The right lower pouch on the front of the vest can easily carry my Canon EF 300/4L with Wimberley lens plate and my EF 100/2.8 USM Macro with lens hood attached, separated by a padded divider held in place with Velcro. Like the side lens pouches, they are nicely padded and feature a full, padded flap held securely by both Velcro and two snaps.
