lense adaptor not working | R7 with EF-EOSR

[ebucky]

I have a brand new Canon R7 and have bought a third party EF-EOS R adaptor (from K&F Concept) for my EFS lenses. 

I am unable to take any photos and I'm not sure if it's a problem with the camera or the lense adaptor??

Help please!!

Since Canon EF and EF-S lenses work fine with the Canon Adapter, it is probably your third party one.

I agree.  All third party adapter were taken off store shelves because it was becoming apparent that most customers were reporting camera issues when they were using them .

Another question I have would be what lens are you using?

First and foremost, the first thing to do is replace any third-party device, especially an adapter, with genuine Canon components.  Like every other OEM, Canon will not, because they cannot, support third-party components.  If you want to get support and avoid breaching your warranty, it is better to use OEM components.

If you can't afford to purchase one, see if you can borrow one, if only to attach one of  your lenses and try to see if it focuses - if you are having issues with multiple lenses, it makes it fairly likely that there no issues with the glass.
