Nano USM first saw the light of day in 2016 on the entry-level Canon EF-S 18–135mm f/3.5–5.6 IS lens. More recently, Canon has successfully implemented it on the EF 70-300mm f/4-5.6 IS II USM. Now, with the RF 24-105mm f/4L IS USM, the technology has matured enough for the company to include it in their L lens lineup.
In the final analysis, I am of the opinion that the Canon 24-105mm f/4L USM II does what it is designed to do. My hit rate was almost 50%. But I think it would have been better, if I shot with less megapixels, given that the sample images look much better down sampled for web viewing. Off to Shuttleworth vintage air display. 33.
