The black Lens Changer 75 Pop Down V2.0 from Think Tank with its pop down feature provides a safe and secure home for your 70-200mm f/2.8 or 100-400mm f.4 lens (or similarly sized lens). The lens pouch is designed to expand downward to accommodate your lens with its lens hood attached in shooting position as well as fitting inside with its tripod collar. This will save you effort when it comes time to remove the lens, mount it to your camera and shoot.
It's a mid-weight padded pouch with a top grab handle for easy transport. It also contains slip pockets for lens caps that always seem to get lost. Access to the lens is easy via its wide mouth opening and easy throw one-handed drawstring.
