Much better than Tamron

It pleasant surprise by taking charge this new objective. Indeed, I had a Tamron 18-200 and barely a year later, an error message Communication with the objective appears on my camera. I inquired and it turns out that in my surroundings that also happened to someone. So I decided to take this model, slightly more expensive but much better finish. In video mode finished judder when zooming. Moreover stabilizer and Hyper motor speed are effective. No vignetting found to be 18 to 200.
