Latest Review Posted | Sigma DC 18-200mm F3.5-6.3 I purchased this lens nearly two years ago since I wanted an all-purpose lens for use when not doing serious photography, e.g. when walking or sightseeing. I also chose it because it gives me a reasonable close focus facility hand-held using the image stabilisation on my K10D. I would have considered the Pentax version but it wasn’t available when I purchased the Sigma; other slightly longer zooms have since appeared.
This is an excellent lens for the amateur providing good well saturated colour and sharpness for landscapes, portraits, occasional long shots for wildlife, and macro (1:4.4 nominal but 1:3 approximately with APS). It is well-balanced and easy to use and not too heavy to carry around all day. One has to accept that in dull light its speed is a limitation. The zoom ring lock is a distinct advantage to prevent the zoom extending when being carried. I purchased it to replace the basic Sigma 18-50 and 55-200 kit lenses and have not been disappointed. It will never replace lenses such as prime wide angles, long telephotos or macros but it does the job it is intended to do quite well and if one requres a long zoom range 11:1, there are only a few of alternatives and none what one would call "professional" quality. |
