color for the new 70-200 GII was decided on the basis of some physics.
Is plastic originally black and white color paint is extra production process/cost?
They still had to paint metal bodies of 70-200 and super teles. White is a more reasonable choice.
When you come to places such as Southern Turkey - you will see that 80% cars are white.
You can feel how much heat a 1kg 135mm lens can accumulate under direct hot sun. I never used super teles but can imagine that heavy lens body and large heavy glass will get hot and stay hot.

White lenses reflect sunlight and in sunny, hot climates will be cooler than black ones. The physics of a lens barrel can change the relationships of the lens elements in the presence of heat.Is plastic originally black and white color paint is extra production process/cost?
