WHITE CANON LENSES

http://photonotes.org/articles/beginner-faq/lenses.html

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

 

 

You guys just user cheaper glass than Nikon and Zuiko

A little Artsy shot

Firebird Intl Raceway on Sunday. There was also motorcycle races and an infiniti car club race going on the other tracks.

The26th and 27th is another big event with Boat Drags, Monster Trucks, off road trucks, and truck show. Unfortunately I can't go to that one- already have plans.

Nice shots DD & Aaron.

Aaron flying out at Gateway is kinda hit & miss, you never know what will be going on. I do have a friend that is retired and out there almost all the time and if he knows of anything cool coming in he drops me a email. He knows most of the ground crew out there so that helps but only with the fighters. The C17's park at a different part of the field and we never know what their schedule is, just have to have luck getting shots of those landing or taking off.

He told me the night before that those F16's would be in on Sat. I usually show up on or around 2-3pm when the light is getting better and see whats going on. Sometimes there is nothing out there other times you can blow threw mem cards in no time.

Usually there is a good mix of F18's, Harriers, T45's, & F5's. Week days not much happens, its all weekend stuff.

More fun at Firebird

And of course some of my patented silhouette work
