It's a great little lens. Mounted on my 1D X, it fits in the same Lowepro S&F Utility Bag 100 AW in which I carry the body only. My favorite use is that it goes in a pants/shorts pocket when I'm carrying the 1D X with 70-200 II on a Blackrapid strap. When I need a wider AoV, I swap lenses and just leave the 70-200 II hanging from the BR strap.
