About Sigma

Taking picture of small animals & 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 & 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.

The 180mm F3.5 APO MACRO lens has a very narrowfield of view, & 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.

The Floating Inner Focus System of the APO MACRO 180mm F3.5 EX HSM provides highquality optical performance and superior handling & stability. This system moves two lens groups within the lens, so the lens' physical length remains unchanged. This technique also maintains good correction for Spherical Aberration and Astigmatism, and provides extremely high optical performance frominfinity to 1:1 Macro.

Macro photography requires precise focus adjustment. The HSM (Hyper Sonic Motor) feature is ideal for this purpose as it allows quick and precise manual focus, even in auto focus mode. Simply focus with HSM auto focus, then while partially depressing the shutter release, turn the manual focus ring until any desired focus adjustment is made. Then depress the shutter release. It is not necessary to switch from AF to MF. When the shutter release is next depressed, the AF function will resume. Of course the AF function can bedisabled altogether, and only MF used, if desired.

Macro photography can be further enhanced by the 1.4x APO EX tele-converter, which allows the photographer to use the new SIGMA APO 180mm F3.5 MACRO lens as a 252mm F5 lens while maintaining auto focus function from infinity to 1.2m(47.2in.) with Canon, Nikon and Sigma cameras. At distances closer than 1.2m (47.2 in.) the lens automatically switches to MF mode. When this lens and the 1.4x EX tele-converter are used with Minolta or Pentax cameras the lens must be focused manually. When used with the 2x EX tele-converter, the 180mm F3.5 lens becomes a360mm F7 lens with manual focus function only, regardless of camera mount.

Image quality depends in part on color Aberration, which occurs due to differences in the wavelength (color) of light, causing the different colors to focus at different planes. SLD glass in the front optical group helps compensate for this phenomenon, and enables the lens to deliver images of high optical quality, having outstanding crispness and sharpness.

Worth every penny

Awesome product, best macro lens for the buck period. Using on Canon 40D and planning on using it with my Canon 7D for macro HD video. Fast and sharp, need time a bit to adjust myself to the lens, it took a few clicks and now I am rocking!!!!!!!!! Thanks to Sigma and thanks you guys from Adorama.[...]

Adorama Quality !

By

This review covers the item purchased as well as all the other items I have purchased from Adorama. This particular item was used, and in mint condition...they are true to their ratings, if not better on used equipment. As for the new things (Mark III camera and a Canon 300L lens), they are equally reliable, honest and prompt. Other things have arrive in 2 days, and the used equipment that I sent them is posted to my account immediately. I cannot say enough good about Adorama !

This is a great Macro lens!

By

I love this lens! It is very responsive and takes remarkably clear images....The Macro function of this lens is really great! Both in auto focus and manual focus. The quality of this lens is comparable to Canon. I would recommend this lens to anyone who would like to take some serious macro shots!

Super sharp, super sweet

By

This lens has effectively replaced my Canon 100/2.8 macro in all cases except backpacking. The image quality is superb! It has more working distance and that helps not disturb bugs, etc. It matches or exceeds the Canon 180 except being much cheaper. If you love macro, this is the lens for you.
