This "appears" to be a software, not a mechanical issue as the unit will zoom out while resting, nobody at the controls. I didn't see anything address it in the firmware update (last one in 2016). Any help or links to a solution would be greatly appreciated.&nbsp;</P> Tue, 19 Jun 2018 15:57:49 GMT https://community.usa.canon.com/t5/Camcorders/XA20-Zooming-Out-Automatically/m-p/246103#M2305 ctdennis11 2018-06-19T15:57:49Z https://community.usa.canon.com/t5/Camcorders/XA20-Zooming-Out-Automatically/m-p/278484#M2306 <P>Hi my XA30 had this issue, on researching I&nbsp; found&nbsp; out the line has an issue where they did not put the switch transducer (the sensor) in a sealed housing.&nbsp; (I run a nano-fabrication clean room).&nbsp; Try this.&nbsp; Used compressed air (a can with the small plastic tube to aim the air) into the switch to blow out dust.&nbsp; Alternatively, use a remote zoom switch (they cost between $60 and $200).&nbsp; Finally, if you are very careful, you can take off 3 body panels and clean the switch from the bottom.&nbsp; Hope this helps.</P> Sat, 03 Aug 2019 00:58:04 GMT https://community.usa.canon.com/t5/Camcorders/XA20-Zooming-Out-Automatically/m-p/278484#M2306 ContactJim 2019-08-03T00:58:04Z
