Good image quality, especially on 300mm lens

Just hv 1 on hand, run a rough test on the gears from friends, The new converter works great on the 300mm Nikkor, it\'s outstanding even wide open,
half to 1 stop stopped down then the result is amazing. Also it gives acceptable image quality on 600mm Nikkor when stop down to F/11.
and it looks F/11 is the best F stop so.
I see no advantage when stopping down more......
The AF speed just slightly different on 300mm,
And slightly slower on the 600mm.
When attached TC 20E then 14E, the 600mm
will no lock on anything just keeping focusing....n Haven\'t try 2 converters on 300mm yet....
