Canon Patents 'Defocus Smoothing' Tech, Promising Game-Changing Bokeh for Portrait Photography

In the ever-evolving landscape of photography, Canon has again made headlines by filing a patent application that could potentially revolutionize the realm of portrait photography. The buzz around the industry is palpable as Canon's new "Defocus Smoothing" (DS) optical technology showcases their commitment to pushing the envelope of what lenses can achieve.

The technology in question is poised to alter the way we perceive out-of-focus areas in a photograph. By mitigating the abrupt contrast between sharp and blurred regions, DS technology promises a more harmonious and aesthetically pleasing transition, an effect particularly coveted in portrait work where the subject is the focal point against a diffused backdrop.

For the tech-savvy and the curious, Defocus Smoothing is akin to apodization—a principle that involves a graduated filtering approach, leading to smoother bokeh effects. However, Canon's innovation here lies in the implementation of a special coating applied to lens elements, a technique that manipulates light rays to achieve the desired softness in the out-of-focus areas.

The patent applications suggest a range of lenses, including the likes of the RF 70-200mm F2-2.8 DS and RF 70-135mm F2.5 DS, that could benefit from this technology. Moreover, Canon seems ready to offer photographers the choice between DS and non-DS variants, catering to diverse preferences and shooting styles.

But what does DS technology mean for the end-user? Essentially, lenses like the Canon RF 85mm f/1.2L USM DS are engineered to produce a distinctive and artistic look, something that can set apart professional portraits from the rest. The DS coating not only enhances the bokeh but also adds a unique flair to the imagery.

As for the advantages, users can expect lenses that provide not just a shallow depth of field but also a controlled and pleasing bokeh effect, thanks to the apodization-like element. Nonetheless, it's important to note that while DS lenses might offer a visual treat, they do come with a trade-off in light transmission compared to their non-DS counterparts.

The industry is also rife with speculation regarding the release dates of these lenses. While nothing concrete has emerged, rumor mills suggest a possible release date for the Canon RF 200-800mm lens and anticipated announcements for high-resolution camera models that could pair well with these groundbreaking lenses.

Canon's history of lens innovation is well-documented, and the new DS technology is no exception. It stands as a testament to the company's dedication to enhancing photographic artistry. For those eagerly awaiting to see these patents come to life, the anticipation is high. The photography community watches with bated breath as Canon continues to redefine the boundaries of lens design.
