🐈 Canon Ef 24 70Mm F 2.8 L Ii Usm Flickr

I have a Canon 24-70 2.8 II lens, it has worked perfectly up until today. I was using my 100-400 and switched to the 24-70 and I got an Err 01 message. Normally if that happens with a lens I just wipe the contacts with my shirt and everything works again but this time it didn't work. I tried my 1 hfnCV.
