Canon Patent For Zoom Lenses For The RF Mount And APS-C Sensor

Canon Patent

Here is an interesting Canon patent application spotted by asobinet.com.

The Canon patent application seems to discuss optical formulas for various zoom lenses for the RF mount, and for APS-C sensors.

Not sure what to think about this patent. Any idea?

Are There Even Enough EOS 7D Users To Justify An EOS R With APS-C Sensor?

Eos R Model With Aps-c

We got a curios mail from a source we dealt with in the past. But instead of “never seen features” or “truly innovative sensor”, we got a somewhat different rumor. Well, it’s again about an EOS R with APS-C sensor.

Our source states, I quote, “do not believe the EOS R with APS-C bs [sic]”. Well, we never were sold out on this. However, the source, who claims to have some insights in Canon’s strategies, has a rather interesting argumentation for what he or she claims is Canon’s motivation to not release an EOS R body with APS-C sensor. Simply speaking, Canon doesn’t think there are enough EOS 7D users, or photographers with such needs, to justify the launch of an EOS R model with crop sensor.

To be honest, I never wondered how large the EOS 7D user base was. I know it’s a community with many happy with Canon for having made the two 7Ds. WIld-life photographers and all those on a budget yet needing more reach with their telephoto lenses made a thankful and reliable user base for the EOS 7D lineup. The question is: are they large enough in numbers to motivate Canon to design and build and EOS R with APS-C?

We had some discussion among us and involved some 7D shooters. While there was no clear consensus, we were able to agree (well, at least to a large degree) to the following points:

  • Full frame sensor equipped cameras are becoming more and more inexpensive. The EOS RP sells for less than $1000, and an upcoming new entry-level EOS R is rumored to be even less expensive than the RP. It’s no longer a financial hurdle as it used to be. Hence the motivation or need to safe a few bucks with an APS-C sensor might be decreasing.
  • Th same applies to telephoto lenses, for instance see the rather unexpected telephoto lenses Canon made with f/11 and sells at a reasonable price
  • RF mount lens offering is increasing quickly. No doubt about that, just look at sheer number of patent application.
  • For everything amateur level or below an EOS 7D, there is the hugely popular EOS M lineup, which I assure is not going to die anytime soon.
  • APS-C technology doesn’t seem to have a great future in the industry, besides on consumer cameras or where space issues and form factor are a critical issue.
  • And finally, Canon released the EOS 90D, an APS-C DSLR already far superior to the EOS 7D Mark II and seen by many as the last favor done to hard core professional APS-C shooter before taking them to Canon’s new shiny full frame mirrorless universe.

We are not saying APS-C will disappear in the next few years. The technology still has great potential and given how much crop sensors have evolved with respect to high ISO/noise performance, I am sure we are going to see some very interesting application in the future. Also, keep in mind that if full frame imaging sensor are going to cost less, this is even more true for APS-C sensors.

Curious to learn what you think.

Will Canon Give Up The EOS M Lineup After 2021?

Canon EOS M50 Mark II

Bad news for those who like the EOS M system, myself included. A new rumor suggests Canon might not continue the EOS M lineup after 2021.

The EOS M mirrorless system has already been declared dead many times. Now it seems it might eventually happen. According to the rumor, Canon will end the EOS M lineup in favour of two upcoming RF mount cameras with a APS-C sensor (so far only one EOS R with APS-C was rumored).

It’s also rumored that Canon might not release dedicated RF-S lenses (i.e. lenses for the RF mount but only for APS-C sensors). Instead, future lens design will “fill the void of no dedicated APS-C lenses”. Whatever that means. Guess it means that they are designed to work well for both APS-C and FF EOS R cameras. Sort of compromise? The upcoming RF 18-45mm IS STM might be the walk-around lens for an EOS R camera with APS-C sensor.

There will be EOS M cameras on market after 2021, and the EOS M50 Mark II won’t be the last EOS M camera. Stay tuned.

Canon Patent Shows RF Mount Zoom Lens That Could Be For An APS-C EOS R Camera

Aps-c Eos R

Interesting Canon patent application. Various zoom lenses for the EOS R system are discussed, with one being particularly interesting since it seems to point to an APS-C EOS R.

Canon patent application (2020-170102, Japan) discusses optical formulas for zoom lenses for the Canon EOS R system. The patent literature discusses the following zoom lenses:

Example 1Example 2Example 3
Focal length24.72-67.9024.72-116.4024.72-101.85
F value4.124.04-7.314.29-7.31

Look at example 5

As you can see from the table above, there are 24-70mm, 24-116mm, 24-100mm, 27.80mm, and, listed under “Example 5”, a 15-70mm f/4-7.1 zoom lens with an image height that doesn’t work for a full frame sensor on a mirrorless camera. However, the lens is based on the same design principles as the others, so it might be for an APS-C EOS R camera.

If you have a better understanding of the patent (or of Japanese), spotted by asobinet.com, please help me out on this. Is this really a lens for an EOS R camera with an APS-C sensor??

Canon EOS R With APS-C Rumor Surfaces Yet Again (now it’s 2021)

Canon Eos R With Aps-c

Some rumor are surprisingly smart when it comes to the perfect timing. The long running and now-and-then surfacing rumor about a Canon EOS R with APS-C sensor seems to belong to this category.

Just a few days after someone suggested Canon might kill the EOS M lineup, someone else suggests that Canon will release an EOS R model with crop sensor.

We always had a hard time to buy this rumor, independently of the source. The Canon EOS M lineup is well established, has a fond user base, and is a best seller with the EOS M50. So why the hell should Canon kill the EOS M lineup? And why should they come up with an EOS R camera with APS-C sensor? Wouldn’t even further fragment their offering?

However, the EOS R with with a crop sensor gets shifted fro year to year. It’s now rumored for 2021 but I bet in 8 or 10 months it will be rumored for 2022. I migth be wrong but I call the EOS-R-with-APS-C nothing but a fantasy (or bs, your mileage may vary). If someone has a compelling argument for such a camera, I’m listening.
