Conclusion: This is the perfect focal length for timid subjects like insects, allowing a practical working distance that minimises the risk of frightening them away. Despite its focal length and fast maximum aperture, the lens has quite a compact design. Its nicely balanced, well-constructed and the tripod collar makes it easy to switch from a horizontal to vertical format. Image quality is excellent, capturing very fine detail.
Lens Test: Sigma 150mm f/2.8 EX DG OS HSM APO Macro
10 March 2009
Excerpt: Photography’s only high-speed, 1:1, long-tele prime, Sigma’s optically stabilized 150mm f/2.8 ($1,100, street) replaces a similar, unstabilized lens from several years ago. More has been updated than just the OS mechanism: This lens produces significantly less distortion than its predecessor, and resistance to weather and dust has been vastly improved.This telephoto macro lens is no lightweight: At 2.54 pounds, it’s almost a pound heavier and a half-inch longer than the...
Conclusion: A well made and thought out macro lens with enough focal length to enable skittish insect photography without putting them to flight. Quiet and faster focusing with the ability to restrict the focusing to the area you are working in improves the experience also. Good balance on the excellent tripod collar makes for easy tripod work. Good, but not outstanding picture quality. A nice lens.
Pros: Quiet Focusing, quicker but not lightning., Lens does not extend, front element does not rotate., Excellent tripod collar., Ability to accept same make converters
Cons: Not quite as sharp as some., No belt loop on pouch
Sigma’s APO MACRO 150mm f/2.8 EX DG HSM; It’s A Macro Lens—Wait—It’s A Portrait Lens!
1 December 2001
Excerpt: While searching for a new portrait lens I saw Sigma's APO MACRO 150mm f/2.8 on their website. But wait, you say, this is a macro lens, not a portrait lens! Here's my thinking: Any portrait photographer out there worth his light meter will gladly extol the virtues of a long, fast lens for portraiture.
Excerpt: Practically every producer has a 100 mm class macro lens on their offer. What’s more, in the majority of cases, these are really well-done constructions so the competition on the market is fierce and the choice huge . When it comes to longer focal lengths, though, there is much less to choose from. For example neither Pentax nor Sony offer such lenses at all.
Cons: Average work against bright light,, Slow autofocus.
Summary: As you can see from the picture above, this lens is capable of superb results and even performs well enough at maximum aperture to double as a long portrait lens if shallow depth of field and compression of perspective is required.
Pros: Good resolution, Low levels of chromatic aberrations, Fast AF, Great build quality, Internal focus design, Price
Cons: Loss of contrast when shooting into the light
Conclusion: When we summed up the Sigma 2.8/105 Macro test performance we wrote that if that instrument had an HSM motor it would be close to perfect. Here we deal with another case – the tested Sigma 2.8/150 is equipped with an HSM motor but still it leaves a bit to be desired because of the inconsistent autofocus accuracy. However, it was the only flaw we managed to find.
Sigma AF 150mm f/2.8 EX DG HSM APO Macro OS (Canon EOS) - APS-C Review / Test Report
5 March 2009
Conclusion: The Sigma AF 150mm f/2.8 EX HSM DG APO macro OS is certainly among the very best macro lenses that we've tested here at photozone. It delivered great results in our full format test already and it is not worse in the APS-C format despite the comparatively higher pixel density of our base DSLR. The lens is capable of delivering very good results at max. aperture and the center quality does even reach excellent quality between f/4 and f/8.
Sigma AF 150mm f/2.8 EX DG HSM APO Macro (FX) - Review / Test Report
25 February 2009
Conclusion: The Sigma AF 150mm f/2.8 EX DG HSM APO performs on a very high level and delivers very good to excellent sharpness in the image center and very good border and corner sharpness at any aperture from wide open down to f/11, where diffraction begins to reduce resolution. Combined with the Sigma 1.4x APO DG tele converter the resolution is a bit lower, but still on a high level, at least when stopped down a little.
