Being heavily based on Zeiss Sonnar 50/1.5, Nikkor 50/1.4 was a fine performer for the era. It did indeed easily outperformed Summarit, but it would be a stretch to say that Nikkor was better than Summilux. Nikkor and Sonnar suffers from severe vignetting at their wide apertures, resulting in rugby ball bokeh pattern that swirls around the centre of the image. Noctilux vignettes more, but at least the bokeh is smoother and more pleasing. The optical formula of black S-mount 50/1.4 which were introduced in the sixties are a different formula, based on double-Gauss design.
