This Kenko Aosta lens case protects your equipment for every possible danger. The bag offers protection to your Tamron or Sigma 150-600 mm lens. When capturing footballers at competitions, wild animals or other subjects that you do not want or can not get close to, you can easily hang the bag over your shoulder. Your UV or polarization filter is stored in the storage compartment on the inside of the bag. If you want to attach this telephoto lens to your body and store a smaller lens, there's plenty of room for it in this Kenko Aosta lens case.
