I stopped f-in about and bought an F-Stop

I have loads of camera bages - Lowepro's, peli cases, Think Tank bags - I needed a new one - none of the ones i had did what I wanted to do - i needed a bag for every day, a bag i could stuff clean under crackers in to and not take away on trips with me, but not anget the budget airline bag-size police. The F-Stop Guru 4 AIR does all of this. And the addition of the Modular day pack insert thing makes it a bag I am confident of protecting my gear - and pants. I ****** this thing, full of lenses and two mirrorless bodies around London for three days I found it comfortable and adaptable and on some of the guerilla shoots i was doing, required quick access, which the Guru AIR provided through it's pouch. I wish I had bought this bag sooner -

Great, not perfect.

I've had this for close to two months now, I am loving it, but just wish there were a few changes. 1. Not enough small pockets to put loose equipment like filters, batteries, small individual items. 2. Not sure why the 2nd layer zipper isn't waterproof like the rest of the bag. 3. Gets a little heavy on the traps after a long hike. My guess is because I toss a lot of my loose items like power banks, batteries, filters in the outermost layer, and because it's not compartmentalized, they all sink to the bottom, making it back bottom-heavy. However, just using this as an everyday camera bag, it's pretty nice, only reak urk that you can't work around is that the second layer (middle zipper) is not waterproof and water will seep through that into the second layer. Which will then seep through the internal layer separating fabrics and make both other layers damp at best, wet at worst.

A really lovely bag

Very happy with my Guru 4 AIR. The heavy-duty YKK zippers provide a smooth and reliable feel, enhancing the overall user experience. With ample pockets and compartments, organising camera accessories. The dedicated laptop sleeve comfortably accommodates my 13" Macbook Air laptop, leaving plenty of room for snacks and additional equipment. It sits really snug on my back and once tightening the straps down it doesn't bounce around like a lot of other camera bags I've used. It's definitely made for active photographers and it shows in both design and build quality. I look forward to taking it on some hikes and probably even overseas for a daily carry when shooting street photography.
