Switching lenses mid-shoot has never been easier. The Case Logic DSL-101 Luminosity Lens Exchange Case not only protects an additional standard zoom lens (e.g. 18-135mm), but the open configuration creates a secure exchange pouch to store the removed lens while attaching the spare. Avoid juggling, balancing & exposing your precious gear to the elements with wire mouth construction that offers a third hand when replacing one lens with another. Comes with a tailored weather hood for additional protection.
