I have a wide angle lens (12-24mm DX lens) and a telezoom (55-200mm DX lens), and they both come with the hood. I tried using the hood for the wide angle before, and I noticed at anything below 15 mm, it causes vignette on the corner, so I was curious what is the use for it at all, if I even need it. For the 55-200mm, I read on Ken Rockwell's site that it's really of no use, but wanted to see if anyone has any thoughts around the usage of lens hood for either lenses.
Thank you
