Hi,
I am new to this forum, but I have been following the website for last few years. Just needed a little help regarding my new lens 24-105 f4. I just got this lens a week ago, but in most of the images, esp taken wide open, there is darkness/shadows at the edges/corners. I think there is a way to correct it. If someone can help, it will be appriciated.
Thanx
Amir
