The subject is the Korean-made, Domke-inspired, David Bailey-endorsed canvas camera bag. I photographed it with a 35-70mm f/2.8 lens on a Fujifilm Finepix S3 Pro camera.
I have owned this bag for several years, having bought it on eBay for £25. I have never seen another like it, which is surprising considering that David Bailey's initials are embroidered into the fabric at the front. Maybe the bag only ever appealed to photographers whose initials were also 'DB'. The design owes a lot to the Domke F-2 bag although there are a few differences in detail, such as an all-round zip in addition to the dog-clip hardware. However, the Domke canvas is soft cotton, whereas the fabric of the David Bailey version is slightly thinner and resolutely synthetic.
