The Thinktank Digital Holster 20 is a mid-sized padded holster-style case for a DSLR and professional lens. This is not a full kit bag- there's room for the camera and lens only- but it's good protection for a bit of working equipment. Expandable bottom makes this suitable for most "reasonable" pro lenses (for example, a 70-200mm f2.8.) In excellent condition, with shoulder strap. This bag tapers towards the bottom, but interior dimensions at the widest point are approximately 11x18x21 (or 11x18x30cm with the bottom expanded)
