received this K&F concept bag in exchange for product photography and videography, but I promise to leave my honest opinion about the camera bag here. There are some fantastic features to this bag, one of them being its versatility. The side pocket sliding out, revealing the large space, fits my Panasonic Lumix G7 with a Metabones Speedbooster and a Sigma ART 18-35mm lens safely secured in the compartment. It also contains my extra M4/3 lens, caps and a variable ND filter. That's not to mention the small battery pockets and SD card pockets on the side of the zippered bag. The battery pocket holds two batteries for my Lumix, so full SLR batteries might be a tighter fit. The bag's top compartment holds plenty of extra space, considering what has already been described as adequate. I put clothes and a laptop charging cable and a baseball glove in the overhead compartment while everything else was inside. The laptop compartment is large and fits my Dell, fitting most if not all laptops. The bag, buckles, zippers and straps are so durable so far and only one issue has come up, the side compartment piece that attaches the strap to the actual zipper came loose in my attempts to see how much gear the bag could hold. It was an easy fix, just re-bend the metal piece with pliers and the handle was back in less than five minutes. So, as a heads up, try not to pull the strap too hard if it's not coming off easily. The bag is water resistant as advertised as I used it during heavy rain days in Seattle Wa. Overall, great bag. Sleek, spacious and aware of the immediate needs of a photographer in the field, it excels at making it easy to access what you need when you need it. Looking forward to seeing more K&F Concept products.
