[Zipper] I shoot mainly landscapes but travel and sometimes architecture too. I carry one or two full-format Nikons (D750 & Df), and I wanted a bag to carry an ultra-wide zoom, a wide zoom, a 30mm, as well as a standard zoom mounted on the camera body. Sometimes I also bring a telephoto or a perspective control lens. Given the width of many of these lenses, it seems each bag I get is never quite big enough. And with heavily padded bags, the outside is incoveniently large for what it can carry. When I can be careful and need fewer lenses, I carry a lightly padded Domke bag. But Billingham's claim to offer padding that molds to the body struck me as just right--and it is. The bag is padded sufficiently but not so thickly it gets in the way. It also seems very well made. I debated between the 307 and the 335 which is nearly the same size but $$less. The biggest difference between the two is the 307 is 2 deeper--a significant difference if you want to put a body/lens on top of the gear already in the bag. The 307 also has a hinged rigid opening that makes removing lenses easier and holds the zipper away from LCD screens. The shoulder strap is wider and padded better. While I liked the exterior size of the 335 (and the sage/leather color was nice), it felt--like so many bags over the years--strained to accept the same load the 307 swallowed effortlessly. And despite the 307's plentiful room, it doesn't feel big to wear. For such similar bags, it's surprising how different their functionality is. The 307 also supports weight quite well, and it can easily hold a water bottle or two in pockets at opposite ends of the bag. It looks less like a camera bag than a piece of luggage, although, maybe the one drawback other than price, it does look like the expensive bag it is, a drawback for attracting the wrong people's attention.

[Empty] I purchased this bag to carry my FujiFilm GFX 100ii and a couple lenses. I have the bag set up so that it can hold the 100ii with both the 45-100 lens and the EVF-TL1 tilt adapter attached. I can then store the GF 55 1.7 in the slot behind the camera. Very well made and has more accessory pockets than I will ever need. Excellent quality.

[Zipper] I had to buy this elsewhere bc it was out of stock at B&H. Very pleased with it. Padding is very good with removable velco dividers, lots of pockets including one that holds an Ipad (original generation and newer models). Shoulder strap is very comfortable. I can fit a Canon 7D with battery grip and a 70-200 2.8 L series lens horizontally across the bottom and a 17-55 2.8 in one of the sleeves that come with it along with the Canon charger, lens hoods and doubler. Excellent quality and build/made to last. Expensive but worth it - I will have this bag for the next 20 years. Note that I tried 2 lowepro sling shot bags which admittedly are a different style and returned them both replacing them with this model. BUY IT. You wont be sorry

[Zipper] I needed something that would hold a Leica S and three lens plus a few other things like the Lee filter system. This bag will do all that and while it is certainly a load, I can manage it. There are larger bags that would do the job but I feel like this one 307 is made for the S with a three lens kit.

[Zipper] Weary well made. Love it.

[Empty] I bought this for my Leica SL and lenses. It fits nicely the 50 1.4; 24-90; and the 90-280 laying flat at bottom of bag and the SL itself. Excellent construction and materials. I bought this for my trip through Italy and I'm glad I did.

[Zipper] Getting ready to go on a trip in a couple weeks I thought I'd like to find me a bag light weight to create just a two lens kit to keep that weight down. �
I have owned the Billingham 207 for 4 or 5 years and when loaded down with my A7II and three lens 135 batis, FE35 1.4 and the 16-34 f4 and then miscellaneous stuff it wasn't so much heavy but more bulky.

So I just about order and ThinkTank Retrospective 5 (looks like a nice bag). Then I got to looking at the my Billingham and figured out if I remove the bottom padding I could scrunch the bag down and have what I was looking for in the ThinkTank bag (ease of use might not be quite as friendly for some).
So now when I travel I leave the bag stock before getting on a plane or whatever then once I get where I'm going I re-adjust and carry just only what I want for the day.

[Zipper] Sublime materials and construction. I use it for full frame 35mm SLR and two extra lenses, or the 35mm camera and a medium format camera.

[Empty] Wow, what an awesome bag! Built like a British Tank (a bit heavy), but well thought out and well padded. I did purchase a replacement divider (11-15 Superflex divider) so that it would fit my Rolleiflex 2.8F, but I fit it in next to the standard, included divider, and it worked out great. I'm partial to the black FiberNyte bag rather than the ligter-colored bags, even though the black bag is a dust-lint magnet. I like the bag very much!
