From Canon: In response to feedback from our customers about some of our recently launched EOS and PowerShot models, Canon plans to introduce 24p mode (23.98fps) for movie recording via a series of future firmware updates for select models. After the firmware updates are downloaded it will be possible to shoot 24p (23.98fps) in 4K and Full HD for the select models.
The first models to benefit will be the EOS 90D and EOS RP at the end of October. The PowerShot G7X Mark III and G5X Mark II will follow at the end of 2019 and the EOS M6 Mark II during the first half of 2020.
Canon is committed to providing a diverse and full line-up of products, listening to our customers and providing enhancements accordingly.
