Mantona PRO NOVO SLR Camera Bag Colt compact bag black (with lap belt, Gurttunnel) for, for example - Canon EOS 70D 60D 600D 650D 700D 1100D 1200D - Nikon D610 D3100 D3200 D3300 D5200 D5300 D5500 - Sony SLT A58 A3000 (and many more, see product details) (Electronics)
Who has only one lens and this will have, is well served with this bag. The bag is well thought out, to me is so far no technical or any function really come off. My 18-105mm lens together with Nikon D3300 fits loosely into it, even with mounted lens
