Think Tank photo has launched a new line of protective lens cases it calls Lens Case Duo. The six cases in the lineup feature a soft, padded liner and two zippered access points: one from the top of the case and one from the side.

Each of these cases can be used on their own or together as a modular system. The two methods of accessing the lens inside make it easy to pair with either a belt system or stuffed inside a backpack — whatever your setup requires. The larger cases, designed for massive primes and telephoto lenses, include a shoulder strap in the event you prefer to carry it as a sling of sorts.

Currently, the Lens Case Duo comes in six different sizes: 5, 10, 15, 20, 30 and 40. The smallest of the cases (5) is meant to hold a small prime or kit lens. On the other end of the spectrum, the biggest case (40) can hold telephoto zoom lenses, such as Canon and Nikon 70-200mm F2.8. You can find a full list of suggested carrying capacities on Think Tank Photo's announcment page. Each of the bags come in black and green colorways, feature a water-repellent coating, and have two small neoprene pouches on the front.

These bags bear a striking resemblance to Think Tank Photo's waist belt lens pouch line-up, so it's nothing new, really. The only notable difference we see is the ability to access the pouch from the side in addition to the top. Also, these don't feature a built-in rain pouch like Think Tank Photo's belt system pouches do.

The Lens Case Duo 5, 10, 15, 20, 30 and 40 are available for $21, $22, $27, $29 and $33, respectively.
