High ratio zoom lens housed in a compact construction and incorporating Sigma’s original OS (Optical Stabilizer) function.
The Sigma Corporation is pleased to announce the launch of the new APO 150-500mm F5-6.3 DG OS
HSM.


Incorporating Sigma’s original OS (Optical Stabilizer) function.
An ultra-telephoto zoom lens covers a telephoto range up to 500mm and allows short perspective.
Three SLD glass elements and a rear focus system provide optimum image quality throughout the entire zoom range.
Super multi-layer coating reduces flare and ghosting.
HSM ensures quiet and high speed autofocus.
Compatible with Sigma’s APO Tele Converters.
This ultra-telephoto zoom lens covers a telephoto range up to 500mm and allows photographers to bring the subject close and short perspective. Sigma’s original OS (Optical Stabilizer) function offers the equivalent of using a shutter speed approximately 4 stops faster. It is ideal for sports, wildlife and landscape photography with handheld shooting.

Three SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic aberration. This lens is equipped with a rear focus system that minimizes fluctuation of aberration caused by focusing. The super multi-layer lens coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focusing capability.

The addition of the (optional) 1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 210-700mm F7-9 MF ultra-telephoto zoom lens or a 300-1000mm F10-13 MF ultra-telephoto zoom lens respectively. A removable tripod socket (TS-31) is included as a standard component.
*1 OS function is not available.
*2 If the camera body does not support HSM motor, AF does not work.

Another one Review
June 2008

The first impression is that this is a very well built lens. It feels solid and somewhat heavy. However, once mounted on my Canon 350D (with battery grip attached) it feels well balanced and easy to operate.

I did find though, that after a few minutes of trying to track a sunbird the lens felt very heavy and it put some strain on my wrists. I guess most photographers would want to use this lens with a tripod or a monopod.

Sigma have done very well to include a lens hood, tripod collar, shoulder strap and a padded carry bag.

The optical stabilisation works well and I was able to capture some images handheld at shutter speeds as low as 1/200th sec. Generally speaking I found 1/800th sec or faster produced better quality images. Bokeh was very smooth and pleasing.

The image quality is slightly better than that of the Canon 70-300 IS lens in my opinion. But the longer reach of this Sigma makes it much more suitable for bird and wildlife photography. I can’t compare it to the Canon “L” series lenses, but never-the-less I was satisfied with the results I achieved and I am sure that the quality is more than good enough for my aim to sell photographs.

Autofocus worked very well. I was surprised at how quickly it focussed. The true test though would be focussing on birds in flight.

The biggest drawback with this lens is that it is not a low light lens - f6.3 at 500mm requires a fair amount of light, so as the sun begins to go down the lens does not perform well.

Sample shots
Below is a selection of images from a two hour visit (late afternoon) on 6 June 2008 to the Addo Elephant National Park near Port Elizabeth, South Africa.

All photos were hand held or rested on the window of the car.
AE mode was used so all photos are at f6.3

Sigma 150-500 APO DG OS controlled test
June 2008


Our mini field test of the Sigma 150-500 APO DG OS proved to be quite popular, so we decided to perform a further, more "scientific", test under controlled conditions.

Lighting was provided by Elinchrom D-Lite 4 Studio lights and metered with a Sekonic L-308 Flashmate.

A Canon 350D was used for each photo with all seven autofocus points activated.

From the test it can clearly be seen that the best results are obtained if the lens is stopped down. Using f6.3 at 500mm produces soft images, but quite useable in most circumstances. At f11 and above excellent sharpness is obtained.

Our conclusion is that when the available light is low it would be preferable to up the ISO speed to ISO400 or even ISO800 in order to avoid using f6.3 and f7.1. This may result in some extra noise, which could be cleaned up during post processing using Noise Ninja or a similar noise reduction utility.

At the price this is an excellent lens and in bright light produces top quality results. The biggest drawback is the maximum aperture size means that this lens is not suitable in low light conditions.

Sample shots
All the images below were taken at 500mm focal length.
No post processing has been done to the 100% crops.
The full images have been downsized and a little unsharp mask applied.
