I asked OMDS if I could call in another lens for testing and photographing birds, so they sent me the Olympus 100-400mm f5-6.3 PRO lens. Indeed, this is a much better choice for photographing birds in the wild and even in cities like where I live. Where this got particularly fascinating is with a head to head test I did against the Sony a1 and Canon EOS R5.
