The street pancake-adjacent classic

Why it wins here

The Fujifilm XF 23mm f/2 R WR takes this question at €450 — €50 under the €500 ceiling — with a 77% match against 65 current lenses. For one lens for a whole trip the engine leans on weight and close focus: it scores 180 g and 0.13 × mag., where the pool averages 633 g and 0.33 × mag.. At 180 g it is lighter than the average lens here (633 g). Asking for a prime lens alone ruled out 37 of the 65 lenses before scoring began.
