Im I misreading ??

With adapters we will have a crop factor ??

so for example a 100-400 is really going to be a 120-420 ??

Did I read that right

The linked article in Mark0159 post 436 was quite informative!
The adapters themselves do nothing to switch crop factor. They merely allow the 44mm backfocus EF lens to be mounted on EOS R body with full functioning without loss of performance, Crop factor switching is with video (vs. still), or with EF-S lenses. No details about how the camera knows to switch to crop mode (for EF-S lens smaller image circle, nor details about how aftermarket lenses with smaller (crop) image circles are handled.
But in addition...

  • EF/EFS lens can be mounted on EOS R body with full functioning without loss of performance
  • EF/EFS mount lenses can be used with the EOS R style control ring on the control adapter
  • EF/EFS mount lenses can be used with an in-adapter filter

Even without any adapter, the EOS R lenses have higher speed communications between body and lens, and the EOS R body can perform some of the IS corrections in conjunction with in-lens IS corrections (Canon new patent that was filed in late 2017 and approved in early 2018)

Interestingly the EOS R can perform image quality processing tasks to further optimize IQ, but these can only be done
on JPG files stored in EOS R camera
RAW files if used in conjunction with Canon's DPP software

Im just curious with this release if you wanted to stay canon why would you choose the r over the 5d4?

An f2 zoom is something I'd love to play with, and it isn't even a focal length I'm wild about.


Godox/Flashpoint r2 system, plus some canon stuff.

Certainly exciting, until you realize the weight is 1430g then at that point you can shoot with a 35 f1.4 + 85 f1.4 on two separate bodies and not weigh a ton more and better look. If it were less than 1KG, I think it would be a lot more appealing.

The weight is pretty darn noteworthy. Same with the 50L. 1KG primes are real old. I wish the manufacturers would stay away from these mega sized builds when possible.

I think in my current use, I could easily go without IBIS. It is effective on my A7III BUT, I can only use it with one lens.

I have 3 adapter Canon lenses which all have IS and 1 native Sony lens. As I'm using the MC-11, I can only use IBIS if the attached lens doesn't have IS so it doesn't help me for my adapted lenses.

For the Canon adapters, I really love the drop in filters. It's a great idea and makes UWA lenses with a bulbous element much more appealing to users like me who always use filters. Performance wise I expect the to be flawless as when I use the current EF to EF-M adapter the lenses perform like native.

So do we have a form of IBIS when shooting video? Hmmm...

Movie Digital Image Stabilization
The EOS R includes Movie Digital IS offering 5-Axis Image Stabilization, which along with distortion correction during recording, make for a powerful combination of in-camera image correction tools.

The EOS R is equipped with an algorithm that corrects camera-shake blur in a high-precision manner, practically eliminating gyro-sensor noise created by the lens. The algorithm determines the amount of blur in image data sent from the CMOS sensor and uses this data to adjust the final image. If the attached lens has IS capabilities, the sensor correction process works in combination with the IS information on the lens. The results produce a slightly cropped image to allow for image repositioning.

When a lens (such as the new RF 35mm f/1.8 Macro IS USM) that supports Combination IS is attached to the camera, the in-camera Movie Digital IS and in-lens optical IS work in tandem via high-speed data transmission, to provide powerful Image Stabilization. This is referred to as Combination IS. When a non-IS lens is used, the camera’s 5-axis electronic Image Stabilization feature operates alone, suppressing camera shake to produce stable movie clips.

Check out the portion of this video...interesting. Maybe with a firmware update this can be applied to stills?

My assumption is that it's referring to "digital" stabilisation, rather than IBIS. I.e. the sensor itself isn't actually moving; instead the camera is looking at the contents of the captured frames and manipulating them in order to reduce shake.

There are video editing tools that will do this in post process - basically trying to determine if frame-to-frame movement is actually shake, then slightly cropping the frames, but with the crop window being adjusted on each frame in order to try to keep the image stable.

If done in-camera then they would have the benefit of being able to potentially access an internal accelerometer, and move that crop based on detected movement. How effective that is vs true IBIS I don't know.

I believe that even for stills there are sensor wells outside the area that form the captured image, but maybe not enough to achieve stabilisation. Depends on how much effective movement you need at the sensor in order to correct shake I guess.


Camera, some lenses, too little time, too little talent

Actually you could have two bodies with a 85 1.8 and 35 F2 for extremely lighter and better look still.

I believe it can be very effective for video, and I'm certain one of the action cams can do it.

There's always Warp stabilizer in post, but it's slow, intensive, hit and miss. Ibis + movement, is tough enough to stabilize in post, and often not good enough.

Would love IBIS + digital + lens. Stable video is so important in making watchable content.

That's why so many folks are clamouring for 4K60 and 1080/120. It's to give slow, cinematic movements. Slow motion is a great way to stabilize shaky footage.

IBIS has the advantage of working for video and still though. The digital system on the canon is for video only but it does work really well from what I've seen.

Jared Polin has made some RAW files available. He's pretty cool that way. He also mentions at the end of the video that the camera is "not what he expected and will leave at that" Hmmm... Remember, he's a Nikon guy.

Here is a 4 minute video running through the specs of both side by side. Lots of similarities.

I would agree with this statement if I knew what kilogram was. :twisted:

He used to be a Nikon guy but owns an A9 as well and also seems to have a 6D Mark II as well since he uses it for Timelapses.
