This photo pack is great in both functionality and versatility of use. Although I purchased it for my photography hobby I am not the owner of enough lenses and accessories to utilize the many compartments designed for lenses of various sizes. The compartments can double for other tech accessories/equipment such as navigation devices, smartphones, certain tablets, etc. If you happen to be of a higher level of photographer there are spaces that will fit all types of photo equipment. Compared to the more expensive and inferiorly designed competitor's packs this is a great option for photographers of all skill levels.
