Being a recent Canon convert I realize I have a lot to learn and I am learning fast but I have a question about the Canon "L" lenses.

Other than the color of the body, is there any difference between the White "L" lenses and the Black "L" lenses? I am looking to pick up a couple of the "L" lenses and I want to make sure I get the absolute most for the dollars I spend.

Thanks

I have both (Black & White), and as far as I know there is no difference between them as far as glass goes. I have always thought the white ones were more for outdoor/locaton work. But that's just my opinion. BTW, I love them all!

DAve ..I have used Canon for 30+years. AS far as I know, the white was for heat reflection due to large surface area...but could be wrong..I have both and see no difference

The following is from Photonotes.org

"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."

Full dissortation on Canon lens can be found at photonotes.org here

Just one of many sources of information on Canon lens on the Net.

Yup, heat reflection it is. Black sucks up the heat, while white, off white or grey, call it what you will, reflects heat, protecting the glass elements inside from expanding. Smaller 'L' lenses, like the 24-70 (I have the older 28-70 2.8L) and 16-35/17-40 do not have as much surface area for heat absorption and so expansion of internal elements is not a factor.

I've used both types and I see no real difference. I don't think the white color is going to give you much heat difference between black. If that were really a major concern, then why have the other lens makers not long ago latched on to the idea?

Some of the Lens are better than others. There are also some great alternatives to L lens from other manufactures. For example, if you were considering a 70-200 2.8 (non IS) L lens, then the Sigma 70-200 2.8 is rated almost identically to it and I can testify gives fantastic results. It sells for 50% less than the corresponding Canon L lens.

Cheers,
rfs

The L series lenses are generally excellent and Canon clearly puts some clever engineering in there, but you should not automatically assume that any Canon lens without the L badge is sub standard. A good example is the 85mm F1.8 that is wonderfully sharp and handles beautifully.

From recent testing it seems to me that the L series lenses have higher contrast and warmer tones than the standard lenses. You may or may not prefer that, but for the sake of colour consistency when swapping lenses on a shoot it should at least be noted.

I always thought that it was anything over 200mm (with exception to the 70-200L) that was white. These are the lens that would most likely be used outdoor for sports or wildlife.

Nikon uses black for their high end telephotos, and I dont hear people complaining about the image quality or wishing it was white.

I use a Sony and the legacy Minolta glass is white for the "G" line of telephotos.
I personally like the off white color of minolta better than the white of the Canon L.

I have some G level minolta glass, and I have friends with "L" canon and others with hgh end Nikon glass. I dont find many complaints with any of them.

Wow, a blast from the past. I bet the OP has a bag full of L lenses by now.
