Having the Sigma AF 180mm f/3.5 EX HSM APO is really advantageous if you like to shoot small animals and insects which can be really difficult as they often run or fly away.
The Sigma AF 180mm f/3.5 EX HSM APO employs an IF (Internal Focusing) system that maintains the overall length of the lens during focusing. Uses two LD (Low Dispersion) glass elements that effectively compensate for chromatic aberration. Provides high-contrast, outstanding image quality and a soft out-of-focus background effect. Incorporates an AF/MF one touch switchover mechanism built into the focus ring(for Canon & Nikon only). Super performance series provides high performance through outstanding design specifications. Features the new FEC (Filter Effect Control) function that enhances operational ease of Polarizing Filter use.

Photozone has recently posted a review on Sigma AF 180mm f/3.5 EX HSM APO macro and writes;
“The Sigma AF 180mm f/3.5 EX HSM APO macro is a very capable macro lens with very high resolution figures, marginal vignetting and non-existing distortions. Unfortunately CAs are a on the high side which is unusual for a tele fix-focal lens – this is a correctable issue though (via PS ACR, RawShooter, etc.). The build quality is very high and thanks to HSM the AF operates pretty fast and virtually silent. Compared to similar genuine brand lenses the AF 180mm f/3.5 EX APO macro is an absolute bargain at less than half the costs. However, all-in-all the Sigma AF 150mm f/2.8 EX HSM APO macro DG was a little more convincing.”
Shutterbug did a review on Sigma AF 180mm f/3.5 EX HSM APO macro and wrote;
” As mentioned at the outset, the image quality produced by the Sigma APO Macro 180mm f/3.5 EX IF lens was impressive. Images made with extreme close focusing appear razor sharp under an 8x loupe, with the most intricate detail crisply defined. Contrast is snappy and there’s no evidence of color fringing even at f/3.5. I found no need to stop down to f/16 for high sharpness across the entire frame as with some macro lenses. In fact, image quality is excellent at all f/stops from f/4 to f/8. At f/11 and f/16 overall sharpness remains very high. By f/22, center sharpness is still high, but corner sharpness does suffer, as with many lenses, due to diffraction, the bending of light rays as they enter a very small aperture. However, the greater depth of field produces an impression of higher sharpness, because all parts of a blossom are within the range of sharp focus. Hence, it’s not necessary to avoid these apertures.”
