i use the 300mm f4 afs almost all the time ,i use it with the 1.7tc and find its still more than fast enough for birds in flight ,its not so much focussing time as learning to acquire target that counts ,its also a good combo for close focus pseudo-macro work .the only thing really lacking is v.r so attention to shutter speeds is needed. the lens matched with various t.c.s gives lens alone 300mm,with 1.4tc 420mm and with 1.7tc 500mm .so quiet variable and also lightweight .
