Lens wiggle issue
I recently noticed a wiggle/play when I use TC-14e and/or 70-200 f2.8 VRII. Each has about 1-2 mm rotational play. It becomes a bigger issue when both are used at the same time. I tried this on a D800 and D90 and I see the same problem. This issue does not show on other lenses (50mm f1.8, 105 F2.8 VR).
My main concerns are around the problem becoming getting worse and having CPU connector contact issues, and also the misalignment of horizon when I use the combo on tripod (I guess I can post-process it, but rather not deal with this).
I still have a few days to return/exchange these. I wanted get your input on if this is a common occurrence that i should just accept it. It still does not feel right to have such poor tolerances on such expensive equipment...
