I4ani pointed to one on Nikongear.com used on a 300/2.8vr the example posted look very good indeed, it was under forums and lenses
I don't know anything about the TC 20 E III but here are some links I came across.

I hope this helps.
Thanks Steve, though I've since discovered on the Nikon site that it doesn't AF when coupled with the 300f4 AF-S. Not sure £400+ can really be justified without AF!
Looks like I'll have to plump for the 1.4 which many say is a good combo with the f4.

I'd love to know how it performs on your 500mmf4 too Neil.
looks very acceptable, mind you the noise management of the D3 may help a tad, do you have a D300 that you could try with it (especially with the 500/4)
Look forward to some more examples
