• The E584 is for a Nikon 300/2.8 lens with the with the hood in the stowed position and with the leatherette cap in place.
• Although not confirmed, this case should fit the Canon 400/4 DO lens.
• This is a lightweight alternative to our Long Lens Cases, which are designed to hold a lens and a body together. This case is lined with 10mm closed-cell foam. The bottom has a tough 13mm PolyCore™ insert, which is same material used in the side-walls of our PolyCore™ long lens cases.
• Note: Because of the sung fit on this pouch, if you want to carry a 300/2.8 attached to a waist belt, the we recommend the E870 pouch instead.
