The Olympus 75-300mm f/4.5/6.7 II lens provides a 35mm equivalent of 150-600mm in a compact and lightweight package. For micro 4/3rds users using cameras with built in image stabilisation this offers a more compact and lighter weight option compared to the Panasonic 100-300mm f/4.5-5.6 OIS lens.
Minimum focus distance is from 0.9-1.5m and the lens has the latest ZERO (Zeiko Extra-Low Reflection Optical) coatings reduce flare and ghosting.
For a lens of this power to be in such a small package taking only 58mm filters and weighing only 430g is truly amazing.
Olympus supply only front and rear caps - a lens hood is optional.
With an effective focal length at the long end of 600mm in 35mm terms image stabilisation is essential.
Used on the OM-D E-M5 or EM-1 the lens balances beautifully and handles extremely well.
Auto focus speeds are very good – especially where only a slight adjustment is needed, and despite the slow maximum aperture the image is bright through the viewfinder thanks to the electronic viewfinders of the OM-D range in particular.
Optical performance is excellent at 75mm to about 200mm even at maximum aperture, at 300mm performance dips to very good and is improved by stopping down slightly to f/8.
The only real drawback of this lens is the maximum aperture, if you are going to be using it in good light or are prepared to use higher ISO settings and the built in body stabilisation then it comes highly recommended. The closest competitor is the Panasonic 100-300 which offers a slightly faster maximum aperture throughout the range and built in stabilisation but in a larger package.
