For a Canon 200/1.8 or Nikon 200/2.0 with the hood in the storage position. This is a lightweight alternative to our Long Lens Cases, which are designed to hold a lens with a body attached. This pouch is small enough to be worn as a belt pouch. This case is lined with 10mm (other lens pouches use 6mm) 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.
This pouch is also useful for carrying a 300/2.8 worn on a waist belt.

Here is quote from a customer that has the Canon 300/2.8 IS lens and stows this lens with the leatherette lens cap over the reversed hood:

"I am using the E870, which works much better [than the E584], although maybe it is a hair too large! However, with the E584 it was simply impossible to get the lens out quickly, and with the E870 I am quick draw McGraw."
