Brighter days = photography
Binary Shadow:
Arrived yesterday so hopefully get out at the weekend to try it out.

I like the lens but personally couldn't justify the price. Then it's white... :/
Considered the Tamron 70-200MM f2.8 lenses but they have focus breathing issues. Thing is so do Sigma and Nikon versions.
zpyder:
I'd never actually heard of the term focus breathing before, and had to look it up, interesting stuff!
As to the whiteness...I too kind of thought it looked odd to start with. Much like why people buy Silver bodies and then put black lenses on.
But you get used to it, and technically it's not about standing out from a crowd with the white expensive lens. The official answer from Canon is the white reflects more heat, so if you're for instance a nature photographer on safari, in the glaring African sun, then a big black lens will likely absorb more heat and expand and affect the IQ of the lens much more than a lighter coloured lens.
I guess the way to test this would be to have two identical camera set ups, but put a tight fitting black cover on one of the white lenses, and on a really sunny day go out and take some photos. I wonder if there'd ever be a noticeable difference in quality.

Some example shots of the 100-400 II, from the Mauritius trip.

This ones a bit of a cheat as I used a 1.4x extender on it. But given it's a tiny fast moving subject, it's pretyt good that even losing a stop you can get results like this.

And on the day this photo was taken, I put the weather sealing of the lens and 5D body to the test

Suffice to say, it failed:

An overnight stint in a bag of rice brought it back to life. It's working fine now, though I should really send it off for a service before any corrosion sets in.

And two rarities, a pink pigeon and a mauritian kestrel. Both these species are mega rare, rarer than pandas and tigers. At the end of the last century there were fewer than 10 individuals or both species left in the world. Through conservation efforts though, they're now at a stable population on their native island.

I first noticed Focus breathing on a pair of cheap 70-200mm lenses, this link confirmed it. Also covers the white issue, and a few other bits.

You can just put a white or camouflage cover on the black lens, although no other manufacturer seems bothered about the issue. I would have thought keeping the camera temperature down would be more important yet their cameras are all black. And why have a white lens with black rubber? It would be fairly easy to make white rubber instead and the price isn't the concern here.
