Canon’s announcement of two RF 85mm f/1.2L lenses for their mirrorless camera system was quite surprising. One of them has that “DS” moniker, or “Defocus Smoothing” and the other does not. It was announced early last year, but what does it actually do? And how do the two lenses stand up side-by-side?

The DS version of the lens costs significantly more than the non-DS version, at $2,999 vs $2,599. But is it worth the extra cost? Does it really make a difference? In this video, photographer and YouTuber Christopher Frost takes a look at the two side-by-side in order to find out.

Canon recently announced the new RF 85mm f/1.2L USM DS lens for the EOS R mirrorless system. But what exactly does DS mean? Sure, it means “defocus smoothing”, but what effect does that actually have on the image? How does it make the bokeh look? Well, Canon has put out a video showing exactly how it looks.
