A friend asked me to recommend a photography bag for commuting. It should be simple and elegant. In addition to the camera, it should also be able to fit a laptop or iPad or mobile phone. Also put a thin quick-drying coat, which is as small as an egg when folded. I recommend Billingham Hadley Pro because I have been using it for more than ten years and it has worn out, but I trust it very much and will continue to use it. It has a certain waterproof effect and has a large storage space. The most valuable thing is that I can quickly take the camera out of the bag and I am already familiar with it.
