was a little worried that this bag might not hold everything I need for a shoot, but I'm pleasantly surprised to be wrong. It's a well-made bag with plenty of padding where you need it, plenty of openings for accessing your gear, and sturdy enough to maintain its shape without any gear in the backpack. A great feature that this bag has adopted is the adjustable panels. Depending on the shoot, I can adapt this to my needs. This is great when I'm attending sporting events, like the local high school football games. I will go into this in more detail later. Let me briefly go back to the openings. One feature that I love about this bag, and I'm glad to see more bags using this, is that the main zipper is on the inside (on the shoulder straps) rather than on the outside of the bag (facing the world). For me, this is great for securing my gear while carrying the bag... I don't have to worry about someone coming from behind and trying to get into the bag. This actually leads me to my first negative, which is the side opening. This way someone can try to grab equipment and if you feel uncomfortable with that, you need to take that into account. Let's talk about size. There's LOTS of room in this thing. Remember when I talked about the soccer games in the review? Depending on the configuration of the compartments, this bag can comfortably accommodate a Sigma 60-600mm lens. For those who don't know, this lens is pretty massive. You can fit it into this thing and still have room for your camera body and a few more lenses. One feature I'm really starting to like is the adjustable size of the top pocket. The bottom slides out of the way if you need space, or depending on how you configure the bag, it can be used as a wall extender to effectively double the size of the bag. It's a great option for further customization. If there were any improvements I would recommend to the bag, it would be a place to strap a tripod. I've really enjoyed this option on other bags, and I'm disappointed that this one doesn't offer this option. Overall, this is an outstanding shortcoming of K&F. The positives far outweigh the negatives and I would recommend this bag to anyone looking for one.
