I have it in manual mode. I have AF turned off.</P> Sat, 30 May 2020 19:51:19 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-M10-500mm-telephoto-lens/m-p/308288#M72703 Ladylynn 2020-05-30T19:51:19Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-M10-500mm-telephoto-lens/m-p/308328#M72704 <P>The camera thinks that there is no lens attached to it. &nbsp;There is a menu setting that you have to enable to allow the shutter to release without a lens attached.</P> Sun, 31 May 2020 11:59:15 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-M10-500mm-telephoto-lens/m-p/308328#M72704 Waddizzle 2020-05-31T11:59:15Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-M10-500mm-telephoto-lens/m-p/308356#M72705 Took me awhile to find the setting.
