What about the Canon RF 85mm 1.2L USM DS?

We know this lens was one of the lenses that Canon announced development for back on February 14th of this year.  From a forum posting, we have from what I can gather is the only sample image I've seen comparing the two RF 85mm lenses in terms of bokeh.

You can see in the sample image the difference in these two lenses.

DS is a Canon term for something similar to an apodization filter.  In this case, Canon applies a specific coating to two of the elements to give the effect of an apodization filter.

According to the post, this lens is expected out in the second half of this year.

Update, we found a Canon USA article just posted on the Canon 85mm 1.2L USM DS and the differences, and where these images came from.

From the article we learn more about the DS lens and the differences to the 85mm 1.2L USM;

  • Reduced light transmittance: 
    The Defocus Smoothing coatings in the 85mm F1.2 L DS lens will reduce actual light transmission by up to 1.5 stops, when the lens is at its widest aperture.
  • Defocus Smoothing effect is aperture-dependent:
    The visual impact of softer-edged, out-of-focus highlights, is at its maximum when the DS lens is shot wide-open. The visual impact of Defocus Smoothing diminishes, vs. the RF 85mm F1.2 L lens, as the DS lens’ aperture is stopped-down, and essentially disappears if the lens is stopped-down several stops from wide-open.
  • Depth-of-field is rendered differently
    At wider lens apertures where the Defocus Smoothing effect is visible, for technical reasons, depth-of-field will appear deeperin shots taken with the DS lens, vs. identical shots taken with the RF 85mm F1.2 L USM lens.
