I have recently obtained a new 50mm Nikkor, f/1.4 lens, previously I was mainly using a 24 to 120mm zoom at this focal length and on many occasions I was not all that happy with the image quality of the zoom.

Zoom lenses are always a compromise in many respects. Zooms are very convenient and are generally quite good at one focal length but not not so good across the full focal length range, also they generally do not offer low apertures for selective focus.

With the 50mm f/1.4G I am finding that the lens is excellent if you want to isolate the subject using selective focus. The depth of field becomes very narrow between  f/1.4 and f/2 and this is impossiblw to achieve with any zoom lens.

This lens is ever so slightly soft at f/1.4, it is very difficult to see if it is because of the very narrow depth of field or because of the lens softness.  At smaller apertures of  f/2.0 or smaller it is very sharp.

When you consider the price of this lens it appears to be a bargain if you are aiming for very selective focus.
