Professional photographers have unique requirements for camera bags. Firstly, a camera bag should have a large capacity to accommodate plenty of equipment. Secondly, a camera bag should be easy and convenient to use. Thirdly, a professional camera bag should meet your needs in terms of designs such as protection measures and multifunctional use.
The Manfrotto MB MA-BP-TMCA three-in-one backpack newly launched in 2014 offers distinct advantages in terms of long trips and capacity compared with single shoulder bags. Its uniqueness mainly lies in its three-in-one functionality. The whole bag can hold a large number of photographic equipment and daily belongings. Its good suspension system relieves you of excessive heaviness and you can carry it in three different ways. Its overall dimension is 25 x 25 x 43 cm, not very large, which makes it a popular choice among photographers. For a field job, I usually take more than one camera and lens, basically two cameras and 4-5 lenses, plus a laptop.
Finally, I also consider shooting in snowy or rainy days. Although waterproof, camera bags still need water pouches to protect the device inside under weather conditions such as heavy rains. This Manfrotto camera bag comes with a waterproof pouch, which is essential for outdoor trips. Though the front material of the bag is water proof, the rain pouch can provide better water resistance during outdoor trips.
