Reduced chromatic aberration to help deliver high resolution imagesThe optical construction of 21 elements in 14 groups, which includes five ED lenses and a Super ED lens, delivers results comparable to a fluorite lens, and by reducing axial chromatic aberration it produces images packed with detail. The maximum magnification is 0.19x, enabling users to shoot telephoto macro images. | Class-leading 5.0-stop* image stabilizationA 5.0-stop image stabilization system — the most powerful in any super telephoto zoom lens — produces shake-free results even at the maximum telephoto setting of 609mm (35mm format equivalent). Also, if panning is detected, the lens automatically switches camera shake correction to the vertical plane only. Fast, quiet AF thanks to twin linear motors Twin linear motors are used to deliver fast focusing on moving subjects. The motors are also quiet, so the lens is ideal for shooting live music performances and theatre productions. Even faster AF shooting is possible with the focus limiter function, which limits the close focusing point to 5m. * CIPA guidelines based, at telephoto end. | Water / dust resistance, -10°C low-temperature operation and fluorine coatingThe lens features 13 water and dust resistant seals at 12 points, allowing you to shoot with confidence in tough outdoor environments. The fluorine coating applied to the front lens element is water repellent so it’s less susceptible to smudges and can easily be cleaned. |
