- Pronounced distortion across much of the range
- Extremely soft at 135mm
- Rather average close-up performance
- Zoom creep
Just occasionally, the old cliches are still the best, and with the 18-200mm VR the phrase 'jack of all trades, master of none' springs immediately to mind. It's a lens which delivers somewhat flawed results over its entire zoom range; where it's sharp, it has heavy distortion, and when that distortion comes under control at the long end, it loses sharpness. Its close-up performance is reasonable, but not spectacular, and overall it will likely be outperformed optically by a cheaper combination of standard and telephoto zooms.....
So when all is said and done, we have to understand that superzooms are essentially about making some optical compromises to provide the broadest possible range in a single lens, and it's up to each individual to decide whether those compromises are acceptable. I wouldn't recommend the 18-200mm to someone whose primary interests were either architecture or wildlife, for example, but for the photographer who wants to shoot a little bit of everything and not have to change lenses, it's more than fit for purpose.........
