After intensive reading the many conflicting reviews, I decided to make my own experiences and (incidentally a wonderful DSLR - even for beginners), the Tamron 18-270 shortly before my vacation as a travel lens for my Sony Alpha 65 bought. I did not want to be on the road with several lenses in the summer. Conclusion: From the beginning I was happy about my decision. A wonderful journey lens with good performance. I can not fault anything neither on autofocus still on the picture quality. It is true that the Tamron extends solely in the unlocked state. But I can live with, because there is the mounting-foot-on Tamron this. I have not regretted the purchase, but enjoyed the slight flexibility on vacation. The Tamron makes me haptically a high impression. However, I am neither pro nor semi-professional, but advanced amateur with enthusiasm at the Fort winding my photographic skills. Can recommend it to anyone minded without excessive professional requirements fully the Tamron.
