UPDATE.....Or, what I am learning about lens testing...shooting at 1/1000th on a tripod, f/45 with the 70-200 plus 2X teleconverter.... requires an ISO of 12000+
So, the first round of tests I am going to throw out and repeat with varying the shutter speed and using ISO 800 or less. The noise at 12,800 interferes with the resolution at cropping from full size down to only about 800 x 800 pixel piece of the image. That is about 4% of the full size image area. So, I will attempt some more testing, bagging the camera and tripod.
My first conclusion is, however, that at f/45 on the 70-200 and 2x teleconverter, the image is unacceptable. Yet at f/11 the results are very good at f/5.6 wide open just as good.
So, I will attempt another test this afternoon, using the VR in Active and Off so as to obtain the best results. Hopefully, some results will be forthcoming which are acceptable to me.
Another note: The 80-400mm f/4.5-5.6 is not acceptable with either the TC-14EII or TC-20EIII as it appears the rear lens element would crash into the teleconverter element a DISASTER.
