This Sony branded bag is the perfect size to take the NEX:5 as well as a spare lens, memory cards and batteries, all without unduly compromising the weight of the camera and the space it needs in luggage.
It is well made and constructed of black textured fabric, which is well padded around all sides and the bottom although strangely not the top. The bag incorporates a strap that is adjustable to cover most requirements for neck/slung around shoulder carrying, or there are two belt loops should that be your preferred choice.
There are two small, external side pockets that can hold a battery each or several memory cards, as well as a larger zipped compartment at the front that would allow a few other bits and pieces to be carried.
The main compartment accommodated the camera body with the 18-55 lens attached and enough space to fit a second lens alongside. Alternatively the camera with 18-200 lens fits comfortably but you won't then have room for a second lens. A padded divider is included in this section to help separate and thus protect the contents; it fixes with Velcro so can be moved to suit your choice of contents..
If you are looking for a bag in which to carry the NEX-5 then this is worth consideration. I have awarded four stars only because of the lack of padding at the top of the bag, it is otherwise perfect.
