Sigma’s APO MACRO 150mm f/2.8 EX DG HSM; It’s A Macro Lens—Wait—It’s A Portrait Lens! Page 2
I'm a portrait guy but I used to do quite a bit of studio commercial shooting, so I borrowed a piece of jewelry from a local store and did a little setup. After creating the set and positioning the lights I was ready to get right in there and shoot. Here's where I found out how useful that rotating tripod collar is. I don't use tripods much and when I do it's usually level. Seems like my trusty pistol grip wasn't going to hold this weight at the angle I wanted no matter how much I tried to increase the tensioning. At first I tried to set the legs unevenly and then it hit me--just rotate the lens and the body will go with it! Worked like a charm, and it's brilliant for close-up work.
This is one beautiful lens. I know what you're thinking, why don't I just get an 80-200mm f/2.8 lens instead of this one fixed focal length. Good point. The big factor is the weight of such a zoom (almost 50 oz) and, to some extent, cost. Plus, zooms with close-up capability won't get you to life-size without some jury-rigging. All in all, the benefits are a great, really long portrait lens along with wonderful macro capabilities.
I usually manually focus my other macro lens since it gets "fooled" often and "hunts" for focus. This lens does not. I used it on autofocus and it snapped everything right in. Images also seemed to have more snap, color saturation, and overall sharpness than with my older lens.
If you're looking for a macro lens with plenty of working distance or a long and silent portrait lens, this fills the bill. Come to think of it, it makes a great sports lens for Nikon cameras, especially with the smaller "cropped" format you can use with the Nikon D2X and new D2Xs.
