Summary: I think a bag like this is a ncessity when storing multiple lenses in close proximity. I bought a few different versions of this bag for all my lenses and an upcoming trip to the Grand Canyon. While the bags do seem a bit overpriced they are made very well and look fantastic. Overall I would definitely buy this again.
Summary: Great lens case at an OK price. This case was recently hard to find, but BH supplied it in fairly quick time. It seems odd that Cannon doesn't routinely supply all their lenses with their respective cases at purchase, but they don't. Good to be able to find a supplier for them as lens cases are a 'must have' item.
