One reason that I wanted to start with the 600 mm f/4 lens is that after extension I will still only be at an effective f-stop of f/8 at 1X. The big process lenses are typically f/9 to start with which will take me to f/18 effective so I worry about diffraction. That said, I bought a 610mm apo nikk...

Wandering Mestra egg
