Canon Might Have a 50mm f/1.8 and a 28mm f/1.8 For The EOS R System On Their Agenda, Patent Suggests

50mm F/1.8

Canon patent application 2019-0113711 (USA) describes the optical formula for an RF 50mm f/1.8 and RF 28mm f/1.8 lens, both for the Canon EOS R full frame mirrorless system.

Focal length 48.50
F-number 1.85
Half angle of view (degrees) 24.04
Image height 21.64
Total lens length 95.00 
BF 15.80

Focal length 28.80
F-number 1.85
Half angle of view (degrees) 36.91
Image height 21.64
Total lens length 80.30 
BF 7.00 

It’s likely Canon will launch these non-L lenses sooner than later. Both are popular focal lengths on full frame, and it’s also likely Canon is set to offer some less expensive (aka budget) lenses for the EOS R system.

More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production in the next few years are these:

Canon Lens Designers Talk About Latest RF Mount Lenses in Interview

Canon RF Lenses

DPReview sat down with Canon lens designers (Manabu Kato – Head of EF + RF mount R&D, Yoichi Sato – EOS camera electronics R&D, Shogo Yamaguchi – Optical planning specialist).

The interview was about the new Canon EOS RP, the six RF lenses Canon is set to announce soon, and in general what’s going to happen with the EOS R system.

Excerpts from the interview:

How do you prioritize which [RF mount] lenses to develop?

So the idea for the initial four lenses was we wanted to deliver the surprise factor, so we decided to deliver the 28-70mm, as well as the 50mm F1.2, with stunning resolution. That was the concept behind these two lenses.

With 24-105mm we thought it would be the best match as a standard zoom lens to the EOS R camera, and the 35mm F1.8 was supposed to be an affordable and compact travel companion. Those were the concepts behind the four initial lenses.

With the six additional lenses that we introduced as development announcements this time, we believe we will be able to deliver more surprise factors, for some models compactness. These two concepts with the addition of these models.

About the Defocus Smoothing technology.

Can you give any insight into the DS technology?

With lens such as the 85mm F1.2 bokeh is a really important factor, because it’s a portrait lens. We really wanted to deliver something that was not possible with the conventional lenses, so we decided to develop this technology of defocus smoothing.

The fact with our DS technology is that it’s a coating technology, so it’s relatively easy to apply this technology to a range of different lenses. This is all we can say at this moment.

Canon Might Release A Cinema Camera With RF Mount, In The Distant Future [CW1]

Eos C100 Cinema Camera

Rumor has it that Canon may have a Cinema camera with RF mount in the works.

However, such a camera isn’t to be expected before 2021, or even later. I have no idea if the RF mount is anything that would make something special out of Canon’s Cinema cameras.

Honestly, I don’t think we will see such a camera anytime soon, if ever.
