The new Canon technology allows for unusual, soft bokeh. It was used in the latest lens of the manufacturer, and soon it can reach other glasses.
The RF 85mm F1.2L USM DS lens designed yesterday uses a new technology that provides custom soft bokeh. Will it become more popular and will go to more lenses? The manufacturer explains how the Defocus Smoothing function works .
How do you get soft bokeh?
Already over two years ago Sony showed the FE 100mm F2.8 STF GM OSS lens, equipped with an apodization filter, guaranteeing non-standard bokeh, characterized by soft edges. Now Canon has obtained a similar effect (or even more visible). The new technology called Defocus Smoothing is difficult to describe in a simple way, which is why the manufacturer has prepared a film in which he explains how the new technology works. However, the question arises as to how technology will affect the quality of photos taken. Will the lens let in less light? This is the case, for example, in the mentioned Sony lens, where the aperture is in practice twice as dark as the one we choose, because the apodization glass in this case works like an ND filter. Has Canon eliminated this problem and thanks to that the lens will get as much light as a wide-open aperture?
Will it work?
Another puzzling issue is the optical quality of the photos. Will the technology used not result in slightly increased vignetting? In short, we have several threats that this technology carries. The question is how the manufacturer managed (or will succeed) to deal with them. We will get the first answer when the glass appears on the market and we will be able to see real photos taken with the lens. The fact is, however, that if this technology is adopted, then soon we can get a completely new bokeh, so different from the one we are used to.
