Pretty cool new BR element, so quite an innovative lens...

 or two Sigmas 35/1.4. Looking forward to see it performing in a test. However, great to see Canon responding the challenge.

I assume this BR material wont be cheap, so like fluorite it might only be used on high end lenses. Still, it would be nice if more lenses get better correction over more of the spectrum. Personally I don't think I've ran into major problems with blue, but more at the other end with deep reds.

It is not the without the BR part you would have a "problem with blue", it is about being able to control part of the spectrum in such a way, that for the whole lens system all colours will focus the same.

It isn't a coating, but a new material with different refractive qualities making it useful to give a lens designer more possibility to correct for colour. @BC I wasn't saying that not having this part automatically means you will have a problem with blue. I was saying, in practice, I observe the deep reds as being particularly off on some of the lenses I use. It may well be that using BR, the blue end may be corrected more easily in one way, opening up the possibility of other degrees of freedom to better correct other parts of the spectrum than otherwise would be possible.
Still, all these are far enough in the future it isn't worth worrying about right now.

Awesome lens! Very very pleasing results (sample pictures: just click on one of those Photo1, 2 links) Great detail, awesome bokeh. Tip my hat, this lens is worth the money. More on BR on Canon page or Photorumors
What I like very much in the samples, the photog took some usually critical shots. These pictures are small although probably made with their 50 MP body. Not a slight hint of CA, also pleasing shadows but the highlights are in an extra class. Wow.

Indeed, the impression I get from these early sample images is that OOF parts are rendered quite agreeable, contrary to the pet peeve I have about the Sigma 35mm f1.4. The two 35mm f1.4's I did like, uptil now, where bokeh is concerned were manual focus lenses (the current Zeiss and the old Nikkor). This Canon has a way too steep price though, for me to think about getting one. But I am not the customer they target with it.
