After I had familiarized myself with the technical features of the camera and lens, came to me in my photo trips very soon doubts about whether a fixed-focal length was a good investment.
So I bought a Tamron 17-50mm it. This gave me more freedom now, but pointed at the same time, what a outstanding features, the 50mm f / 1.4.
This is now again my "Always top". The wide aperture and outstanding central and edge sharpness are unparalleled. Even without IS can shoot with ISO800 and f / 1.4 from the hand still sharp photos at moderate lighting conditions. Especially for portraits the lens is ideal, and creates great bokeh effects in the background. That just looks alive and professionally.
It is to use quite at full aperture, provided you get his goal in the narrow focus. From f / 2.0 it is really sharp. From f / 3.5 to f / 5.6, the focus seems to be on the highest (interesting for architecture, star, etc.) and also takes off slowly.
In high contrast scenes, for example, with a backlit, clearly showing chromatic aberrations. Mostly, these are but manageable.
The focus ring is harder than any other lenses that I had in my hand. However, this falls to only manual fine adjustment. The AF is quick and accurate.
I would recommend the lens absolutely, for the DSLR newbie who has perhaps already collected with a Zoom experience. The price appears when you look at the all-optical properties, a bargain.
