Review on Samyang AF 85mm F1.4 Weather Sealed Lens - Canon EOS R RF Mount (SYIO85AF-RF): High-Speed Auto Focus Lens for Clear and Crisp Photography by Will Aesthetics

Integrated image stabilization with R5/R6 is available in firmware version 3. Be sure to ask. Otherwise, you'll need a Lens Station to upgrade, which costs $60. Or send it to New York City Customer Service for $20 return shipping. Pros: 1. Image distortion, also known as pincushion, is very low.2. Fast and somewhat quiet focusing. This is an ultrasonic motor that's fairly quiet and as fast as Canon RF lenses. But when focusing, it makes a faint click. Don't bother me.3. The sharpness in the middle is good. A smaller aperture also improves angles. Cons: 1. No IP. Although I don't see an 85mm 1.4 with IS. Just think of zoom.2. There is no lens correction data on the camera. Which leads to the biggest problem: 3. Heavy vignette effect. I'm very serious at 1.4. Not only brightness, but also size. I gave 4 stars because of the price. Given the large aperture, autofocus and central sharpness. It's a damn good portrait lens.
