P: Lens Correction Profile for Canon RF24-240 exhibits edge artifacts.

The update introduced, and set as default, a version 2 lens correction profile for the Canon RF24-240 lens which causes the Raw image to display incorrectly by showing an area outside that of the matching camera Jpeg which is blurred and distorted (I have only found this for images shot at zooms of 38mm upwards). This region can of course be cropped out as it is not part of the intended image. Reversion to the previous profile removes the problem.

My Lightroom Classic has been updated to 13.4 but now I find my raw files .CR3 files are showing a boarder of streaked colour (top and bottom are Vertical, either side are horizontal). Didn't happen before the update and if I go back to an image taken and imported before the update it doesn't have this border. Funnily enough one image in the set of 18 i imported taten in the same session doesn't have the border. I shoot in RAW and JPEG and none of the JPEG images have this border.

Any assistance would be appreciated.

Are these new imports showing up in the develop module with a lens correction (in lens correction panel) despite no such mod by you? ( and no lens correction in history panel)

Hi GoldingD,

Yes since the latest update of Lr Classic to version 10.4. From other posts I believe it is an issue with Adobe's update to the Canon RF 24-240mm F 4-6.3 IS USM profile to v2. When I change back to the original profile in the Lens Correction tab all good.

Zdjęcia po imporcie do LR na krawędziach są rozmazane. Już myślałem że to jakiś problem z aparatem ale te same zdjęcia otwarte w bezpośrednio w systemie Windows czy Mac są poprawne. Aparat Canon R6, LR w wersji 10.4 Camera Raw 13.4 Jakieś pomysły co mam gdzieś źle ustawione. Dodam że problem występuje zarówno w Win jak i Macu.

The right side of the screen capture appeals as if the RAW file that was imported is corrupted, this is usually a hardware problem, card reader, USB cable, RAM, HDD etc.

Ale wtedy chyba byłyby źle widocznie wszędzie, to znaczy nie tylko w LR ale też w innych programach. Tymczasem przeglądarka systemowa zdjęć wyświetla je w poprawny sposób.

After latest Adobe updates Canon RF 24-240mm f4-6.3 IS USM lens profile works wrong.

There is in Camera Raw now two profiles for this lens and profile "Canon RF 24-240mm f4-6.3 IS USM v2" brings

pictures outer bordes some distortion. Profile whithout v2 works fine. It seem to be so that v2 is default profile and it affects also in Bridge.

Is there coming fix for this problem or can profile whihout v2 install to a default or remove v2-ending?

I am using Canon RP body with latest firmware.

Not sure I fully understand. You have two profiles, one works fine, the other doesn't right?

So what is the issue using the one you feel works 'right'?

Is it possible there are two 'flavors' of this lens and one needs to use one or the other profile?

Hi,

I have had earlier no reason to change lens profiles. Now that v2-version is default profile and it´s wery irritating open picture on Bridge when it use that wrong profile. Ofcourse i can change it on Camera Raw but profile shoud not be working like this. I have laptop and a desktop computers and both start working same way today. I am sure that this is driver problen on software itself.

It would had been nice to know from where that v2-ending came from!

I will wait fixing software update. And if you have any fixing ideas i am very please to hear it.

I will attach two pictures from that issue.

Hi Folks,

Which Canon body(ies) are you seeing this behavior with?

Thank you.

I see it also... M1 MacBook Air. THANK YOU for posting this. I'm about to leave on a long trip covering an event where I will rely very heavily on this camera/lens combo. Glad I'm learning about this now rather than after importing hundreds of images the first day. I would have been in major panic mode. No big deal now that I know what it is and how to correct it.

I can confirm this behavior with LrC 10.4 and ACR 13.4 on my Windows 10 system using the v2 lens profile. The original (v1) lens profile does not exhibit the issue.

I am using the most recent updated versions of LR ( ver. 10.4) and PS (ver 22.5.0). Yesterday's update has caused some weird artifacts on the edges of all my photos.

System is MacOs version Big Sur 11.5

Macbook Pro 2019 16"

Camera: Cannon EOS R6

I have uploaded photos to Affinity and Digital Photo Pro 4 and the artifacts don't appear. They appear in both PS and LR and are present on all my lenses and throughout the range of each lens. Rarely seen in the sky portion of the photo but always seen in the bottom and both sides. Attached is a cropped version of the left and bottom side of a photo. Oddly enough, it does not happen if I shoot JPEG, just RAW files. I am now having to crop a considerable bit off the sides and bottom of all my photos.

Has anyone else seen this problem?

Wanted to add additional information. I uploaded two photos from my husband's Pentax and the lines don't show up there. Could it be something to do with Cannon CR3 files? I have had no problem until the latest update.

Here is the crop of one of the photos. Hopefully you can see the lines on the bottom and left side. I have eliminated corrupt files and corrupt SD cards. I will not go through the steps I took but you will just have to trust me that the problem is with Adobe. I went back and uploaded some files that I took pre-update and they are now showing the lines too. Went back and looked at all my settings and found that if I uncheck "enable profile corrections" it will remove the lines but crops the photo. If the photo doesn't have lines (seems to be alright at 24 mm focal length) and I uncheck the box, it leaves a really horrible vignette on all corners. I appreciate your thinking it may be a hardware problem but I am really doubtful as I have had no problem prior to the latest update. I have and use two different SD cards and that makes no difference. Thanking you all for trying to help. It is certainly a frustrating problem.
