There was an article somewhere showing heat absorbtion test on white vs black. I don't remember the specifics, but some canon guys were quoted as saying that the white reflects heat from the lens at a measurable level which is supposed to aid lens function and protect the internals. I honestly can't remember if this also assisted capture quality or not.

Canon sell a number of lenses in a special series they refer to as L for “luxury.†These are their most expensive and highest-quality lenses, and are readily identifiable by the red stripe painted around the end of the barrel. L series lenses offer higher optical quality than their non-L equivalents, and have an important technical aspect in common. At least one element in every L lens is either made of fluorite crystal rather than glass, is a ground aspheric lens element (not a moulded/replicated aspheric lens as used in less expensive lenses) or is made from ultra-low dispersion glass. Most L series lenses are also sturdily built - many are encased in metal barrels and are weatherproofed - and most are very fast lenses for their focal lengths. Nearly all telephoto L series lenses are also off-white rather than black. These lenses are, therefore, marketed as professional camera lenses and are usually priced out of the range of most consumers. They can be used to take great photographs, but the cost, weight and size of these lenses are the tradeoffs. Of course, a lens doesn’t have to be an L series lens to take good pictures. Many EOS lenses offer excellent optical quality - they just don’t need and thus don’t have exotic fluorite lens elements and so on. Many of Canon’s prime lenses in the 35mm to 135mm range fit in this category - see below. Note also that the presence of a red ring around the end of a lens barrel only indicates an L series lens if it’s actually made by Canon. Some other makers happily paint red stripes around the end of their lenses too, but this in no way guarantees that the lens meets the quality standard of a Canon L lens. Why are some Canon lenses painted white or silver? Nearly all large telephoto L series lenses have barrels constructed from solid metal and painted off-white, rather than black plastic or black-painted metal. Canon say they do this since white surfaces absorb less heat than black when used out in the sun, and fluorite crystal lens elements are sensitive to heat - they can expand and contract, altering their optical properties. Of course, the fact that a white-painted Canon lens stands out in the crowd is probably part of the reason as well. Look at any major sports event and you’ll see rows of hefty white lenses. Though to confuse matters Nikon have also begun to sell some lenses in optional white paint. A few lenses intended to be sold as kit lenses with silver-painted camera bodies have also been available with silver-painted plastic barrels. These include the 35-135 4-5.6 USM (to match the silver-painted commemorative edition of the EOS 10/10s which was released to mark the sale of 60 million Canon cameras), the 24-85 3.5-4.5 USM (to match the APS IX camera) and the 28-90 4-5.6 USM II (to match the Rebel Ti/EOS 300V/Kiss 5). The silver paint on these midrange and low end lenses is purely for cosmetic reasons. Click here to view and/or sign the petition

Cream coloured lenses are offered from Nikon, Canon, Minolta, and I believe Sigma. (Any body know if Lieca uses cream on their premium lenses? I think it's black on all, but I'm not sure.)

Personally,. I can't stand the white! (I know,. Heresy,. and I am going to be flamed) ...but having switched from a relativley low profile Black Sigma 70-200mm to a glaring White Canon.. well,. I do not at all like the additional attention  I have even considered selling the Canon and buying back another Sigma simply because of the issues the White lens has caused.  I have also considered destroying the resale value of an $1,800.00 lens by painting it a matte black. If Canon offered an option,. my lens would DEFINATELY be black...

Of course I will have to get a 300F4 first, but I want one of those covers! Someone has to make one for the 100-400 and 70-200. Any clue? Ian (®Feathers & Fur)
