Sigma is saying.

The Sigma 105mm F2.8 Macro EX DG OS HSM  lens has become one of my favorite lenses for macro photography in the field. So what makes me reach for this lens when Sigma offers five macro lenses when I own all of them? The answer is balance- the 105mm lens is really good at everything and one of the best in terms image quality. This lens can give you the sharpest results possible with an excellent balance of size, weight, working distance at a very high value per dollar price.

The strongest feature of the 105mm F2.8 Macro is image quality. It offers sharpness and resolution that is amazing, take a look at the 100% crop sections of the full size images in this post to get an idea of just how sharp this lens really is. All the images below were made handheld or with a monopod and a single diffused wireless flash.

When it comes to choosing a macro lens, balance is important since there is never a perfect solution, everything is a selection of trade-offs. The Sigma 105mm for example might not have the same super creamy bokeh of the Sigma 180mm macro, but in the field the 180 macro can be a challenge to work with flash because of the long working distance. The trick is that when you need the softest background possible you can always shoot at a wider aperture and stack frames to get the depth of field you need.

Its important to look at everything a macro lens has to offer and avoid getting fixated on only one or two criteria. The Sigma 105mm F2.8 EX DG OS HSM Macro lens is one of my favorites for field work and is an excellent all around macro lens.
