Portrait photographer and YouTuber Alex Barrera recently went out and shot a full side-by-side comparison of the Canon RF 85mm f/1.2L and the RF 85mm f/1.2L DS lenses. His sample photos can help you decide if Canon's "Defocus Smoothing" is worth the loss of light and the extra $300 it'll cost you.
Does that photo of the new Canon 85mm f/1.2L DS IS lens look a bit dark to you? Well, that's because the new Defocus Smoothing coating Canon applied to its latest prime lens isn't without its tradeoffs. Though the Defocus Smoothing that helps improve the look of bokeh in photos, it's going to cost you a stop and a half of light wide open.
Canon announced the new RF 85mm f/1.2L DS IS lens for its full-frame mirrorless cameras today, and the $3,000 lens is the very first Canon lens to feature a new technology called Defocus Smoothing (DS). If you're curious about the new lens tech, check out this 1.5-minute video by Canon that introduces it.
Canon has announced two new RF lenses: the RF 70-200mm f/2.8L IS and the RF 85mm f/1.2L DS IS. Canon says these two lenses complete the "trinity" of RF lenses for the EOS R full-frame mirrorless camera system.
Canon is apparently getting ready to introduce a new lens technology to the world. It's called "defocus smoothing," and it'll appear as a DS feature abbreviation on future lenses.
