I finally pulled the trigger and got the X-S20 after years with my old X-T20 and Im blown away by the IBIS. Its a total game changer for low light. I am headed to Tokyo next month for a solo trip and really want to commit to a single prime to keep things light.

Ive always used the 18-55 kit but its time for something faster. Im torn between the 23mm f2 for the size or maybe pushing my $600 budget for an older 35mm f1.4 because I love that rendering but Im worried the AF wont keep up with the new sensor tech. Which prime is gonna give me the best results for fast street work on this body?
