Has anybody tried that? I can't get it to do anything but focus.</P><P>However, I&nbsp;customized the button to cycle across AF methods. That is really handy.</P><P>Great lens - sharp, fast focus even in low light.</P> Wed, 21 Feb 2024 19:18:21 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463424#M29843 mdougc 2024-02-21T19:18:21Z https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463429#M29844 <P>Hi mdougc,</P><P>Can you let us know what camera your lens is connected to please?</P><P>Thanks</P> Wed, 21 Feb 2024 23:07:08 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463429#M29844 shadowsports 2024-02-21T23:07:08Z https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463473#M29847 <P>Sorry.&nbsp; EOS R5 with firmware v1.9</P> Wed, 21 Feb 2024 22:25:19 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463473#M29847 mdougc 2024-02-21T22:25:19Z https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463482#M29848 <P>Greetings,</P><P>The Control Ring on the lens can be programmed to the following functions on the R5.</P><P>Set <STRONG>AF</STRONG>&lt;<STRONG>Control</STRONG>&gt;<STRONG>MF</STRONG> switch on the lens to Control</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="shadowsports_0-1708558130373.png" style="width: 400px;"><img src="https://community.usa.canon.com/t5/image/serverpage/image-id/50163i2F2FE670115D7D34/image-size/medium?v=v2&amp;px=400" role="button" title="shadowsports_0-1708558130373.png" alt="shadowsports_0-1708558130373.png" /></span></P><P>See C.Fn3 for dial programming options</P><P><A href="https://cam.start.canon/en/C003/manual/html/UG-08_Custom_0030.html" target="_blank">Canon : Product Manual : EOS R5 : Custom Function Setting Items (start.canon)</A></P><P>Hope this helps&nbsp;<span class="lia-unicode-emoji" title=":grinning_face:">😀</span></P> Wed, 21 Feb 2024 23:41:54 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463482#M29848 shadowsports 2024-02-21T23:41:54Z https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463526#M29849 <P>Thank you!</P><P>That's all there is to it?&nbsp; So it doesn't matter how you program the button.<BR />Why don't they publish a user guide for this?<BR /><BR /></P> Thu, 22 Feb 2024 04:39:56 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463526#M29849 mdougc 2024-02-22T04:39:56Z https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463528#M29850 <P>Also, how did the subject line on my original post get changed?</P> Thu, 22 Feb 2024 04:46:56 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463528#M29850 mdougc 2024-02-22T04:46:56Z https://community.usa.canon.com/t5/EF-RF-Lenses/RF-200-800mm-How-to-set-up-dual-functionality-on-the-control/m-p/463529#M29851 <P>Not by us.
