About this lens
The Olympus M.Zuiko Digital ED 300mm f/4 IS PRO is the system's flagship super-telephoto prime - 600mm equivalent in a lens weighing under 1.3kg, which is a fraction of what comparable reach costs in full frame. Built to PRO standards with Sync IS, it is the lens that makes Micro Four Thirds a serious wildlife and birding proposition.

Best for
For birds and wildlife this is the reason to own a Micro Four Thirds system - 600mm-equivalent reach, handholdable, and extendable to 840mm with the MC-14 or 1200mm with the MC-20 while retaining autofocus. The 1.4m minimum focus is remarkable for the focal length and makes it genuinely usable for larger insects and small subjects at close range as well as distant ones.
Frequently asked questions
How much reach does this actually give me?
The 2x crop factor of Micro Four Thirds makes it equivalent to a 600mm lens on full frame. With the MC-14 that becomes 840mm equivalent, and with the MC-20, 1200mm equivalent - while still being handholdable.
Can I handhold it?
Yes, and that is the point of the lens. At 1270g with up to 6 stops of Sync IS stabilisation, handheld shooting is normal rather than exceptional - unlike a full-frame 600mm f/4, which is several times the weight and price.
