| Latest Review Posted | Sigma 18-200mm F3.5-6.3 DC Macro OS HSM (Contemporary)
Sometimes you just need to take snapshots. Sure, you could use a mobile phone, but even in 2021, phone cameras can't zoom in very much and if you start cropping, the results are not satisfying. That's where a super-zoom lens comes in handy, and the Sigma 18-200mm Macro OS HSM (Contemporary) fulfills that role well. Image quality is good for a lens with 11x zoom, generally on par with the Pentax 18-135 for most of the focal lengths these lenses have in common, with the Sigma performing somewhat better above 105 mm. It is compact and sturdy; auto-focus is quick and quiet. There are some significant caveats: chromatic aberrations are fairly noticeable at the wide end, distortion is present (particularly at the wide end), and the lens is not weather-resistant. It's not perfect, and I have other lenses that perform better at each focal length covered by this lens, but when you don't know what you might need, this a good lens to have sitting on the camera, ready to go.
Previous reviewers have commented negatively on the bokeh, but I don't find it problematic.
