ACPROLC18 Ape Case Professional Large Lens Case is a strong and versatile way to store and carry your precious DSLR Lens and is made with the high quality materials and craftsmanship you have come to expect from Ape Case. This Pro Lens Case is designed to hold most modern 300-2.8 lenses. (please check interior case dimensions closely against your lens' measurements) The ACPROLC18 is fully padded and features an extra, removable interior base pad for even more protection on the case bottom where you need it the most. This Pro Lens Case can be carried with the supplied shoulder strap, or by hand with top loop handle. There is also a uniquely designed belt/loop attachment system that has a standard-type sewn-in 3.5-Inch loop for belt attachment, plus a stiff hinged openable and closeable Velcro clasp-type "attatcher" that can be used on a belt or used to attach to another case that has a loop (like our ACPRO1800, ACPRO1900, ACPRO2000 or ACPRO4000). The top opening is generously sized for easy lens retrieval. The dual zippers are joined together with a zipper pull that allows you to zip or unzip both zippers simultaneously gaining quick lid opening access. The lid is also secured with an adjustable quick release clasp. All together, the lid system allows for secure closure, yet quick and easy access. There is a slim pocket on the front of the case under the lid to hold memory cards. The case also features Ape Case's signature "black on the outside yellow on the inside" color scheme. The Hi-Vis Yellow interior makes seeing what is in your case a breeze.
