I was a bit 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 to access your gear, and solid enough to hold its shape without any gear in the pack.One great feature that this bag has adopted is the adjustable inserts. Depending on the shoot, I can adjust these to fit my needs. This is great for when I do sporting events, such as the local high school football games. I'll go more into that later.Let me go back to talking about the openings for a minute. One feature that I love about this bag, and I'm glad to see more bags use this, is the main zipper being located on the inside (by the shoulder straps) rather than the outside of the bag (facing the world). To me, this is great for securing my gear while I'm carrying the bag...I don't need to worry about someone coming up from behind and try to get into the bag. This actually leads me to my first negative, which is the side opening. This IS a way for someone to try and grab gear and if you feel uncomfortable with that, you will need to take that into account.Let's talk about size. There is a LOT of room in this thing. Remember when I talked about the football games earlier in the review? Based on how the compartments are configured, this bag can comfortably hold a Sigma 60-600mm lens. For those that don't know, this lens is pretty massive. You can fit it in this thing and still have room for your camera body and a couple more lenses.One feature I'm starting to really like is the adjustable size of the top pocket. The bottom moves out of the way in case you need space, or based on how you configure the bag, can be used as a wall extension to effectively double the size of that pocket. Its a great option for further customization.If there were any improvements I would recommend for the bag, it would be a place to strap a tripod. I've really enjoyed this option on other bags, and I am disappointed that this one doesn't have that option.Overall, this is an outstanding bad from K&F. The positives greatly outweigh the negatives, and I would recommend this bag to anyone looking for one.
