So this morning was my first chance to use my new EM-1 to shoot motorcycle racing. Over the years I have been shooting with a Nikon D-200 and an early 80-200 2.8 lens (cam driven focus). I was hoping that the EM-1 would be able to at least match the continuous focusing ability of this older previous set up. Well the for my first time out with it the shots were not too bad. I figured there would be a learning curve as I transitioned from optical to EVF and there was but I am getting used to it. As far as AF performance on this first round, out of the 289 shots I took about 160 were focused acceptably. Some issues were caused by me so I'm not calling Olympus out. I used the following settings for this morning's shots. AF - CAF with tracking 9 point AF Continuous drive Low set to 4 fps Stabilization off Manual exposure mode ISO 200 I found that the biggest issue with the af tracking was the that objects moving quickly away from the camera were most likely to be lost. Approaching objects seemed to do much better. This afternoon I'm thinking of turning off the AF tracking and just using CAF normal. I really try to keep the frame pretty full so I don't need to have the camera spend the extra processing time worrying about the object move across the frame. Below are a few samples.
