I got my M. Zuiko 300mm f4 after shedding my EF 300mm f2.8; I don't miss the weight! First eagle to take up residence on my property also....
Tony, I have the 1.4X TC and it works well for me. How much image quality loss can I expect with a 2X TC. Your images are great, but you could make shooting with an empty bottle of beer great too...
