Canon has some wonderful lenses for photographers, which they intend to grow with time. The RF mount is relatively young, and it has already introduced some great models. For instance, the VCM models are the latest addition, that are priced well, and work perfectly. Now, it appears the company is working on newer primes, which can be helpful for portrait, wedding, and event photographers.
According to Asobinet, the company patent P2026059152 showcases three designs of lenses: 85mm f1.4, 135mm f2, and 55mm f1.8. The lenses are designed to feature a compact inner-focus optical system, which can help to reduce aberration fluctuations.
Example 1
- Focal length: 82.50
- F-number: 1.85
- Half-angle of view: 14.69
- Height: 21.64
- Length: 97.83
- Back Focus: 15.33

Example 2
- Focal length: 83.17
- F-number: 1.46
- Half-angle of view: 14.58
- Height: 21.64
- Length: 118.00
- Back Focus: 16.00

Example 3
- Focal length: 131.00
- F-number: 2.06
- Half-angle of view: 9.38
- Height: 21.64
- Length: 135.06
- Back Focus: 16.29

Example 4
- Focal length: 55.08
- F-number: 1.85
- Half-angle of view: 21.44
- Height: 21.64
- Overall length: 78.50
- Back Focus: 14.00

The interesting part is that Canon already has four 85mm lenses. Two f1.2 variants, one f2 Macro, and one f1.4 VCM version. Each of these offer different price points and also works for varying groups. The f1.2 lenses are designed for portraiture and cost between $3000 to $3,300. The f2 is priced at just $589, while the f1.4 is priced at $1,650. So, another 85mm f1.4 does not make sense, unless, they are launching something for younger photographers that is priced under $600. However, and 85mm f1.8 can be ideal for those who want a cheaper alternative.
Then there is the 135mm, which already exists in f1.8 version. The lens is priced at $2,100 and it is pretty great. In fact, in our review, we stated:
There’s a special thing about the Canon RF 135mm f1.8 L. When you photograph with it, it’s very difficult to take a bad image. And you don’t understand — I mean that with all certainty. It’s not a lens that you’d use all the time. However, it’s hard to take bad photos with it when you use it. Everything you shoot will be considered for a keeper of some sort. That goes for the color, the bokeh, the overall light render, etc. I can’t say enough good things about this lens.
Keeping this in mind, a new 135mm f2 will either be a Macro lens, like the 85mm version, or will be more cost-effective, or alternatively, which may be priced under $700. Zeiss launched a 135mm f2 for DSLRs, so perhaps, Canon will introduce something similar. If it is a VCM lens, then it will be priced around the same as the 135mm L. It is unclear if Canon wants to revive a new version, given the original lens is announced in 2024.
Last but not the least is the 55mm lens. Usually, the 55mm option is used in kit lenses, such as 18-55mm options with EF-S lenses. Other than that, Canon offers various 50mm offerings, including 24-50mm, 50mm f1.2, and 50mm f1.4 options. So, a 55mm does not make sense, unless they are recreating something for APS-C cameras.
Moreover, these lenses, especially the 135mm, can help replace Sigma, Viltrox, or other third-party brands. Since Canon is protecting itself, this move could be good for them. The patent showcases these lenses, but it is unclear whether they will actually introduce the models. For now, the focal lengths chosen are too deliberate to dismiss.
