Digital Cameras Photo Reviews of Sigma 180mm f/3.5 EX IF HSM Macro Lens for Konica Minolta SLR CamerasCustomer Review: Sigma 180mm/3.5HSM (Nikon) Summary: 5 Stars
I shoot nature semi-professionally, and use a lot of pro Nikkor glass. This lens is among the highest in optical quality that I have worked with. The images remain sharp and contrasty at all apertures (remember that DOF is very shallow at 3.5 and 4), and the bokeh is very nice opened up. The color may have a slight warmness compared to Nikkor's 60mm/2.8. I have been banging this lens around in the field for a month or so; the build quality seems excellent, and the tripod mount is nicely balanced. Focusing is silent, fairly fast, and very accurate on F5, N90s, and N80. The manual focus (primary mode in macro photog.) is nicely dampened for an AF lens. I am shooting transparency film on a tripod with a cable and focusing stage. All in all this is a fine optic and it is priced reasonably.
Description of Sigma 180mm f/3.5 EX IF HSM Macro Lens for Konica Minolta SLR CamerasSigma's 180mm F3.5 EX IF HSM macro lens lets you take life-size, 1:1 images without the use of accessories. When shooting at this magnification, you can be a full 18.1 inches from your subject, ideal when your subject may be one easily disturbed, like birds, insects, and animals. In addition to the life-size images, this lens also uses the silent HSM (Hyper Sonic Motor) so you can truly capture those hard-to-get images without disturbing your surroundings or subject. The apochromatic design of the optics, combined with two SLD (Special Low Dispersion) glass elements plus a floating inner-focus system help control chromatic and spherical aberrations as well as astigmatism, optical problems that often affect the quality of your images. This effect gives you high-quality performance across the entire focusing range. This model is dedicated to Minolta AF SLR cameras.
