Other RF 100-300 firmware update

[David Stallard]

Firmware update for the 'beastie' (RF 100-300 2.8) on the Canon website now.

Firmware Version 1.0.6 incorporates the following enhancements:
1. Improves focus, making it more easily achievable, even when performing fast zooming operations.
2. Improves the Panning Assist control feature for 2nd and subsequent images captured during continuous shooting when using the electronic shutter.

If the lens' firmware is already Version 1.0.6, it is not necessary to update the firmware. You can check the firmware version of the lens from the camera menu. Refer to the camera instruction manual for how to check the current firmware version.

Not sure if we have anyone else here that has done the update - I found yesterday whilst trackside that I now miss focus quite a lot, it's almost like it's not 'grabbing' the point, have emailed Canon about it - not sure if it's possible to revert back to factory firmware on a lens.
If anyone knows a way I would appreciate the heads up. Thanks

After several emails with Canon - reverted to the old 'factory reset' option and after adding all the settings I could remember doing before - all seems well again, have done a full weekend trackside as well as a couple outings. That's the problem with so many options I guess, sometimes you're going to get a conflict.
