Macro
capability
This lens is capable of Macro photography, with minimum shooting distance
of 20cm (reproduction ratio 1 : 2.9) and angle of view is 75.4. You can
take picture not only the subject but also the surrounding scenery.
Large front element and Super wide-angle
The lens has an advanced optical construction, in order to obtain adequate
peripheral brightness with open aperture. Also, the iris diaphragm has
9 diaphragm blades to obtain beautiful out of focus images in the foreground
and background.
Handling
The lens incorporates a Dual-Focus (DF) mechanism. It is easy to hold
the lens, since the focusing ring does not rotate during auto-focus, yet
it provides adequate focusing torque of the focusing ring during manual
focusing of the lens. Also, this also allows the use of a Petal-type Hood
and the easy use of a polarizing filter.
Aspherical lens
It incorporates a floating focus system and uses two aspherical lens elements
for minimizing distortion, aberration and astigmatism.

Amateur
Photograher - September 2001 'This is a fast and quiet lens in operation, with the extra stop giving a bright, clear viewfinder image for picking out those details, particularly in low light...the vignetting aspect of the lens, even wide open, is astonishing. Dr. Bell measured vignetting on the bench, but in the field, to the naked eye, it is invisible. If you like prime lenses and appreciate the quality, the 28mm f/1.8 is a lens that is seriously worth considering. The near-human-eye viewpoint for the digital SLR user is another bonus that should ensure the optic's success.' |
