Sigma 180mm f/3.5 EX DG IF HSM APO Macro Lens for Nikon SLR Cameras

Sigma 180mm f/3.5 EX DG IF HSM APO Macro Lens for Nikon SLR Cameras

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.

Customer Reviews

Nikon Sigma 180 Macro, inconsistent auto focus
I purchased this lens because I wanted more distance when taking macro photos. As I do with all new lenses I purchase, I calibrate the AF (I have a Nikon D300 with AF Fine Tuning capability). What I found is that the AF on this lens has too much back lash to consistently focus. I took 5 pictures of a static object using a cable release and the camera mounted on a tripod. Before each picture was taken, I would rotate the focus ring either clockwise or counter clockwise. The results were 2 pictures focused behind the object, 2 focused in front and only one focused on the object. The object I was focusing on was high contrast and the lighting was midday sun so that the cameras AF had adequate parameters to operate properly. Maybe I got a bad example of this lens, but the poor AF repeatability was not acceptable. I returned the lens. I was very impressed with how sharp the lens took pictures, but not impressed with the amount of hysterisis in the AF mechanism. As for the returning of the lens to Amazon.com, the process is very simple and easy. I am impressed with their customer service. Too bad that Nikon doesn't have a more affordable long reach macro lens, also Nikon could learn a few things about tripod collar mounts from Sigma. The tripod collar was beautifully engineered.

Razor sharp lens!
After using Sigma 105mm f2.8 macro, I have bought 180mm for more working distance between me and the object. This is a top quality lens with inner focus, Hypersonic motor and sigma EX finish. I recommend everyone who want a real macro lens!
