So I got a new r5 and an rf 100-500 in anticipation of going to Africa later this year. I am a professional photographer that normally used 5d mk4s for my day-to-day workflow.
Long story short. Here is a picture I took this morning with the above r5 and rf 100-500 combo. Both have the latest firmware.
The background looks like someone used a smudge tool or the liquify/push tool to push and pull the texture of the background around. I opened this photo in dpp4 and in the latest lightroom. Both programs show the same effect.
I am attaching a small jpg that has only been slightly sharpened to show the effect, but the photo was taken as a cr3. image was taken at iso 800, 500mm, f9.0 1/1600 of a second. IBIS and lens stabilization are on.
Obviously, this is not a great photo, but if it was it would be ruined by the effect taking place. has anyone else had this issue. I could upload the raw file if anyone knows a server that will host such a large file. I assume this site will not.
Any ideas? As of now I am a bit disappointed with the camera lens combo for being such a high-end rig, I was selling my nature kit (nikon D810 and 150-600) to go all canon. I am unsure of that move now. There seem to be a few other issues with the camera that I'm not sure I can live with.
Anyway, let me know if you have any ideas on what is causing this.
Thanks

The only thing that immediately comes to mind is if you have dual pixel RAW enabled? I never used that feature myself, so don't know if it would ever lead to such output.

Hi Ricky. Dual pixel raw is not enabled.
I never use it either.

You could take it up with them.
I don't see it in any of Ken Rockwell's images

Is this with or without DLO?

Looks like you're using a UV or CPL filter, to me. If so, switch to a B+W Nano Clear filter. But, take test shots with no filter to see if removing any filter you might have been using makes any difference.
[EDIT] I have also seen a similar pattern when I had IS turned with the camera rig on a tripod, or when holding it very still.

Waddizzle.
I'm not using any filters and the camera is handheld
I was thinking it might be an IS problem but why would different areas look different, unless there was some software stabilization going on. That's not my understanding of how this setup works.
Thanks

No. I'm not a member. I have considered joining a few times. I might have to.

You can see it up around the log in this one too. It has sharper areas and what sort of looks like motion-blurred areas and then some areas have a nice Bokeh. All of these areas are far behind the subject (feet) so it does not make any sense that there would be this inconsistency in the bokeh. I guess I will have to take this to canon because I don't find it acceptable. I've also noticed what seems like motion blur in slower-moving objects at 1/1600 of a second. Like some of the images have a double exposure look around the fish's eye, etc. Things that if taken with my other cameras would have been slightly out of focus but not streeked or motion blurred.
