The bag is meticulously crafted and comfortable to wear, even if the generous shoulder pads at first is still very stiff. I use the pocket for housing and transporting my system camera equipment. With skillful arrangement of the splitter fit Fuji XE-1 and the lenses 18 mm, 35 mm, 18-55 mm, adapter and power cord, Fuji Flash EF-20 with 4 spare batteries, Yongnuo RF-602 plus Canon-plug cable as a wireless remote shutter release, as well as small parts such as memory cards, camera batteries, data cables. In all of this there's room for another, longer lens such as the Fuji-X 55-200mm or the Fuji X 56 mm, both but not yet available. The positioning of the clip closure under the top flap of the bag has proved to be impractical for me. I have therefore separated the inside sewn portion of the closure and sewn on the outside at the same position. This requires patience and special sewing kit, one can at a pinch but can also make the Sattler. If you want or need to calculate the available storage space in advance exactly, should note that the bag is slightly trapezoidal and on the ground about 3 cm shorter than indicated.
