comment:The first one I tried was a retail copy with 2016 manufacturing date purchased from a local camera story. I had bought a new retail copy of the Canon EF 50 F1.8 STM at another store the day before. I won the second copy of the Sony lens on eBay with claimed damage from a sports drink. I steam cleaned this copy, and it seems to work fine now, though it still smells a bit sweet. "Made in CHINA"

This is a simple 6 element 5 group planar double gauss design like most other budget 50 mm primes including the Minolta 50 F1.7 lenses, the Canon EF 50 F1.8 lenses, and the Sony DT 50 F1.8 SAM. The rear element is an aspherical which might be an innovation in such a simple design.

The Canon EF 50 F1.8 STM is much sharper wide-open in the center, but the Sony has better edge and corner performance on full-frame. Purple fringing is pretty much absent, but there is some axial CA.

Like most E-mount lenses it uses focus-by-wire. It uses a stepper motor that functions very similarly to the Canon STM lens. Both have quite rough granularity to the focus action. It is not possible to manually focus either very precisely.

I prefer the durable plastic construction and rubber focus grip to the aluminum exterior of the E 50 F1.8 OSS. The APS-C lens is definitely a better, more complicated lens.

This lens supports the 20 FPS tracking mode on the A9 while the E 50 F1.8 OSS and Sonnar FE 55 F1.8 do not.
