Olympus Four Thirds telephoto with 600mm equivalent and ED glass, works on MFT via adapter at budget pricing.
The Olympus Zuiko Digital ED 70-300mm f/4-5.6 is a telephoto zoom for the Four Thirds DSLR system covering 140-600mm equivalent with ED glass. The 2x crop factor provides extraordinary equivalent reach from a manageable focal length range.
The 140-600mm equivalent provides genuine super-telephoto capability on Four Thirds sensors, and the ED glass controls chromatic aberration at the longer focal lengths. The lens was designed specifically for digital sensors with optimised optical formulas.
Build quality is quality Olympus Four Thirds with the construction expected for telephoto lenses. The lens works on MFT bodies via the MMF adapter, though AF performance via adapter is slower than native Four Thirds bodies.
The Zuiko Digital 70-300mm ED offers 600mm equivalent reach at affordable used pricing. The Four Thirds-to-MFT adapter compatibility extends its usefulness to the modern MFT mirrorless system.
