On the side I: Handy, lightweight, effective image stabilization, good imaging performance, faster and quieter drive. In addition, the lens can withstand hervoragend with my Ranox Nahlinse and thus becomes a favorable macro replacement. Especially the way I appreciate the light weight and compact size. Previously I had a Sigma 70-300mm, but that I had mostly not there, because it was too heavy and bulky to me. Moreover, I find an image stabilizer with a telephoto simply important.
Restrictions: Not particularly bright, the processing could be a little high (Plastikbajonet only).
Still, for the price very reasonable value, so 5 stars.
