Will RF Telephoto Lenses be Big Whites?
The title says it all. Will they make their telephotos superb and tough like the EF ones?
We’re told that Canon will be using the brand new Sony IMX571 image sensor in an upcoming Canon APS-C ILC camera body. The source thinks it’s going to be in a mirrorless camera, but there’s also the possibility we’ll see it in a DSLR.
The Sony IMX571 is a back-illuminated 26mp CMOS APS-C image sensor built for DSLRs, which we believe includes mirrorless ILC applications. The sensor is also capable of shooting at 16fps.
Canon has used Sony image sensors in PowerShot cameras in the past, but I cannot remember the last time they used a 3rd party image sensor in an interchangeable lens camera.

From Tokina:
We have thoroughly tested all current Tokina interchangeable lenses (Canon EF mount) with the Canon EOS R mirrorless camera and the Canon EF-EOS R mount adapter.
The results confirm that the current Tokina lens models showed no issues in general operations, with the following exception:
Tokina AT-X 17-35 F4 PRO FX
Issue: the image Cropping/Aspect ratio would be fixed at “1.6x (Crop)” and cannot be set at “Full (3:2)”.
We are currently preparing a firmware to fix the issue, which will be specifically notified about in due time.
Furthermore, when using Tokina APS-C format lenses (Tokina DX lenses), in case the Cropping/Aspect ratio is set otherwise, it is necessary to reset it on “1.6x (Crop)” manually. When shooting with a different Cropping/Aspect ratio setting, vignetting is likely to occur.
For any questions about the compatibility of Tokina interchangeable lenses with Canon EOS R mirrorless cameras, please contact us via the...

A good source has chimed in on the possibility of a Canon EOS R body with an APS-C sensor.
In a recent interview, a Canon executive made a comment about the EOS M and EOS R systems, saying (google translated) “Since EOS R is a full-size system, it can not be downsized to EOS M size. EOS M has a role/existence value as an APS-C system.”
A few sites took that to mean that there would be no APS-C sensor equipped EOS R body. We took it to mean that they cannot shrink the RF mount and the ergonomics needed for a “prosumer/professional” camera to the EOS M size of a camera and that a compact APS-C system like the EOS M would continue to exist for the foreseeable future.
Back to the source. We’ve been told numerous times in the past and again this week that at least one APS-C equipped camera is currently being developed and tested.
Why do we believe this? The EOS 7D series of...
Japan Patent Application 2018173487 shows a bunch of different optical formulas for new EF-M zoom lenses.
Lenses included in the patent:
EF-M 15-130mm f/3.5-6.3 IS STM
EF-M 18-130mm f/3.5-5.6 IS STM
EF-M 18-200mm f/3.5-6.3 IS STM
According to Canon News, the major focus of this patent application is making lighter focus groups, which would improve AF performance and prevent “wobble”, which would be important for video work.
BCN rankings have released the latest numbers for the full frame mirrorless camera market in Japan, and Sony’s near 100% market share took a big hit after the release of the Canon EOS R and the Nikon Z series cameras.
Full frame mirrorless market share breakdown (Japan):
Sony 67%
Canon 22.1%
Nikon 10.4%
Sony – Blue // Canon – Red // Nikon – Green
These numbers may be inflated since Canon and Nikon just released their full frame mirrorless systems. It’ll be interesting to watch over the next few months whether or not Canon and Nikon can maintain or even increase their market share in the segment.
If we had to make a prediction, Canon will likely have 50% of the market by this time next year once they’ve released a few...







The-Digital-Picture has completed their review of the brand new Canon RF 50mm f/1.2L USM. The first L prime for the Canon EOS R system. It’s big, it’s expensive and it’s pretty, but does it perform?
Bryan seems to think so:
A great 50mm prime lens has been high on the want list for many photographers and with the RF 50mm f/1.2L USM Lens, Canon has delivered big. While the price may keep such a lens on the want list for those with a tighter budget, many serious amateurs and professionals are going to find this lens to be an essential part of their kit.
The 50mm focal length has great general purpose utility and the ultra-wide aperture extends this lens’ versatility to ultra-low light levels. Just having an ultra-wide aperture does not mean that the wide-open image quality will be adequate for your needs, but there is no worry when using this lens at f/1.2. The resolution and contrast are great, far better than any...
The last month or so has seen a steady stream to our inbox of EOS R and RF mount information. Some will obviously be wishlists, but some of the information will be accurate.
We’ve been told on multiple occasions that an RF mount video product of some kind is in development. While only one of the comments mentioned a Cinema EOS camera, a couple of others said it would likely be outside of the Cinema EOS in its first iteration.
Most of the people we have talked to seem to agree that we won’t see such a camera until 2020 at the earliest, and not to expect this kind of hardware announcement for NAB in April of 2019. The RF mount needs more native lenses before an RF mount video product makes sense.
That said, I do wonder how many video shooters would appreciate an RF mount video product just to use the RF to EF filter adapters.
