Olympus OM 300m f/4.5 Lens Review
Rare excellent lens, super sharp even at wide open to compare with much more expensive lenses hard to see any quality differences.Very well built as all Olympus OM lenses. It has tripod mount and built-in lens hood. I found viewfinder bit darker with this lens than with Nikon Nikkor 300mm f4.5 ED IF.Lens does not rotate during focusing which is good for using polarizers,almost half the weight of the current AF 300mm f4 from Canon and Nikon, but still not light weight than Nikkor 300mm f4.5 ED IF.Perfect choice for any Olympus or Canon owner works just fine with suitable adapters.The compact styling and superior performance makes this ZUlKO 300mm an ideal tele-lense for sports, wild life even when it is handheld. The lense has a larger filter attachment size which accepts any 72mm threaded filter and usable with Tele-converter1.4X-A.

(Shin) Yoshina, the nature photographer, ... The photos of birds that made him famous were shot with his favorite Zuiko 300mm. It is said that he shot most of them with open aperture."

A magnificent super telephoto lens

(Olaf Greve)

Relatively cheap tele with decent performance.
