The bag is super for this price. My camera (Sony Alpha 57) fits with attached 18-70mm kit lens Sony Tamron 70-300mm next to a grade into so. Then everything is tight in there, so that nothing can shake or flying around. The subjects can be very good use of the charger, replacement battery, lens cap and other small items.
The battery is that it came with this bag absolutely OK. He holds by no 500 pictures, but about 300 images, there are still. Always to use as a replacement battery.
The length of the strap, I feel, to be quite large and powerfully built person, to be sufficient. I can carry the bag across her shoulder and had enough room.
