Nokishita 5.2mm Rumor Likely Off

Nokishita, noting an as-yet-unreleased lens cap found on a Canon accessory list, is going out on a limb and predicting that the next lens release will be an RF 5.2mm f/2.8 L lens.

This would constitute a very, very fishy fish-eye lens, especially for a full frame sensor. It would be the first time that Canon felt compelled to start noting the microns of focal length in a lens name.

This sort of focal length would be very at home as part of a duo of lenses to constitute a 360-degree camera. In fact, if indeed this is a lens designed for RF full frame, then it is quite possible it is anticipated to be used primarily as 360-degree effect camera, but with decent glass and a decent sensor.

More likely, though, is that the lens cap catalog placement was a mistake, and the product is truly intended as part of a security camera setup, where Canon and other manufacturers do indeed provide 5.2mm lenses as a conventional size.

Here is an example of a used 5.2mm lens for sale. It is called the Canon J9a.
