im looking for a bag for my DSLR. I need an ideally compact bag to accomodate a D7200 with short lens attached, 2 to 3 extra lenses, a pouch for other bits and bibs like keys and phone and a water bottle holder. The bag must also be easy to carry and quick to access. I really don’t want to spend more than £100 if possible, but I could go to £150 if it’s really worth it. Any suggestions?
