The lens works of high quality and well made. The somewhat rough rubbery surface is good and slippery in his hand. Compared with the model without image stabilization, it is however also larger and heavier, but still handy.
The image stabilizer is switched on. Once you tap the shutter, you can already see in the viewfinder as he works. And since then I wonder how I previously got along without this technique. Even at full focal length and 1/10 second exposure time still sharp pictures to be photographed in a private sale. That the stabilizer brings so much, I did not expect.
The autofocus works quickly and with a pleasant hum, unfortunately without Ultrasonic Motor, but you can not have everything. The imaging performance for the price range is perfectly fine. If you registered on the website of Sigma, one three-year warranty will also receive.
Thus, the Sigma 18-200 DC OS is an excellent all-round lens that fully plays out its strengths especially with long focal lengths and low light conditions, but also proposes to significantly heavier impact.
