Curious about one thing: are you mostly on a tripod doing straight-on interior stuff, or more handheld tight streets? I ask cuz I’ve had waaay diff results depending on that.

In my own setup, what mattered most for *reliable* architecture shots was:
- how clean the corners get at f/5.6–8
- how sane the distortion correction is (some get wierd “wavy” lines)
- flare control when a window’s in-frame

Also—do you need WR for real rain/dust, or just “peace of mind”?? I feel u, been there lol

Oh man, been there… first time I tried shooting a tight interior on Fuji X I came home like “why are my corners doing THAT??” lol. Over the years (and way too many test shots of brick walls…), the ultrawide that’s felt the most “architecture-safe” under your $900-ish cap is Fujifilm XF 10-24mm f/4 R OIS WR. It’s not the flashiest lens, but honestly it’s the one I trust for straight lines + usable corners. Stop it down to like f/5.6–f/8 and the corners clean up realy nicely, distortion is there but predictable and easy to fix, and the WR is a legit bonus for city shooting.

If you want the “sharpness per dollar” alternative and don’t mind losing weather sealing, I’d look at Sigma 10-18mm f/2.8 DC DN Contemporary (Fujifilm X Mount). It’s usually cheaper, surprisingly sharp, and f/2.8 is nice for handheld interiors… BUT the edges/corners can be a little more hit-or-miss depending on distance and how picky you are.

And if you find a deal used, Tokina atx-m 11-18mm f/2.8 X is another solid budget-ish play, just expect more distortion work.

Lesson learned for architecture: don’t chase only “wide” — chase corners + distortion behavior. That’s what saves your sanity. gl!

TL;DR: I’d grab the Fujifilm XF 10-24mm f/4 R OIS WR.

For your situation, it’s the best “architecture-safe” ultrawide I’ve used on X—sharp corners stopped down, distortion is super manageable in post, and the WR is a realy nice bonus for street stuff. Used it’s often under $900. If you can live without WR, Fujifilm XF 10-24mm f/4 R OIS is usually cheaper and still fantastic. gl!

Like someone mentioned, the zoom is the safe bet, but I'm gonna go against the grain here. I've found that zooms can be a bit of a trap for architecture because of that digital stretching. If you're trying to keep costs down but quality up, I would suggest looking at a few primes that I've used:

• Viltrox AF 13mm f/1.4 XF: This is my current favorite for interiors. It's crazy sharp and fast for the price, though you might want to consider the size since it's kinda chunky.
• Fujifilm XF 14mm f/2.8 R: Tbh, if you can find this used, jump on it. It has basically zero distortion and the pull-back focus ring is a lifesaver for manual work.
• Samyang 12mm f/2.0 NCS CS: Super cheap and surprisingly sharp. Just make sure to double check your focus since it's fully manual, it can be tricky. I really think you'll get better corner performance with these than the zoom, and they're way under your budget. Just my two cents... good luck with the search!

So looking at the consensus here, it seems like most of you are sticking with the standard zoom options for the sake of reliable lines and that WR peace of mind, though there's definitely some debate on whether those corners actually hold up when you're shooting wide open. I’ve spent way too much time obsessing over the technical fitment of these things, and I’ve learned a few things the hard way regarding compatibility: - Electronic communication is basically non-negotiable for me now. I used a lens for a while that didn't talk to the body, and trying to manually correct those 'wavy' architecture lines without an embedded profile was a total time sink.
- Mount tolerances are huge. I had one setup where the flange distance felt just a hair off, which basically killed my corner sharpness on one side because the sensor wasn't perfectly parallel to the rear element.
- Sensor stack issues: Some ultra-wides (especially older or adapted ones) just don't play nice with the glass over the Fuji sensors, leading to weird color shifts or smearing that you just can't fix in post. Basically, even if a lens is technically "compatible," how it actually communicates with the camera's software makes a world of difference for architectural work. Honestly, I'd suggest checking if the one you get has full electronic integration because those automated corrections save so much headache...

Just saw this thread and wanted to offer a slightly different take. While the 10-24 zoom is the standard choice, I find primes often give me cleaner results for serious architecture work. Zooms tend to rely a lot on digital correction which can soften those corners you're worried about. Here are a few that might serve you better:

• Laowa 9mm f/2.8 Zero-D
• The Zero-D stands for zero distortion. Its manual focus, but for architecture on a tripod, thats rarely an issue.
• Fujifilm XF 14mm f/2.8 R
• This is one of Fuji's best-corrected lenses. The lines are naturally straight without needing much help in post.
• Samyang AF 12mm f/2.0 Fujifilm X
• This one actually has weather sealing and is very sharp for the price point. Quick tip: Try shooting slightly wider than you need and cropping in. It helps avoid using the very extreme corners where even the best lenses start to lose a bit of resolution. Just make sure your camera is perfectly level to minimize perspective distortion from the jump.

Same here!

> Re: "Like someone mentioned, the zoom is the safe..." Spot on! Primes definitely win when you are looking at the raw optical throughput without the heavy-handed software corrections that most modern zooms rely on. When you analyze the MTF charts, the way the resolution holds up in the extreme corners is just fantastic on a solid prime. I remember doing a technical shoot for a heritage site last summer, focusing specifically on the stone masonry details. It was incredible work, but the light was just perfect that day. It actually reminds me of this time I drove three hours out to this abandoned grain silo in the middle of nowhere just to get one specific shot of a spiral staircase. I forgot my tripod plate in the car and had to hike all the way back through a field of literal thorns! I ended up getting a flat tire on the way home too, and the tow truck driver was this super eccentric guy who collected vintage film cameras. We talked for like two hours about the mechanical shutter feel on old gear while he towed my car. Honestly, those old mechanisms are just art in themselves. Anyway lol, sorry kinda went off topic there.

Any updates on this?
