After shooting a number of airshow photos with the OMD EM1, I was already quite impressed with the C-AF potential of the camera. I then updated to Firmware 3.0 which supposedly improved upon this even further. According to Olympus "When set to C-AF, 37-point on-chip phase detection AF is used. This lets users accurately capture moving subjects so they never miss a photo opportunity." I found a terrific subject to test it out on a hot day in NYC. The results were indeed impressive as the camera achieved focus quickly, and held it throughout the burst of 6 shots.
Camera settings were C-AF, continuous LOW, single center AF point, 1/1000, f/2.8, ISO 100.
Before getting to the larger samples, I thought it would be helpful to see a grid of the whole sequence.
In these larger samples you can really see just how sharp each frame is. The camera didn't miss once, even as the subject soared towards me. I was using the Olympus 12-40mm f/2.8 Pro.
So, can the EM1 be used for sports? Absolutely! In fact, it's one of the fastest cameras I've ever used, and seems to handle action with ease.
