Overview

The Viltrox AF 135mm F1.8 LAB offers outstanding optical performance with minimal distortion and moderate vignetting. Its build is excellent, using high-quality plastics and magnesium alloy, but it is heavy at 1.3 kg. Autofocus is silent and reasonably fast via HyperVCM, though not sports-fast. Weaknesses include an unmarked aperture ring that can be imprecise and the lack of a tripod collar. It suits portrait and still-life photographers seeking near-optical perfection at a competitive $899 price, provided they can tolerate its size and weight.
