I own a EM 5 mark 2 and am interested in purchasing a super zoom lens for bird and wildlife photography. Currently I'm considering the Oly 75-300mm and Panasonic 100-300mm, which both fit my budget. The former is cheaper, but lacks a hood and is a half a stop slower than the pany, which comes with a hood. I've read a number of reviews on both lenses, but am still undecided. I'd appreciate some feedback regarding people's experiences of both lenses on Olympus bodies.
