OK - another update. Got a TC 1.4EII and I have to say I am a bit disappointed with the wide open performance.

300mm f/2.8 + TC1.4EII at f/4 is definitely not as sharp as the 300mm f/2.8 at f/2.8 and is marginally not sharp enough.

The 300mm f2.8 when @ f2.8 (wide open) will be sharper than the 300mm f2.8 + 1.4x TCII is attached and shot at f4 (also wide open). This stands to reason as the 1.4x TCII does degrade the image slightly. I do not know why you would think it would be as good with the TC wide open as the 300mm f2.8 shot at f2.8 as the TC does degrade the image ever so slightly.

300mm f/2.8 + TC1.4EII at f/5.6 is plenty sharp

At f5.6 the 300mm f2.8 + 1.4x TCII combo is extremely sharp.

D800 + 300mm f2.8 + 1.4x TCII @ f5.6 ISO450, cropped about 40%:

D800 + 300mm f2.8 + 1.4x TCII @ f5.6 ISO1250, cropped about 50%:

D800 + 300mm f2.8 + 1.4x TCII @ f5.6 ISO3200, cropped about 30%:
