Fits a 5D mark ii with a Sigma 85mm lens with extended petal hood with lots of extra room. For the money, you might be able to find something that works just as well, but I'm sure you won't find something with as good build quality.The only thing I dislike is that the Velcro around the lens is exposed so you won't be able to stow the camera away in your bag with the raincover installed... the Velcro tends to attach itself very affectionately to the inside of camera bags.
