Previously I was using the 7D with either 135/2L or 300/4L: the focus was always pretty accurate. I would generally use centre-spot. Occasionally my target would slip out of the middle, capturing background -or- I would miss an 'in-between' frames shot. Overall the camera performed as expected and I was happy with the results.
Naturally I started to lust after the (rumoured) higher fps and AF of the 7D2, to meet the perceived shortfall. Having purchased the 7D2 I am struggling to realise the camera's potential.
I've heard of the AI Servo issues, and am having difficulty getting as many keepers as before, so I'm trying to determine if it is me or the camera.
I think I've got to grips with the various cases of AI Servo, and sometimes realise that centre spot is not appropriate, but the camera seems especially sensitive and possibly inconsistent.
Swimming is the primary subject that I am having difficulty with: What are the recommendations for AF focus points and AF case for starts and swimmers in the water? I can normally achieve 1/1000 or better, with ISO below 1600.
I am getting some superbly focussed water droplets, and out-of-focus starts. I am leaning towards a different case and focus point for the start and in-water. Does this sound sensible?
Any tips or links would be much appreciated.
