We've just acquired a gem that is the Sigma 180mm f/2.8 OS Macro lens for Canon:
- 180 mm f/2.8 Macro Lens
- Canon EF Mount
- 1:1 Magnification
- Optical Stabilizer Function
- FLD Glass Elements Reduce Aberration
- Floating Inner Focusing System
- Multi-Coating Reduces Ghosting and Flare
- Hyper Sonic Motor for Quiet Focusing
- Minimum Focus Distance of 18.5" / 47cm
Any form of stabilization is appreciated, and sigma's optical stabilization is well implemented here. Although 180mm is not terribly long, turning OS on provides for a smooth telephoto experience even when your arms start to grow tired after hand-holding for a longer session. Regarding autofocus, we had no issues with accuracy, and although not a speed-demon, the focus-limiter allows you to skip the macro range, leading to an acceptably fast autofocus experience.
While we were out for brunch, we decided to test out our new lens with some environmental portraiture. When the situation permits, we prefer to shoot portraits with longer focal lengths to provide a bit of compression to flatter our subjects. The Canon 135mm f/2.0L lens is one of our favorites for this task, particularly because of its small form factor and relatively light weight. The Sigma 180mm f/2.8 OS provides more compression owing to its longer focal length, but you would be hard pressed to notice any difference unless comparing side by side. Regardless, subject positioning and the interplay of light and shadow will still play a major role in how we perceive facial features in the end product. Comparing the images above, the one on the left was shot with the 135/2.0L, and the right with the 180/2.8: despite affording you more compression, the face on the right appears flatter, and less slender than the left, due to the direct positioning of the face with little to no shadow to provide contouring and shape.
We won't bother delving into tests charts for image quality and sharpness comparisons, as that is not what we shoot, and there are plenty of great sites out there to please the pixel peeper. How does it measure up to its competitor - the Canon 180mm f/3.5L? In favor of the Sigma is a faster aperture, optical stabilization, lower price, more included accessories, and (in our opinion) better looks. In favor of the Canon: lower weight, and the assurance that it will work with all current and future Canon DSLRs.
Once we have a chance to take some actual macro shots using this lens we will post a review on that as well. Until then, overall this lens handles itself spectacularly for taking portraits and candid environmental shots. The only drawback we could think of was that it may be too cumbersome for some due to the sheer size and weight of this lens. Weighing in at a hefty 3.6 lbs, it is absolutely hand-holdable...for a time, but after an hour of shooting, you start to wish you had brought at least a monopod.
