compact and lightweight design that makes the lens
wonderfully portable.

ambient lighting as well as beautiful defocusing at wide
aperture settings. This lens is highly effective in low-light
situations when used together with Super SteadyShot

image stabilization system, and is also recommended for
portraits. Captured images exhibit high resolution from

aperture is used to enhance the unique defocusing effect
of large-aperture lenses.

A compact macro lens with autofocusing from all ranges
between 1:1 magnification and infinity. Compared to a
macro lens with longer focal length, this lens provides a
wider frame for capturing more of the background in your
images. Magnificent image quality comes from its double-
floating lens construction, and a circular aperture ensures
beautiful defocusing. Close-ups can be taken from just
20 cm. To optimize handling, the focus ring does not rotate
during AF operation.

superior image quality, and 9-blade circular aperture
provides natural defocusing. Operability is enhanced by a
focus hold button, focus range limiter, and focus ring that
does not rotate during AF operation.
