Samyang XP 50mm f/1.2 Review

Samyang XP 50mm f/1.2 Performance

With a lens designed with 50MP camera bodies in mind, we would expect a high level of performance. Central sharpness delivers this in style, starting off being very good at f/1.2. Sharpness then becomes excellent from f/2 through the f/11, before falling back slightly to very good at f/16.

The edges exactly follow the pattern of the centre, being very good at f/1.2, excellent from f/2 to f/11 and very good at f/16. This is a very impressive and even performance.

How to read our MTF charts

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 Canon EOS 5DS R using Imatest.


CA (Chromatic Aberration) is is also impressive, with central measurements being around two tenths of a pixel. The edges are slightly less well controlled, but still deliver impressively low figures. If required, this could be further reduced using software.

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 Canon EOS 5DS R using Imatest.

 

A fast 50mm lens would be expected to show some barrel distortion and the Samyang measures -1.57%. This is a good performance and there were no real signs of CA in the sample pictures. There are also software solutions.

Flare does not seem to be a problem, backlight causing no reduction in contrast.

Bokeh, the smoothness and gradation of the out of focus areas in an image, is an important consideration and the Samyang offers a very pleasant and smooth look.

Overall, a very high standard of performance and a lens that can deliver the goods with the largest pixel count sensors.
