Shimoda Core Unit DSLR RST XL50, 520-455
RST stands for the rear, side, and top access points of the Core Unit. With the RST50 (DSLR - XL50) Core Unit, you can access all your gear from the rear, quickly reach your camera from the side without putting your backpack down, or operate longer superzoom lenses from the top without having to open the back panel.
The RST50 is specifically designed to fill the entire main compartment of the Action X50 backpack. This means it can accommodate lenses up to 53 cm in length, such as the Sony/Canon/Nikon 600mm f/4.0 (mounted to the camera body), as well as the Sony 200-600mm and 400-800mm, Nikon 180-600mm, Canon 200-800mm, Fuji 150-600mm, and OM 150-600mm. These superzoom lenses fit even when mounted to a camera body. PLEASE NOTE: RST Core Units are not compatible with the Shimoda Explore series backpacks.
Shimoda calls them Core Units because they form the heart of the Shimoda system. Thanks to their modular versatility, users can customise their setup with different camera inserts for different days, getting more out of their backpack. While the RST50 can carry the maximum amount of gear an X50 can handle, the ability to swap the Core Unit for smaller versions gives you the flexibility to choose the most suitable Core Unit size for the adventure ahead.
