In my experience, you need to account for the 1.5x crop factor on the FX30 or your face will look way too big. I've tried many wide lenses over the years, and the Sony E 11mm f/1.8 APS-C Wide-Angle Prime is the most logical choice. At only 181g, its perfect for walking around Tokyo all day. Plus the f/1.8 aperture is killer for night shots. Just get it and dont look back.

If youre looking to save some cash for your Tokyo trip, I've been super satisfied with the Samyang AF 12mm f/2.0 Sony E. Its basically way cheaper than the name brand glass and the image quality is honestly solid tho. Being light helps so it wont hurt your arm while vlogging all day. This leaves you with more money for ramen... you wont regret it!

Just catching up on this thread and it brings back memories. My first big trip to Osaka a few years back was a total eye-opener. I brought what I thought was a decent setup for my Sony FX30, but man, I learned the hard way about how those sensors crop in. Walking through Dotonbori trying to vlog was a nightmare cuz all you could see was my forehead. It was super frustrating... the footage looked great but the framing was just claustrophobic. I ended up having to hold my arm out so far that it started shaking by the end of the day. In my experience, weight is the biggest killer when you're walking 20k steps a day in Tokyo. Eventually I switched to a much wider, lighter setup for my daily carry. It changed everything cuz I could actually see the neon signs behind me instead of just my own face. Finding that balance between a wide field of view and something that doesn't break your wrist is the whole game... definitely dont underestimate the fatigue.
