Just occasionally a lens throws up a surprise. Not often, but when it does, we tend, by our very nature, to take a closer look. This budget zoom from Sigma is such a lens and we take a closer look.

Build and handling
This lens is nicely compact for it’s capabilities although it does extend somewhat as you zoom to the long end of the range. The extension, achieved by a double trombone, comes out some 52mm. It does so with quite a smooth action though and the second sleeve of the trombone carries markings to indicate the amount of magnification the optic is achieving. The zoom ring covers some two-thirds of the barrel with the manual focus ring occupying the remainder. It is similar in build and feel to it’s bigger brother, the 28-300mm. Autofocus, in this more budget placed lens, lacks the refinement of a sonic motor and although the motor can be heard, the noise is not obtrusive and the action is quite quick. This is probably achieved by the short amount of travel required, as when you switch to manual focus there is less than a quarter of a turn needed on the nicely torqued manual ring. The zoom ring is marked at 28, 35, 50,80, 135, and 200mm and neither zooming nor focussing rotates the front element, a bonus for filter users. At the business end there is a bayonet mount for the supplied petal shaped hood and this has a positive click to keep it in place.

Optical quality
This is where the lens started throwing up some surprises. Most lenses, especially those with a zoom ratio that exceeds 3:1, and this one is just over 7:1, deteriorate as the focal length increases. This one however, increased its performance towards the middle of the range, dropping back only as far as where it started at the long end. And it didn’t start badly either!

The lens does suffer slightly from barrel distortion at the wide end, measured at -2% with the Imatest distortion module, but this is one of the easier anomalies to correct in software. By the 200mm mark any distortion is negligible. Chromatic aberration is an area where many of this type of lens fall down but although it is present and measurable around the edges of the frame it manages to stay just inside tolerable limits. There is virtually none at the centre of the frame. The digital coating that has been applied universally to the Sigma range has had the effect of improving contrast and colour rendition and this is true of this optic.


Two shots of the same subject, taken from the same spot, the first at 70mm and the second at 200mm and both at f/7.1 on a 20D. Unusually, there is no noticeable drop off in quality at the longer shot unless measured in software.

The close focusing ability of this ‘macro’ lens is quite handy for large insect photography. My wife, Shirley, took this one on a 20D.

If you need a general purpose lens to carry on your camera, and use the long end as much as the wide, then this offering is well worth a look. The excellent resolution figures achieved through the middle to the long end are a pleasant surprise and make this optic one of those hidden bargains. The close focussing ability is a bonus too.

In summary, the positive points of the 28-200mm f/3.5-5.6 DG Macro are:
Good focal range
Compact and lightweight to carry
Excellent performance through the range
Cracking value for money

The negative points are:
CA around the edges at the wider end
Distrotion just evident

My current Sigma 28-135mm Macro lens's aperture now fails to close when shooting at the longer focal length settings. I started looking for a repairer but the cost was more than the lens so I am looking for a replacement. I used it for portraiture and macro shots, it was sharp for both but not harsh and my subjects loved it. However, getting a replacement is proving either expensive for a second hand example and impossible for a new one, until I saw the lens reviewed here.

I'm still looking to get a price on this lens, it looks like an updated version of the broken one I already have, and I'm hoping from the review it will produce a similar quality of images. However this is proving difficult to obtain too. Is this lens still manufactured?
