Olympus m zuiko 150 400mm f 4 5 tc1 25x is pro vs panasonic 100 400mm f 4 6 3?

I don't have a page for the Panasonic 100-400mm f/4-6.3 on this site, so I can't compare the two fairly or quote its specs. What I can tell you about the Olympus is that on Micro Four Thirds it frames like 300-800mm on full frame, and f/4.5 gives roughly the depth of field of f/9 there. It's stabilised, and its built-in 1.25x teleconverter stretches it to 500mm at f/5.6.

For wildlife, I'd pair it with the OM System OM-1 Mark II if you want speed, or the lighter OM System OM-5 Mark II if you'll be carrying it all day. To work out how much reach you need, see Wildlife and sport.
