I had to look pretty hard to find this particular camera bag on Amazon, although the search results seem different now. There are tons of generic bags that are probably perfectly adequate but I wanted the Sony brand for my new Cybershot DSC-W350 and it was important to me to have the zipped model to completely exclude dust. The Sony bag LCS-CST (and many of the others) close with a flip-over flap with velcro closure, whereas mine has a two-way zip. Also, I chose the soft-padded model because the hard-shell types, in my experience, can eventually crack.
In short, this camera bag is all I wanted: good quality, well padded, equipped with a handy little pocket for a spare battery, and the belt loop looks sturdy. One detail that may be of interest to some is that the camera fits inside with room to spare, which for me it's a plus as it makes it easy to get the camera in and out. There are slimmer options out there but I would never carry a compact in a back pocket, so the relative bulk of this case is no problem at all, in fact I like its generous padding. The price is very reasonable for this quality and I would certainly recommend it.
