HI There
I thought I'd try shooting some surfers today with the 100-300 - at 300mm (they were a good way out, and without a wetsuit the Atlantic in May is no place to go wading brrrr!)
First of all I tried C-AF . . . not a chance - I was getting a hit rate of about 20% we all know that it doesn't work well with CDAF - I wasn't surprised.
So I thought I'd try S-AF and just mash the shutter at the critical point . . it worked just fine, the AF on the OMD is really fast, and I was getting a hit rate of about 80% - excellent (remember, this is 600mm equivalent, hand held).
Here are a couple of shots:
It was a lovely clear morning (after one lot of rain . . and before the next!)
here are a couple with the 12-50 kit lens of Gwynvor.
