I've been combining two of my favorite pastimes recently. Trail running with my dog, and nature photography.
A normal prime lens on the OMD was an easy equipment choice to make, since I had both already. Finding out that a telephoto zoom suitable for distance running exists was a bit of a surprise.
Attached are a couple pics covering the focal range. I posted some additional ones over on the landscape and nature photography forum.
Here is a link to a more detailed look at a morning in the hills over Berkeley with the Olympus 75-300mm M. zuiko.http://gerafotografija.wordpress.com/2012/12/09/field-testing-the-olympus-75-300mm-m-zuiko-lens/
The lens seems to be better at photography than I am.
