This is a full video showing the differences between US Milspec (Carson) vs RPO PVS-14 lenses.
One isn’t necessarily better than the other as each individual’s requirements and priorities will differ.
RPOs shave at least 74g off a binocular night vision system but at the expense of some optical trade-offs like rainbow flaring and chromatic aberrations.
DOM of the test lenses are July 2021
All footage shot on Sony A7S3 with custom lens adapter on Sony GMaster 16-35mm F/ lens
Full manual settings: 1/50s, 24fps, custom white balance, ISO 640
Footage analyzed using Adobe Premiere 2022
