Questions about Sigma 16mm / f 1.4 DC DN C Canon EF-M

I don't know what's wrong with me.... I've already answered the question for the second time, NO this is for the M series, no EF connection.

According to the manufacturer, it is not compatible with the EOS 250D. This lens has an EF-M bayonet and the camera has an EF-S bayonet. We do not currently have any suitable adapters in our range.

Yes

No, that does not fit at all. The lens does not have an EF mount, but an EF-M mount for Canon's (effectively dead) mirrorless APS-C system. There is no adapter to RF and that makes no sense. Buy an RF mount lens for the RP.

If by "MF" manual focus is meant. Of course, the lens can also be focused manually after the camera has been set to the corresponding mode. However, there is no switch on the lens for this.

No that is not possible. However, there is an mFT version of the same lens. That fits. This one is for EF-M.

Not a stupid question :) It fits the Canon M50, even without an adapter. It's a cool lens, have fun with it!
