Canon RF 35mm F1.8 Macro IS STM

87% match

The everyday RF prime that also leans in

Why it wins here

The Canon RF 35mm F1.8 Macro IS STM takes this question at €550 — €2,450 under the €3,000 ceiling — with a 87% match against 65 current lenses. For one lens for a whole trip the engine leans on weight and close focus: it scores 305 g and 0.50 × mag., where the pool averages 633 g and 0.33 × mag.. At 305 g it is lighter than the average lens here (633 g). No prime-or-zoom preference was required, so the whole pool of 65 was in play.
