SUMMARY
Toms Jurjaks compares the 7Artisans 135mm f/1.8 and Viltrox 135mm lenses, highlighting a trade-off between the Viltrox's raw optical and autofocus performance and the 7Artisans' lighter, more affordable package. While the Viltrox is sharper at f/1.8, the 7Artisans matches it when stopped down and offers a preferred tactile aperture ring for portraits. The 7Artisans lens is also lighter and features improved packaging, though its STM autofocus struggles with fast-moving subjects compared to the Viltrox's VCM system.
