vignette problem quick fix

[Eric Pascarelli]

Ken, I understand you line of reasoning, as I had considered that theory myself. But empirically, the vignetting in my camera, which seems to be a "classic" case, is identical with or without the hood fitted.

Also, as I mentioned before elsewhere, when vignetting occurs in front of a lens, as caused by a hard matte or filter ring or whatever, it generally worsened at a tighter stop, at the offending opaque object becomes sharper. In this case, the vignetting becomes worse with a wider stop, implying a blockage closer to the iris.

Sorry for bumping this misleading thread to the top.

Ken,

Everyone who has the stated vignetting problem has removed the hood. The vignetting is still there. Brian is the only one here who mentioned his was the hood.
Again, while staring at my monitor (SD out full raster) clearly showing the problem, I removed the hood and the vignetting is still there.

Therefore, mine is NOT the hood.

Gentleman, Thanks for the help in pushing me to test further. After playing
back a clip that I knew had the problem I noticed I wasn't now seeing it which pointed to user error. My bad. I had moved to my laptop for viewing and did not have overscan view on! My "quick fix" post was indeed my error as I do see the issue now with ALL the samples < And I did alot of them > both with and without the shade. Not being able to see it on a clip that I KNEW had it was what made me look at the obvious..... Add another bad camera to the list.
