When Viltrox extended an invitation for us to check out their brand new line of lenses at this year’s Photo Plus Expo, our interest was certainly piqued. Up until this point, China-based Viltrox’s focus has been on the manufacturing of photography accessories like lens mount adapters, external monitors, speedlights, and LED lighting. We were quite eager to see how they fared with their first foray into lens manufacturing. As of right now, all of the lenses that Viltrox is working on are designed for Fujifilm and Sony mirrorless camera systems, which includes the Viltrox PFU RBMH 20mm f1.8 ASPH (Sony FE, manual only), Viltrox PFU RBMH 85mm f1.8 (Sony FE, manual only), and the Viltrox PFU RBMH 85mm f1.8 STM (Fuji X and Sony FE, autofocus). At their booth at Photo Plus, Viltrox had both the 20mm and 85mm Sony FE manual lenses as well as the Fuji X mount version of the autofocus 85mm STM lens on display, with the manual lenses being the only functional prototypes. Viltrox’s explained that the we should expect the finalized version of the autofocus Fuji lens by the end of this year, with the Sony version arriving sometime during Q1 of 2019. Due to our extremely packed schedule at Photo Plus, we only got to spend some very limited hands on time with the prototype lenses, this first impressions article will focus on the Viltrox PFU RBMH 20mm f1.8 ASPH manual focus prime lens for Sony E-Mount.
