I would not bother with the size and everything that fits into the pocket me. Everyone should decide for themselves. For me perfect with various Sony system cameras and some lenses. As for me - after several attempts of other Sling bags - is really thrilled that this bag is perfect for right-handers because it is behind the left arm and not as quasi all the rest of the usual offering all well-known camera bags behind the right arm. This means that you do not have to turn first to the front pocket, but you can simply reach with your right hand under his left arm and remove the camera from the appropriate side opening of the bag! The other storage options are so well thought out, that one wonders why all bags can not be so. For example, the additional waist belt in an "insertion pocket" be stored, so you really only a Sling Bag has to the no - rumbaumeln belts - just not needed. Long story short: This bag I can recommend to anyone who is traveling with system cameras or a slim DSLR. Value for money: unbeatable Ergonomics for right: perfect Workmanship: good to excellent
