The engine's answer

Best zoom lens for street and travel, under €3,000

Sigma 18-50mm F2.8 DC DN

94% match

A constant f/2.8 that fits in a coat pocket

Why it wins here

The Sigma 18-50mm F2.8 DC DN takes this question at €450 — €2,550 under the €3,000 ceiling — with a 94% match against 65 current lenses. For street and travel the engine leans on weight and max aperture: it scores 290 g and f/2.8, where the pool averages 633 g and f/3. At 290 g it is lighter than the average lens here (633 g). Asking for a zoom lens alone ruled out 28 of the 65 lenses before scoring began.
