Canon EOS RP Review – Still A Valuable Camera In 2021

Canon Eos Rp Review

The less expensive of Canon’s full frame mirrorless cameras gets little attention nowadays. Here is a Canon EOS RP review, and why it is still a valuable and capable camera.

At a glance:

  • 26.2MP Full-Frame CMOS Sensor
  • DIGIC 8 Image Processor
  • UHD 4K and Full HD 1080 Video
  • 2.36m-Dot OLED Electronic Viewfinder
  • 3″ 1.04m-Dot Vari-Angle Touchscreen LCD
  • Dual Pixel CMOS AF, 4779 AF Points
  • ISO 100-40000, Up to 5 fps Shooting
  • Wi-Fi and Bluetooth Connectivity

Jacek Sopotnicki posted a Canon EOS RP review that looks at the value this camera has in 2021. And we agree: there is plenty. The Canon EOS RP was announced in February 2019. Not even that old, but I guess two years are a lot in MILC world.

The Canon EOS RP starts at $999. More Canon EOS RP review stuff is listed here.

Canon Might Announce 2 Tilt-shift Lenses (with AF) Along With A High Res EOS R Model

New rumor has it that Canon is set to announce two tilt-shift lenses with auto-focus for the RF mount and a high resolution EOS R model.

Canon Rumors reports that Canon will announce two tilt-shift lenses for the RF mount. These would be the first tilt-shift lenses with autofocus: Canon TS-R 14mm f/4L and Canon TS-R 24mm f/3.5L. No other specifications about these lenses nor do we have a clear announcement schedule. However, we think it is safe to assume Canon will indeed release these lenses, maybe towards the end of 2021 or beginning of 2022.

As for the high resolution EOS R we already know that it is coming. Indeed, such a camera is rumored since a while. Latest rumor suggests a sensor resolution of more than 100MP, previous rumors suggested a resolution between 80MP and 90MP. It’s not clear if we can expect the high resolution EOS R in 2021.

Stay tuned.

Full Frame Outperforms Medium Format: Canon EOS R5 & 85mm f/1.2L vs Hasselblad 80mm f/1.9

Eos R5 8k Video

Once more the Canon EOS R5 shows how innovative Canon’s latest imaging sensors are. The R5 full frame sensor paired with some of Canon’s best RF mount glass outperforms a medium format system.

The folks at Sonder Creative compares the Canon EOS R5 with the RF 85mm f/1.2L lens to the Hasselblad X1D II with the XCD 80mm f/1.9. Well, it seems the full frame EOS R5 outperforms the medium format Hasselblad X1D II.

More Canon EOS R5 review stuff is listed here, for EOS R6 review stuff see here. The EOS R5 is highly regarded as a stills camera. In particular, the EOS R5 autofocus system seems to be huge leap forwards. User manual are available for download for the EOS R5 and the EOS R6.

Interview: EOS R3 Not Flagship, Sensor Developed By Canon (and made by Sony?)

Canon Eos R3 Specifications

Some interesting bits about the Canon EOS R3 in an interview with a Canon Russia exec. Who makes the EOS R3 sensor?

We wonder who makes the Canon EOS R3 sensor, after a change in wording on Canon UK’s site: from “designed and manufactured by Canon“ to “developed by Canon”. Does it mean something?

Russian site PhotoWebExpo interviewed Mr. Andrey Tishchenko, Canon Russia’ Head of Product and Consumer Expertise. The question about who makes the EOS R3 sensor came up. The answer leaves us a bit puzzled. So, let’s start with the excerpts about the imaging sensor (emphasis mine, text is machine translated):

Q: Will the Canon EOS R3 get a new sensor? Or will it be similar to the one in the Canon EOS R5?

The sensor is new because we have already stated that this is the first backlit Stacked Sensor BSI we have developed ourselves. […]

Q: Is this Canon’s first stacked sensor? 

Full-frame format yes, but in fact, one of the most popular compact models in the PowerShot series, the Canon G7x Mark III has a 1-inch Stacked CMOS sensor. That is, such technologies have already been applied in our cameras, but it is the Canon EOS R3 that will receive the first full-frame sensor of this technology. 

Yes, the PowerShot G7 X Mark III has a stacked sensor, and it’s made by Sony! Does this fact suggest the EOS R3 sensor was developed by Canon and manufactured by Sony? Remember that Canon UK changed the text of the EOS R3 presentation in a significant way.

There is more in the interview. The interviewer also asks about the flagship in the EOS R lineup:

Q: Why R3 and not R1? And should we expect a mirrorless replacement for the 1D X mark III, which was recently introduced?

The Canon EOS R3 will be a brand new camera lineup that will sit below the 1D X Mark III and above the Canon EOS R5.

The Canon EOS R3 does not exactly replace the 1D X, nor is it a flagship. And I think the 1D-X Mark III will be the most popular camera at the upcoming Tokyo Olympics, which I hope will take place. There you will see who is shooting what and the “one” will definitely become camera # 1.

Unfortunately, we cannot comment on the company’s plans for the release of new cameras.

When asked about the rumors claiming that Canon will retire the EOS M lineup:

I cannot talk about the prospects for the development of the Canon EOS M system. At the moment, the system is well equipped.

Canon Might Release a 60mm f/1.0 Lens For The RF Mount

60mm F/1.0

A rumor popped up in our inbox: Canon working on a RF 60mm f/1.0 lens. Plausible?

We did not get any specification for the allegedly upcoming RF 60mm f/1.0 lens. we are a bit out in the rain here. Also, we are a bit surprised by the focal length of 60mm instead of more common 50mm. Wouldn’t it make more sense to bring the legendary Canon EF 50mm f/1.0L to the EOS R system? But maybe the optical design possibilities offered by the RF mount suggest a 60mm is the better option. In any case, it wouldn’t be the first time Canon surprises us.

All in all we think an RF 60mm f/1.0 is definitely possible. Having already an optical masterpiece with the RF 50mm f/1.2 it would probably not make much sense release another optical masterpiece with the same focal length and the “only” benefit of having f/1.0 vs f/1.2. A new 60mm lens would be a different matter, I guess.

All ideas are welcome.
