Re: Honestly, skip the manual focus headaches for street photography. I totally agree, manual focus is a pain when you are trying to capture fast-moving life in Japan. After shooting Fuji for over a decade, I've found that having reliable glass is worth more than saving a few bucks on manual lenses. For your budget, here are two better paths:

• Fujifilm XF 14mm f/2.8 R is a legendary prime. It is sharp as a tack and the mechanical clutch for focus is actually intuitive if you ever need it.
• Sigma 10-18mm f/2.8 DC DN Contemporary is a stellar wide zoom. It is lighter and smaller than the Fuji native equivalent and that constant f/2.8 aperture makes a huge difference in low light. Personally, the Sigma is the best value right now. It covers everything you need for architecture and tight alleys without weighing your bag down.

@Reply #1 - good point! Honestly, if you want reliability without breaking the bank, check out the Viltrox AF 13mm f/1.4 XF. It blows the manual lenses away for speed and the low light performance is insane for Tokyo's neon streets at night. TL;DR: Skip the manual focus hassle, get the Viltrox for the autofocus speed and that wide aperture. You wont regret it when the sun goes down.

Congrats on the X-S20! Tokyo is a blast, but yeah, that 35mm will feel way too tight. I took the Fujifilm XF 10-24mm f/4 R OIS WR on my trip last year and honestly, I was super satisfied. Having that zoom range was a lifesaver when I was trying to capture those crowded shrines or narrow alleys without having to step back into traffic. I know the Samyang is cheaper, but having autofocus really helps when you are moving fast through the city. Plus the stabilization in the 10-24 is solid for night shots. My tip: just leave it at 10mm most of the time if you want that dramatic street look. It really opens up the frame. Whatever you pick, just enjoy the trip.

Just catching up on this thread after a long day of shooting. Before you drop cash on anything, what kind of low light shooter are you? Neon-heavy Tokyo nights eat up slower glass real fast, so aperture Sigma 16mm f/1.4 DC DN Contemporary might actually be worth looking at instead of the ultra-wides if you prefer low light over extreme width. That thing is a beast for evening street snaps. Let me know your usual shooting style and I can point you toward the right tool.

Honestly, skip the manual focus headaches for street photography. Trying to nail focus while dodging crowds in Shibuya is a nightmare. I honestly think you should grab the Fujifilm XF 16mm f/2.8 R WR instead. It is tiny, weather-sealed, and that autofocus is snappy enough for anything you will find in Tokyo. If you really need that super wide look, the Samyang 12mm f/2.0 AF is actually the way to go. It has autofocus now unlike the older versions, so you get the wide angle without the manual hassle. It is super sharp and fits that budget perfectly. Just carry a spare Wasabi Power NP-W235 Battery because those electronic lenses can be a bit hungry on long days!
