Review

In terms of video quality, Canon's 4K footage, which uses the entire width of the sensor, looks a bit soft, especially when compared to the Sony a6400's oversampled 4K. The 90D's 4K footage also looks significantly less detailed than that of the Nikon D7500 and the Fujifilm X-T30.

Look! Beast is alive!

Canon will add 24p video modes to 90D, both in 1080p and 4K.

Release in late October.

PR considering post above

In response to customer feedback about the recently launched EOS and PowerShot models, Canon Europe will introduce 24p (23.98fps) mode for video recording, via a series of future firmware updates for select models. Once downloaded, the free firmware updates will enable users to shoot 24p (23.98fps) in Full HD and 4K resolutions for the select models.

The first Canon models to benefit from the new 24p (23.98fps) firmware will be the recently launched EOS 90D and EOS RP in late October. The Canon PowerShot G7 X Mark III and G5 X Mark II will follow by the end of December and the EOS M6 Mark II update will be available during 2020.

This announcement comes after the recent availability of the new firmware version 1.3 for EOS RP and 1.4 for EOS R which further enhances the eye and subject detection AF performance of both mirrorless cameras. Canon is committed to providing a diverse and full line-up of products to cater for all capabilities and interests by listening to our customers feedback and providing enhancements accordingly.
