After I was unable to find any answers from Canon or Tokina support and searching this forum, I thought I'd start a dedicated thread in the hopes that the gurus out there might be able to help.
I've used my Tokina AT-X Pro SD 11-16mm f/2.8 (IF) DX II for 7 years on my Canon 60D DSLR without any issues, but after upgrading to the Canon R10 mirrorless (FW 1.5.0) with the Canon EF-EOS R adapter I now experience some pretty severe chromatic aberration (CA). Samples uploaded to https://photos.app.goo.gl/tUqadN9B21GrXhcF8 and it's very noticeable in the astrophotography (5702). I don't always want to shoot in RAW and be burdened with the post-processing. Thoughts from the community on the root cause and corrective action?
More details:
- I did not see any CA issues with the Canon 60D DSLR and I only shot in JPG.
- My first trip with the R10 was to Antarctica with lots of high contrast white scenery and fortunately I didn't detect any CA (shot in RAW+JPG), but it has since started to appear and increase in severity.
- CA is present in the on-camera generated JPG. This is true if saving as JPG directly (5363, 5364, 5367, 5609) or on-camera conversion to JPG (5702).
- CA appears in unprocessed RAW, but then fortunately it will process out (Windows Photo or Canon Digital Photo Professional). Why can't the on-camera conversion correct this?
I'm also new to post-processing and wasn't able to find any lens correction data for the Tokina in Canon Digital Photo Professional. Could that possibly fix the CA better?
I appreciate Tronhard's post in https://community.usa.canon.com/t5/EF-RF-Lenses/Lens-recommendation-for-Iceland-travel-aurora-photog... about Sigma lens, so I'm eyeing the Sigma 10-18mm F2.8 DC DN to replace my beloved Tokina 11-16mm f/2.8 if I can sell that for a reasonable cost to justify the upgrade.
Thanks in advance for the help!
