Super lens - but a little hard

Had been the EOS 550D with kit lens (18-55) and Canon Zoom Lens EF-S 55-200.
Actually, as a beginner a good combination but bugged me change the permanent lens, especially in dusty environments. Furthermore then kept coming back to that again was for spontaneous recording the wrong lens on it when traveling.
Now I cover with the Tamron with good Lichtstaerke more than the two lenses from,
This is great fun and allows considerably more beautiful shots.
Something hard I do me still with the high weight and the camera in hand at 300mm to keep quiet, but I hope this is matter of habit.
For completeness: I bought me also the EOS700D, have now so the Tamron on the 700!
