Good bag for short trips! It fits a large body (eg the Canon 5D with 17-40mm) has an average zoom (70-200mm for example) and in addition a small fixed focal length, or some accessories in the main compartment, which is easily accessible. Either quickly from above, or comfortable when it is fully open, but this does not work, if the bag is worn. The Sling-carrying method is very convenient, but the cut in the bow strap makes hanging just over his shoulder uncomfortable, you should pocket already, à la postman, diagonally across the chest, or back carry. The small lateral compartments are quite good (for pens and possibly even sunglasses), one but really very small. The small memory card slot in the "lid" is a good idea, but only for SD and too small for CF cards in the package and without the latter I do not carry my cards. The box at the front is useful for filters and similar accessories, depending on how crowded the main compartment.
