Positive points of the product:
Delivery as always quickly and without problems (1 working day).
Bright and well suited for shooting without a flash even in low light conditions.
Amazing close-ups are also possible because less focus distance (about 20 cm from the sensor plane).
Very good, experimental Focus possibilities with good bokeh, at maximum aperture in the millimeter range.
Autofukus quickly and quietly and mostly fail!
Although processing of plastic clean and robust (except the sun visor).
Inner focus, patch sun visor does not rotate at foci (the keuert in Kitobjektiven).
Rattenscharf from Aperture 4!
Negative points of the product:
Sunshade mE too large and schlabberiges plastic.
At maximum aperture F1.8 on the screen light blurs and CA (color bleeding). From Aperture 2.4 then everything ok.
Manual focus adjustment tricky because not fine consistently enough.
Those are my first impressions after about 50 shots today on the delivery of the objective. Compared to my old 50mm F1.4 M42 thread with Sony adapter lens, this new lens is much better even in the automatic position of the camera in difficult lighting conditions. For manual adjustment of the contrast advantage is again violently over the old piece of glass!
Conclusion: Highly recommended and there would have been nearly 5 points when there does not interfere with the bit CA at maximum aperture. But for this price of the lens so that I can really live well!
