Hi all, quick question. I took a picture with my 20D and kit lens at full wide and the pic had black in all four corners.
What has this? Some type of vignette?
Any ideas

Try the same types of shots with and without the filter (same 18 mm, f-stop, etc). I think you'll see a significant difference. Tom
