Sigma 180mm f/3.5 EX DG IF HSM APO Macro Lens Taking
picture of small animals and insects can be difficult, because they
often run or fly away, or can be dangerous or become aggressive if
you approach them. Therefore it is advantageous to have a greater working
distance between the camera and such subjects. Longer focal length
lens can provide this greater distance, but most long lens do not focus
close enough to provide a large image of small subjects. The
tele-macro type lens solves this problem by producing a large, high quality
image, up to life-size, while maintaining a long working distance. This
can enable you to capture on film the world of photomicrography, without
disturbing the subjects. The 180mm F3.5 APO MACRO lens has a very
narrow field of view, and can allow very narrow depth-of-field for selective
focus and less distracting backgrounds.
This lens is most desirable
for photographers who are serious about producing high quality images
both of macro subjects at life-size reproduction, as well as normal
telephotography.
