Tenba (http://www.tenba.com) has expanded its Discovery collection of lightweight professional-level camera bags with the Top Load and Photo/Laptop Messenger bags.

The Discovery Top Load (pictured) is a $69.95 carrying solution for a single DSLR camera body with a mid-size zoom lens. The $153.95 Discovery Messenger fits a larger multi-lens camera system plus a tablet or laptop computer up to 13 inches.

The Discovery Top Load enables photographers to carry their bare essentials camera kit. The bag weighs only 16 ounces, yet it will purportedly fit a professional-size DSLR camera body up to the size of a Canon 5D or Nikon D700, plus a zoom lens up to five inches long (e.g. 24-70mm f/2.8), and still offer room for extra batteries, memory cards and other important items.

The Discovery Messenger is designed for photographers who need a slightly larger camera system, but still want comfort and less weight. The bag fits a DSLR camera body with 2-3 lenses and accessories, plus a tablet or laptop up to 13 inches. In addition, it has lots of pockets, abody-hugging design, and a removable photo insert so that the bag can be converted for non-photo, general-purpose use.
