Lens Overview — Olympus Zuiko Digital ED 70-300mm f/4-5.6
Key Features — Olympus Zuiko Digital ED 70-300mm f/4-5.6
70-300mm Four Thirds Zoom: Covers a wide telephoto-to-long telephoto range on the Four Thirds mount, delivering an equivalent field of view of 140-600mm in 35mm terms.
f/4-5.6 Variable Aperture: Opens to f/4 at the wide end, giving slightly more light-gathering capability during mid-range telephoto shooting.
ED Glass Elements: Extra-low Dispersion glass helps reduce chromatic aberration and colour fringing across the full zoom range.
EC-14 Teleconverter Compatible: Accepts the Olympus EC-14 teleconverter to extend effective reach to 425mm, though with a resulting aperture of f/8 and some image quality trade-off.
Close Focus Advantage: Offers a shorter minimum focusing distance than the 75-300mm alternative, making it more useful for closer telephoto subjects.
Lightweight Build: Notably lighter than most other Four Thirds lenses, making handheld telephoto shooting more practical for extended use.
Description — Olympus Zuiko Digital ED 70-300mm f/4-5.6
The Olympus Zuiko Digital ED 70-300mm f/4-5.6 is a telephoto zoom lens for the Four Thirds (FT / 4/3) mount, covering a 70–300mm focal length range. The maximum aperture measures f/4.0 at the wide end and f/5.6 at the telephoto end. Built with ED (Extra-low Dispersion) glass, the lens targets chromatic aberration control across its zoom range.
It is noted as relatively light compared to other Four Thirds lenses, which contributes to handheld usability — a minimum shutter speed of 1/125s is recommended when shooting handheld. The lens has no tripod collar, requiring camera-body tripod mounting. It is compatible with the EC-14 teleconverter, pushing effective reach to 425mm at an effective aperture of f/8.
For Micro Four Thirds shooters, the lens can be adapted using the MMF-3 adapter or the Viltrox AF adapter, with autofocus performing best on the OM-D E-M1 Mark I. Close focus performance is noted as an advantage over the 75-300mm alternative.
