Gain compared low, yet helpful

The AF-S 50mm f1.4 brings visible improvements here.
The Bokeh is much better when the iris is between 8.1 to 2.3. From aperture 4, the differences are only slight.
The selected images to illustrate it.

The overall focus should be at f5.6 to 8 also a bit higher, especially on full frame cameras according dpreview tests.
So far, this aspect only plays a subordinate role for me.

Anyone expecting a wow factor of this change, could be disappointed.

The gain is in a very narrow range and is usually. only details visible. On the other hand certain images and effects in the DX format are possible only with a lens like this.
The potential is more with some more visible CA bought (color fringing on high-contrast image transitions in the blurred area). Which in turn is not a product defect but a physical problem with fast lenses. This is for example shown good compared. at Photo Zone and dpreview.

The here sometimes criticized slow autofocus appeared in a direct comparison with the previous objective initially frightening.
He falls while photographing but only when you want to focus from close range to infinity. And that goes fast enough.
In the field of conventional distances to a selected theme, it does not bother me.

Amazingly well is the manual focus.
The ring has a pleasant resistance, has no play and a relatively large adjustment range.
The high light intensity reveals much even in low light.

Conclusion
Improvements in very large apertures can be recognized, but also more CA in certain situations.
Although the wow effect has failed to materialize, I will keep the lens. It does what I expected (see selected images).
Perhaps the AF-S 50mm f1.8 is for anyone who is concerned less about Bokeh, a good compromise.
