Sony FE 24mm f/1.4 G Master Review : Performance



Sony FE 24mm f/1.4 GM Performance

First sharpness and the lens is simply excellent centrally, all the way through from f/1.4 to f/16. At the edges, sharpness is very good at f/1.4, excellent from f/2 to f/11 and very good at f/16. It is difficult to see how we could expect anything better than this result, especially from such a fast ultra-wide.

The blue column represents readings from the centre of the picture frame at the various apertures and the green is from the edges.

The scale on the left side is an indication of actual image resolution as LW/PH and is described in detail above. The taller the column, the better the lens performance.

For this review, the lens was tested on a Sony Alpha A7R III using Imatest.

 

CA (Chromatic Aberration) is virtually banished at the centre. There is some CA at the edges, but this could easily be corrected in software and is not so extreme as to be a problem. On most subjects, it will not be an issue.

How to read our CA charts

Chromatic aberration (CA) is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software.

Apochromatic lenses have special lens elements (aspheric, extra-low dispersion etc) to minimize the problem, hence they usually cost more.

For this review, the lens was tested on a Sony Alpha A7R III using Imatest.

 

Distortion is virtually zero. We can measure +0.02% pincushion distortion, which of course is the wrong side of things for a wide angle; barrel distortion being what we would normally expect, but frankly, the result is so close to zero that even a macro lens could not expect to be any better. Effectively, the lens is rectilinear and straight lines will remain so, even at the edges of the frame.

Bokeh, the smooth, or in some lenses not so smooth, transition in out of focus areas of the image, is absolutely gorgeous. The rendition can be described as sublime.

Flare is absent, even in the most demanding shots no sign of it was seen at all. An exceptionally fine performance.

As expected, there is some vignetting, measuring -1.9 stops at f/1.4, -1.8 at f/2 and thereafter -1.6 stops down to f/8 and -1.5 stops to f/16. For many subjects this can be very effective as a pictorial tool, offering gentle corner darkening that concentrates our eyes on the main areas of interest. However, it is easily corrected in software if that is so desired.
