Think Tank Photo has just debuted a new set of Spectral shoulder bags: the Spectral 8, Spectral 10, and Spectral 15. All three camera bags are designed to give photographers an inconspicuous way to carry around their camera gear, helping protect their equipment from both unsavory environmental conditions and thieves.

The bags feature a Fidlock magnetic clasp that allows users to access their camera gear with one hand and automatically locks when the flap is closed. The Spectral bags also feature an extra zippered closure that Think Tank says 'can be tucked away when actively shooting.'

All three bags are made with 420D velocity nylon, heavy-duty nylon tarpaulin, YKK RC Fuse zippers, 350G 3D air mesh, antique plated metal hardware, and 3-ply bonded nylon thread.

All three bags contain a tablet compartment—the Spectral 8 can accommodate a tablet measuring up to 8", while the other two can handle tablets ranging up to 10"—and a dedicated smartphone pocket. There are also straps and attachment points for a tripod, a pass-through slot for a luggage handle, internal pockets for small items like card wallets and batteries, plus a seam-sealed rain cover for protecting the bag's contents.

In addition, the Spectral 15 model has a compartment for a laptop measuring up to 15-inches.

The Spectral 8, the smallest of the three bags, has enough room to accommodate a single standard-sized DSLR body plus a detached 24–70mm F2.8 lens, one attached short zoom or wide lens, plus a couple small lenses or one additional larger lens. The Spectral 10 is similar, although it boasts room for up to three extra lenses plus a detached 70-200mm lens and an attached 24-70mm lens. The largest of the bunch, meanwhile, can accommodate the same, but with up to four additional lenses, plus a tablet and a laptop at the same time.

All three bags are available from Think Tank now for $100, $120 and $140 for the Spectral 8, Spectral 10 and Spectral 10, respectively.
