Perfect little bag for my Sony Alpha 5000: between the hair! A fair bit in terms of space for a backup battery. I found a small external pocket for SD cards and essential equipment cleaning. Probably the battery? A try. The charger comes in forcing a little bit, so not to do. Anyway, it is rare to travel (distance or not) without backpack :) One can easily find the spot or in a jacket pocket etc. The velcro closure is a little noisy, but probably much stronger than a zipper Magnetic would be an option if it was slightly more spacious. Beautiful item for the price.
