Sigma 18-200mm f/3.5-6.3 DC OS für Canon

The range of this lens allows you to capture shots that might "escape" while switching lenses.
I have had this one for almost 2 years now. It served me very well. I took thousands of shots with it, many were was candids that I would have missed if I had to switch lenses.

The color and contrast are pretty good, and it is pretty sharp stopped down. You can make A3 prints straight out of the camera with no problems and if you do some post processing, even larger prints.

The optical stabilizer is fantastic and I was albe to take hand held shots at 200mm at 1/15 sec and even longer.
Indoors I use it with a flash so I am not concerend about the slow aperture.

The range forces compromises, the IQ is not as good as with primes or lenses with more conservative range and it is certainly not for purists.
The bokeh could be better but never to a point I bothered to fix it in post processing.
