A new patent filed by Canon Japan shows multiple optical formulas for an RF 50mm f/1.4 and f/1.8 design as well as a new RF 35mm f/1.4. The patents deal with increasing focusing speed when using lenses with large diameter elements.
Yongnuo has unveiled a new 50mm f/1.8 lens, expanding its "nifty fifty" lineup to include the YN50mm f/1.8S DA DSM for Sony's E-Mount APS-C cameras. We don't have a price yet, but we expect this to be the cheapest 50mm lens you can buy for Sony's a6000 series once it hits stores.
A reliable report from Canon Rumors, as well as a newly discovered patent, has revealed some of Canon's exciting plans for the RF Mount. Not only is a nifty fifty 50mm f/1.8 lens in the works, the company is also working on a pancake lens and has designed a 135mm f/1.4L.
Canon's 50mm lens lineup is getting crowded... at least that's what Canon seems to think. According to a fresh rumor, the company has plans to replace the current 50mm f/1.4 USM. But it won't be replaced by another f/1.4. Instead, Canon might do away with the lens altogether and release a high-end 50mm f/1.8 IS USM instead.
