I recently updated my 1.4x extender to the mk3 however the mk3 doesn't always work on my 500mm F4L (mk1). There is a little play/movement between the lens and the extender or camera body if no extender used but all has been working fine, until the mk3 1.4x.
When the camera and extender are moved to the right of the area of 'play' all is fine but when the camera/extender move to the left there is a failed connectivity, often resulting in an error message. The level of play/movement is extremely minor.
When I use the bare lens or back with my old 1.4x mkii this problem does not occur, its only with the mk3 extender.
The new extender was bought at the end of April and has had very little use in 3 months since I got it..
As the bare lens/body and lens/body/old 1.4x extender combo work perfectly fine this would appear to be an issue with the mkiii extender.
Has anyone else experienced any issues such as this or could it be a compatibility issue between older lens and newer extender?
