Sigma Announces 85mm f1.4 Art, 12-24mm f/4 Art, 500mm f/4 OS Sport

I found that the Lowepro Flipside 500AW bag is fantastic for carrying around medium size telephoto lenses.
I used it with my Sigma 120 300 F2.8 Sports lens and the lens fits perfectly in the bag with lens attached. I found the photo on internet to support my statement

It appears that Sigma 120 300 F2.8 lens size is 52mm shorter than the Canon 400 prime. So the 400mm prime still fits but the body will have to be detached form the lens:

Sigma 120-300mm f/2.8 DG OS HSM 7.50 lbs (3390g) 4.9 x 11.5" (124.4 x 291mm)
Canon EF 400mm f/2.8 L IS II USM Lens 8.49 lbs (3850g) 6.4 x 13.5" (163 x 343mm)

2. Be more compact

Doubt that. That is one thing I like about the Canon 100-400 mk1 (no idea about the mk2); it collapses into 70-200mm body size so it fits in a lot of bags, with body attached. Good luck doing that with the 400mm prime.

I would buy a 500mm f/5.6 L IS if Canon comes out with it. In the mean time I prefer the 400mm f/5.6 for BIF and 100-400mm II for more general shooting when I need reach. When I am reach limited I use the 5DsR if at all possible. I have two problems when using the 1.4X TC III and the zoom: atmospheric distortions rendering any additional reach meaningless, and focus accuracy when the subject has minimal contrast vs. the background.
