Canon EOS M and EF-M 11-22mm IS STM Issue (with firmware 2.0.2)

EF-M 11-22mm f/4-5.6 IS STM Review

A Canon Watch reader (thanks MdB) wrote me an email reporting a strange issue he and another user are having with the Canon EOS M and the EF-M 11-22mm f/4-5.6 IS STM lens. MdB writes:

The problem: If you turn the camera on whilst the lens is already extended the M will not fire off a shot at all. If you turn the camera on and then extend the lens it works perfectly fine. If you turn the camera on with the lens already extended you have to retract the lens and then re-extend the lens and the camera will start shooting again.

The issue appears to show up even with the latest firmware (2.0.2). I tested this on my EOS M and the 11-22mm and could not replicate it.

Does someone here experience the same issue? Would be glad if you can post it in the comments. Thank you.

    I’ve tried this on my 11-22mm from HK and don’t have a problem with firmware 2.0.2. The previous firmware was not tested on my camera with this lens, however. My camera was purchased in the USA if it matters.

    I’ve never experienced that problem and can’t replicate it either. I’m using a USA M and a Canadian 11-22mm with 2.0.2 in english.

    tried it on my two EOS-M’s .. couldn’t replicate here either.

  • Lawrence

    Never had this problem. Can’t reproduce it.

  • Stefano

    I’ve had the M with the 11-22 for a couple of weeks now, but I’ve never experienced that problem. I usually put the camera in its bag with the lens in the extended position.
    M and lens bought in Italy, firmware 2.0.2

    If I recall correctly I’ve seen this. It’s a leftover from Magic Lantern…, do a complete Magic Lantern uninstall, (unset bootflag) and do a full factory of all settings. If that still doesn’t work, re-flash 2.0.2 again. And it will work correctly again.
