Here is a Canon RF 85mm f/1.2 DS review by YouTuber Artaius.

If you wonder what the “DS” stands for it’s for “Defocus Smoothing“, an optical technology exclusive to Canon. As you might already have figured out, Defocus Smoothing is about blurring out the background, getting a nice bokeh effect, and everything creative you can do with out-of-focus items. Another boutique lens for the Canon EOS R full frame mirrorless system.

Says Artaius:

The Canon RF 85mm f/1.2L DS (Defocus Smoothing) is the closest Canon will ever get to making a Lensbaby lens – its bokeh is just next-level wow. The question is, will it replace the standard RF 85mm f/1.2 as my favorite lens for the Canon EOS R? I put them through some side-by-side shooting comparisons to show you exactly how unique the bokeh is on this lens, and to help you decide whether it’s worth that 3K price tag. If you want to know the difference between the two lenses, this Canon RF 85mm f/1.2 DS review is for you!

Unfortunately this optical marvel is not an inexpensive lens: it sells for $3,000.
