Canon Japan has shared a pair of RF 85mm F1.2 L USM Lens sample images. Note the lack of color fringing in the white details and out of focus jewelry.
Canon USA also has a few sample pictures available. Click on the "Sample Images" link just above the "Features" section.
The Canon RF 85mm F1.2 L USM Lens is scheduled to be available in June and Amazon USA has put a date of June 20th on their product page. I don't know if that date is accurate or a complete guess, so use your discernment in that regard.
The Canon RF 85mm F1.2 L USM Lens is available for preorder at: B&H | Adorama | Amazon USA | Wex
