Hello everyone, good morning, kindly, I have a problem with a Canon EF 70-300 IS-USM lens that I cannot understand.
In the photo that I am attaching you can clearly see what happens when equalizing a photo taken with this lens, they are all like this.
All photos like this are discarded for "vignetting not allowed".
The file for peripheral light correction is correctly installed on the camera.
I tried removing the file and reinstalling it but the result doesn't change.
I then tried to remove the vignette using Canon's DPP after loading the peripheral light correction file for my lens: setting it to maximum only lightens the edges but the bulk of the vignetting remains.
So I tried using Camera Raw's Vignette Removal but the result is identical, the vignette is not removed.
This problem is present only with this lens, with other optics I have no vignetting problem and it occurs throughout the excursion of the lens, from 70mm to 300mm.
I asked photographer friends but no one has any idea what the problem might be.
I also went to some specialized stores showing photos, but no one was able to give me an explanation
Has anyone ever had this problem with a lens?
Anyone have any idea how to solve this problem?
Thank you all in advance for any answers,
with regard
Carlo
