A large F1.8 maximum aperture makes it easy to achieve exquisitely expressive bokeh in deep, impressive images. 0.4 ft (0.12 m) minimum focus and 0.2x maximum magnification1 let you shoot close-ups with wide, smoothly defocused backgrounds. Precisely controlled spherical aberration and a 7-blade circular aperture contribute significantly to the beautiful bokeh this lens can deliver.

 

State-of-the-art optics deliver consistently high resolution right out to the image edges. Optimal placement of three aspherical elements ideally corrects field curvature, ensuring that excellent resolution is maintained throughout the image area, even at maximum aperture. Three ED (Extra-low Dispersion) glass elements effectively suppress chromatic aberration and color fringing for superb image quality.

The compact size and low weight of this fine lens make it a perfect match for APS-C cameras. Outstanding mobility and easy handling are great for long handheld or grip-mounted shooting sessions. An innovative combination of spherical and aspherical elements achieves stunning optical performance in a lens that is only 2-5/8 x 2-3/8 in. (66 x 57.5 mm) and weighs only 6.4 oz. (181 g).

 

 

Two linear motors give this large-aperture lens impressively fast, precise autofocus and tracking performance for both stills and movies. AF and tracking are so responsive that the full speed potential of the camera used can be fully realized so that even fast or erratically moving subjects can be captured quietly and reliably.

It may be small, but this impressive lens offers outstanding control and reliability. Linear Response MF provides instantaneous manual focusing with a natural feel, while a focus hold button and focus mode switch offer extra focusing control versatility. And to ensure maximum reliability in challenging outdoor conditions it features effective dust and moisture resistance³ throughout.
