This Pentax branded camera bag is an in-between size. It is not a full-size bag that will take most of your camera equipment, but neither is it a camera only bag. This bag easily accomodates the rather large Pentax K10d slr with enough room for an additional modest-length lens plus a smaller type external flash gun. A moveable padded partitiion is provided to keep the camera separate within the main compartment. An adequately sized external pocket is also provided to keep such things as extra batteries and memory cards. The carry strap has a shoulder pad, which although cushions your shoulder well, is free to slide along the strap a bit too easliy and I find it to be a bit of a nuisance. Fortunately it is removed easily. You are also provided with a mobile phone holder, which is also attached to the strap and can be removed if not required. The bag is of standard quality construction, which is adequate and should provide sufficient protection from every-day bumps. The only problem I can foresee is that the bag might let in some rain if you get caught in heavy down-pour. This is due the the design of the top flap, it does not wrap over the side edges of the bag. Considering the price I'm pleased with it, it looks good and allows me to carry an extra lens a flash gun and those extra bits and pieces you always seem to need. Ideal for the hobbyist photographer.
