The first one is an RF f/2.8 Pancake lens, which is definitely in the works and is expected to be announced sometime in the first half of 2020. Maybe it will have the same design as the current EF 40mm f/2.8 pancake lens.
The second one is the RF 50mm f/1.8 lens, just like the EF 50mm f/1.8 STM lens for Canon EF mount. The exact announcement date is still unknown.
Stay tuned for more info.
