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
Summary: Sigma APO Macro 150mm f/2.8 EX DG HSM is a very solid performer - the lens shows excellent image quality combined with practically non-existent distortion and low levels of color fringing, excellent build quality and very reasonable street price. There are a few issues that users should be aware of - vignetting on full frame cameras is somewhat heavier then what one would expect from a medium telephoto prime and flare handling is simply awful.
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...
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.
Sigma AF 150mm f/2.8 APO EX HSM macro DG D - Review / Test Report
11 May 2007
Conclusion: The Sigma AF 150mm f/2.8 EX DG HSM APO macro is one of the few third-party lenses that can play in the league up there with the big boyz. The performance figures are excellent and leave really nothing to be desired across all tested quality characteristics. The mechanical build quality is very good thanks to a metal body and a true IF (internal focusing) design with a constant physical length.
