Hi folks, I have a 1Ds MKIII and am a proud owner of a brand new EF70-200L ISII lens. I purchased it from an authorized big box retailer so I am not worried that it is grey market. I noticed the lens body, when connected to the 1Ds camera body, has a little/very slight movement at the reticule. I believe the technical word of the lens part in question is the "rubber ring" contact of the lens body. See attached picture of the area in question. When I say slight movement, I mean maybe 0.5mm of play (when try to move the lens body by hand) while it is fully connected/locked into the 1Ds body. Just for comparison, my 24-70mm L lens body also has slight movement when fully connected/locked into the 1Ds body but its movement is maybe 0.25mm of play. So my question is: do you also experience this type of connectivity movement with your lens-to-camera body? Or is this abnormal. I have a feeling it's very normal, it's just that it is a little more noticeable with my 70-200mm versus my 24-70mm. Should I send it back to the retailer or send it in to Canon using the warranty?
