Sigma 150mm f2.8 APO Macro DG EX HSM

Review Date: Dec 25, 2006 Recommend? yes | Price paid: Not Indicated | Rating: 9 

Pros: Superb image quality, even at f/2.8. Nice bokeh. Silent HSM.
Heaviest macro lens I ever used. Somewhat difficult to handhold on an EOS 30D. I would have been happier if this lens had an IS, even if it made it heavier!

This is my third Sigma macro lens in the past 10 years and I am very happy with it. It is heavy, but it feels solid. Images are sharp even at F2.8. I use this lens on a Canon EOS 30D. This lens produces exceptional results.

Autofocus is reliable and silent, but a bit slow. I guess this is normal for such a macro lens. You wouldn't use autofocus for close-up work any way. Its focal length and wide aperture make this lens suitable for portraits as well.

A 3 position focus limiter switch minimizes focus hunting. The supplied lens hood needs to be mounted at all times.

I like the fact that it has an internal focusing system. The front element doesn't extend or rotate when focusing.

Although I am very happy with the optical quality of this lens, it is somewhat difficult to handhold. On a 1.6x camera such as the EOS 30D, the effective focal length becomes 240mm. This means you need to have very steady hands, or shoot in bright light, or increase camera ISO, or use a tripod.

One of the benefits of a lens based IS system (besides obtaining sharp images) is to stabilize the view finder image, thereby reducing eye strain. If this lens had an IS system, I don't think I would have taken it off of my camera. Nonetheless, I have learned to have very steady hands when using this lens. The end results are worth it.

I gave an overall rating of 9/10 due to the absence of the IS.

Here are a few sample images:
