RF 24-240mm F4-6.3 IS USM Blurred Edges on Multiple Cameras

leighsandlin — Sat, 24 Aug 2024 12:58:11 GMT

Can someone suggest what might be happening to the edges of my pictures? This picture was taken using an eos r6 mark ii, but I had the same result with eos r8 last week. Lens was rf 24-240. The upload makes this picture look like the whole thing is soft, but it’s actually sharp - the problem is just the edges.

had the same result from an eos r8 last week…photo taken with rf 24-240 lens.

Glad to hear it! In case someone else comes along with the same problem, would you mind letting us know how you fixed it? That could really help someone else out in the future!

I recently began having the same problem with blurred borders to my photos using the RF 24-240mm F-4-6.3 IS USM. I don't notice this at the shortest focal lengths, but anything over about 40mm has this problem. My camera is an R6 MII. I purchased the lens in May, and it did not develop this problem until very recently. I don't have this problem when I switch lenses. I see short, narrow, colored lines perpendicular to the border. They remind me of color bars in a test pattern. Sometimes I see the lines around the entire border, and other times it is apparent on only two borders. Does anyone have any suggestions? Unfortunately, I have not figured this out on my own.

This is apparently a Lightroom issue. I changed the LR lens profile from the most recent V3 back to V2, and the problem went away. I see that I am out of date on the firmware for my camera. I will update that and see if the lens profile V3 works properly.

I have had the same issue with the current version of PS, so I would suggest it is likely Adobe's lens correction software that is the issue.

I am not sure I would go with LR as the problem, could be but FIRST get a new SD from a known good source and a top brand. I can't ever remember LR doing or causing that.

I als doubt FW is the issue unless it address updating or installing a new lens, your specific model.

Your lens has a zoom ratio of 10:!, the ratio of the longest focal length to the shortest FL. That puts it in the category of super zoom in my book. Super zooms are not known for having great edge to edge, corner to corner sharpness.

The best zooms have zoom ratios of 3:1 or less. The laws of physics will always prevail.

I found an extensive discussion about this topic on the Adobe Community. It is, in fact, a problem in moving from V2 to V3 of the Adobe lens profile for the Canon RF 24-240mm. See: https://community.adobe.com/t5/camera-raw-bugs/p-canon-24-240-lens-profile-v3/idc-p/14834475

The fix for now is reverting to V2. Interestingly, I found the same discussion from 2021 in moving from V1 to V2 of this lens profile. The solution then, as now, was to move to the previous version. Eventually the bug was fixed in V2. This has been reported to Adobe, so presumably they will fix the V3 issue at some point.

It is a known Lightroom issue that has been around for years.

"It is a known Lightroom issue that has been around for years."

It's not known to me and I have just topped 96,000 photos in LR. I've never seen it.

Coincidence proves nothing except coincidence. Again topping 96k and never seen it.

It was a relief finding out that this was a problem with Adobe Lens Profiles that had an easy fix and not a hardware issue.

I am not a You Tuber, review reader or keyboard jockey and solely rely on what I experience myselt. Now I know there are mostly You Tuber's and review proponents on this forum, not hard to spot them, and I suppose that's not all bad it's just not me..

If it fixed the OPs problem great.

New update from Adobe that solves the lens profile issue for RF24-240.

I agree - it was an issue with Adobe lens correction profiles after a recent update and happened with a couple of RF lenses, but Adobe corrected it with a later update, so make sure your software is updated.
