Sample Images

Here're some sample images taken with the Alpha 700 and RAW-converted via CaptureOne 4.1. Sorry for the rather mediocre quality but the weather was dismal at the time of the review.

Verdict

The Sony 50mm f/1.4 is a typical representative of the standard lenses that were designed back in the 70s to 80s. The max. aperture (f/1.4) should be generally avoided due to weak contrast, poor borders and a significant amount of longitudinal chromatic aberrations (LoCA). The image quality is already vastly improved at f/2 including a technically better (smoother) bokeh. The truly excellent peak performance is reached around f/4. As to be expected neither distortions nor vignetting are real issues but lateral CAs could be lower for a fix-focal length lens.
The build quality is pretty decent and the conventional screw-driven AF is very fast although somewhat dated regarding Sony's SSM (supersonic motor) ambitions. At around 320€/US$ the lens is priced at the upper end compared to the other major brands - maybe some food for thought over at Sony.
