Scott Bourne posted the full Bird Photography Gear Guide for Micro Four Thirds Shooters:
I am thrilled with the results I get from this gear and very thankful to the engineers who created the Micro Four Thirds format. Without it, my shooting career might be over. Thankfully, I don’t feel like I’ve had to compromise at all to make this switch and in fact, feel like I’ve gotten better images as a result. If you are interested in this gear don’t worry, it’s more than capable if you are.
