DG Lens for Digital
A standard focal-length macro lens
ideal for shooting small items such
as accessories that require precise
positioning. Its floating focus system
delivers high image quality from life-
size shots to distant objects. Aberrations
are corrected from corner-to-corner of
the image. The lens excels in capturing
texture, making it ideal for macro
photography. It is also an outstanding
choice for general and portrait use. The
supplied screw-type round lens hood
can be fitted with a circular polarizing
filter. An aperture of F45* is provided to
enable extraordinary depth of field.
•Lens Construction; 9 Groups, 10 Elements
•Minimum Focusing Distance; 18.8 cm (7.4 in.)
•Magnification; 1:1 •Filter Size; ø 55 mm
Lens hood (LH550-02) supplied. Lens case, lens hood (LH620-01) supplied.
A large aperture medium-telephoto
macro lens suitable not only for shooting
flowers, insects, and other tiny objects,
but also for landscapes and portraits.
When mounted on a DSLR having an
APS-C size sensor, the angle of view
approximates that of a 105 mm lens
on a 35 mm SLR. SLD glass with a high
refractive index and the latest optical
design assure sharp images, while the
Super Multi-Layer Coating minimizes
flare and ghosting. A floating focus
configuration avoids fluctuation of
aberration due to focusing, thereby
maintaining high resolution and pristine
image quality at all focusing distances.

•Minimum Focusing Distance; 25.7 cm (10.1 in.)
•Magnification; 1:1 •Filter Size; ø 62 mm
