A classic 56

In this price range, the performance is pretty good.

Obviously vignetting is very present in the end range (17mm) and obviously optics and a bit soft in the corners at full aperture.
In contrast sharpness becomes pretty good that the dice a little firm (f8)

I am however quite disappointed by the construction.
The frame is of metal but the rest of the lens is plastic.

After several months of use, the crown on which the fixed sunshade begun to take the game. This does nothing to impact the optical quality but shame.
Also, the zoom ring becomes rather hard over time.

However I do not intend to part with it so far. It's main objective as it is very versatile.
