yeah, shooting long without IS/VR/OS takes practice - my 70-200 is the MK1 so all my shots are without any stabilisation and all hand held..
yeah fast jets / helicopters are all with the 70-200 with a x2 tele - i occasionally borrow a 120-300 2.8 and use that with the x2 as well..
i've had the 70-200 out in all weathers and it's yet to miss a beat
this shot was in torrential rain (not that you can see because the shutter was too slow to capture the drops of water)
