Yes, it's a lifelong journey. But if you accept that, you'll start to recognize that the journey itself is more rewarding than the presumed destination. I'm not referring to just the technical aspect, but learning to see. And that's where many photographers get derailed. They're in such a hurry to get from point A to point B that they bypass the most essential aspect - actually seeing things. Big camera help by slowing us down and making us take a deeper look. But I'm not a ULF photographer myself. I mostly enlarge rather than contact print, and do it in both color and black and white, so 8x10 is the largest format convenient for me. A number of current ULF shooters also have cabinet shop skills and make their own cameras; and for lenses they frequently employ graphics barrel lenses due to not only the wider range of focal lengths available, but also the optical properties, which are generally superior to regular taking lenses, and the more favorable pricing on the used market. A good ULF hauler could be jerry-rigged from a game-carrying frame (like for elk or deer). The companies that make those can make customized packs too. But for my own needs, just up to 8x10, I prefer classic US made 70's vintage external frame packs from Kelty, Camp Trails, etc (not the newer import stuff, which is inferior). Although these packs were expensive new, they often turn up in people's closets or garages totally unused all these decades later. I once traded a half-empty quart of varnish for an unused one at a local yard sale. But don't expect to find spare parts. That's why having extra packs to cannibalize helps, now that they sell so cheap. I have carbon fiber tripods for long-distance trips, but otherwise prefer Ries wooden tripods. I never use a tripod head, but bolt the camera right to the platform top of the tripod, just like a surveyor would do with a modern theodolite or old transit. After a little practice, adjusting things using legs only becomes fast and instinctive. My 8x10 is an early Phillips, serial number nine!. Chamonix and several other companies have copied this simplified design. Keith Canham is a great guy. In my opinion, the sweet spot in his line is the 5X7 wooden folder; but I'd want a little more support on the front standard to his bigger cameras. I do have a 4x5 Ebony folder. They were the most precisely made wooden cameras ever, worthy of their high price. But there are still plenty of other good choices. ... Don't confuse the rendering characteristics of 35mm brands in relation to the much wider range of lenses available for view camera use. I kinda like the flatter rendering of my classic Nikkor 85/1.4 Ais for black and white film, though if I still shot color slides, I'd probably prefer the Cosina-Zeiss 85/1.4. Don't transfer that to view camera lens characteristics. Most of the hyper-crisp late view camera lenses, regardless of brand, don't have particularly flattering background bokeh, but characteristics often desirable for landscape and commercial photography. So you might want to think of a wholly different set of lenses for portraiture, where too much crispness or contrast might be a disadvantage. The 4.5 Ektars or similar lenses from Zeiss won't be as sharp as truly modern lenses, but are apt to give you a more classic rendering with portraits, if you are interesting in that kind of photography. But I have an old single-coated Zeiss f/9 graphics tessar that does a lovely job and was dramatically cheaper to acquire. You really don't need a lot of lenses overall if your choices are good to begin with. Portraiture doesn't require a lot of excess image circle either, whereas the strong tilts and swing of landscape photos, and significant rise of architectural shots, often do. And you're completely wrong about Fuji. They are absolutely equal to German lenses, and often better, with niche types other companies don't provide. They're even a bigger company. Their view lenses might have been under-marketed in this country, but everyone who uses them knows about their high quality. No general purpose plastmat is equal to the "super-plastmat" Fuji A series, though they have smaller maximum apertures. Fuji also makes some of the very best, most expensive video lenses. So back to ULF and your question about a 19" and 24" - I'd point you straight to the Fuji 450 and 600's, depending on just how large you mean by ULF. Longer than that and you're going to have to select from Apo-Nikkors, Apo Artars, etc, re-purposed graphics barrel lenses. A different forum, the Large Format Forum, which many here also belong to, has lots and lots of more specific answers.
