Quite intrested in the 70-300L.
Its a bit of a curious one that, no doubt the USM addition is welcome, I'll be interested to know how well it'll stack up against the current 70-300 on IQ.http://www.dpreview.com/news/1008/10082617canon70m...

Hah! The old 'Black cat in a coal cellar' shot .....Have to say it does look pretty good based on that one.

Can you provide some insight into what these graphs are showing?
I've not looked at any of these for a while and I never was sure what the various lines really meant - without a legend it's all a bite vague.
A link to the source might do it ..... depending on how much the source assumes one understands!

the higher up the chart the 10 LP/mm line is (the thick lines), the higher the contrast reproduction capability of the lens will be.
— the higher up the chart the 30 LP/mm line is (the thin lines), the higher the resolving power and thus subjective sharpness of the lens will be.
— keep in mind that the black lines show the lens wide open while the blue lines show the lens stopped down to f/8, so the closer these sets of lines are to each other the better the performance of the lens when used wide open. The very best lenses will have the black and the blue lines close together.
— generally speaking a lens whose thick lines (10 LP/mm) are above .8 on the chart should be regarded as having excellent image quality. Above .6 is regarded as "satisfactory". Below .6 is, well, below.

Thats crazy money. Surely they will drop sharpley in a few months when they stop being "new". Still, that puts the 400mm 2.8 at £1500 more then the 800mm 5.6
