Hi Trudy, thank you for looking. I don't think the 70~300 will take the TC 1.4. I don't use one and haven't tried. The lens permits great maneuverability, which is so important for butterflies and being an FX lens it gives a crop equivalent to a 450mm lens at full zoom, which is quite long enough for butterflies. It is also very sharp at f5.6 and that helps.
I used the new 80~400 G VRII fitted to a D7100 for these images.
Thanks Indrajeet for your prompt reply.
