I just bought a new prime lens, Meike 85 mm 1,8 for my Canon m50 mark ii. It fits well with my EF M adapter but when I start the Camera a message appears: ”Push and hold the lens switch and rotate the lens to enable shooting”. It is the same message that shows as when you are using a zoom lens, but since it is a prime lens i am not able to ”unlock” it, and therefore my Camera will not let me take any pictures. I have changed the setting ”release shutter without lens” to enable, but it still does not work.
Does anyone know what i should do to be able to use the lens?
We are limited on the trouble shooting and compatibility information we can offer on non-Canon equipment. We only have information on functionality and compatibility on products manufactured by Canon. Canon does not test non-Canon accessories so we are unable to confirm whether non-Canon devices are fully compatible. For trouble shooting and compatibility information on your Meike lens we would recommend contacting the manufacturer of the device.
In general when a camera isn't communicating with a lens the first thing to check is to make sure the lens is fully secured in the adapter. If it hasn't been turned to the point where it locks onto the mount that would prevent the camera from reading it.
If that doesn't resolve the issue the next thing to try would be to attach a Canon EF or EF-S lens on the adapter to see if the same thing happens. If this is only happening with the Meike lens that indicates there is an issue with the lens that is causing it not to communicate correctly with the camera. In that case we would recommend contacting Meike. If the same issue is happening with with a Canon EF or EF-S lens that indicates there is an issue with the mount adapter. In that case we would recommend sending the adapter in for repair.

Instructions for Accessing and Using the Online Repair Portal
You will need to access or create your My Canon Account.

In order to use a lens that does not communicate with the camera, you have to enable the option to fire the shutter without a lens. However, you must be in one of the Creative Shooting modes to set this option, AND you must use the camera in one of the Creative Shooting modes.
If you switch to one of the Basic Shooting modes after enabling that option, it is possible that the setting may change in the automatic shooting modes.
Set the camera in M, manual mode, and see if it will work at all. Make sure release without lens is still active. If it doesn't work there, it is probably not going to work. It does not mean you have any problems with your camera just that the Meike 85 mm 1.8 does not like the M adapter.
A little late now but if you bought the Meike 85 mm 1.8 new, you could have bought a used Canon EF 85mm f1.8 lens that will work fully on your camera for nearly the same money.
