The lens has a large maximum aperture of 1.4 which conjures up a very nice bokeh and a can play wonderfully with the depth of field. The large maximum aperture you can take pictures even in dark rooms with little ISO.
The image performance of this lens is really unique. The colors, contrasts and sharpness leaves no wish unfulfilled. I really love to take pictures with the lens and have thus achieved my best results so far. The 1,4er lens is definitely no comparison to 1,8er. There are image-technically really worlds apart. Everyone likes to be 1,8er 50mm lens that 1,4er will love. A switch, which you will not regret.
Conclusion: The lens is perfect in every aspect. Processing and value is great and the pictures are to excel in contrast, color reproduction and sharpness hardly. In addition, the fixed focal length always also offers a creative multi-profit, so for those who want to evolve photographically also a good investment.
