Although I can call my own the very reasonably intensive SAL1650F28, I can not get around the 35-ies and 50-ies fixed focal length. Both lenses are really the hammer and an asset to any Sony.
Although the lenses are characterized by a lot of plastic, they make a quality impression and burden especially not so in weight.
I can only tell the SAL50F18 as already that I've never had so little committee. Again, that the partial blur at F1.8 does not bother me at the edge and I honestly have not seen it. Ultimately, I'll never take pictures with F1.8 and expect sharpness across the entire image. Much more I do that in order to achieve blur in this aperture range. And the film is suitable for the lens.
Top, 5 star, strong buy recommendation
