If so then increasing the f# won't give you a tighter FOV.
You need more FL.
Unfortunately a teleconverter won't fit on the 75-300mm.

you are quite right.... but a teleconverter will give more magnification, but at the scarifice of f#... i think a 2x tc will drop his lens back 2 stops... therefore making it no longer a f1.7
