Is that the new PF fresnel version you are after? It's half the weight of the original 300 f4.
That would be the ideal but I suspect Jeff will be meaning the conventional version.
Having visited fast Nikkor 400mm + matched X2 TC on DX, I found the loss of light and difficulty of stabilising the setup wasn't a rewarding experience, everything is a compromise and long lenses with small sensors are less than ideal, OK, it CAN be done but requires much higher input with much lower returns. Some years ago I decided to stop at 300mm, if it needs more than that, I look for another subject.
