The problem doesn’t replicate its self on my 7d mkii, or my 70d.</P><P>Can anyone out there help me identify &amp; fix this issue?</P> Fri, 04 Mar 2022 04:12:02 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/EF-50mm-f-1-4/m-p/364664#M22571 bluesjb1 2022-03-04T04:12:02Z https://community.usa.canon.com/t5/EF-RF-Lenses/EF-50mm-f-1-4/m-p/364668#M22572 <P>Is the camera new to you?
