A very well-made lens. The price is good, shipping and packaging was also good. In practice, it is certainly as the sole objective use-particularly for photos with the Kameraautomatik-. When heavy lenses a slight blur at the edges can be seen. Can easily correct with the appropriate editing software. Otherwise, I noticed nothing negative. Making a purchase as the only universal lens I can only recommend. Particularly impressed me was the extremely good workmanship and compact design.
