The Sightseer lens pouch comes with:
-1 false bottom divider, you can stash memory cards or batteries under this or even stack lenses by using it as a divider in the single pouch.
The Medium Lens Pouch is designed for your midrange zooms.
The Medium-Wide Lens Pouch is designed for your fatter primes such as the 105 f/1.4 OR the Nikon 14-24 2.8.
These pouches and accessories (sold separately) can be attached to the Sightseer Lens Bag via the metal clip in the back. This idea is derived from the standard for military use modular systems.
