Looking for suitable additions to the kit lens of my EOS I came quickly to this little marvel: In most reviews the tenor was "Who does not buys is your own fault." And my judgment confirms this: The lens is very sensitive to light compared to many other hobbyists / entry-level lenses and for approx. 100 euros a real bargain. Ideal for portraits! Of course it can not compete with L-lenses or other high-quality lenses of the professional class, which it wants not but. The build quality is low, the results fantastic.
