Hi everyone!
These have been slow days down here so I've had enough time to test some things and I came up with this, may be I will sound silly but the fact is that this issue is now answering some questions.
I use a Canon 35-350mm most of the time and I use a UV Haze filter to protect the from element, well, today I remove it just for fun and see how it affects an image, and man, it really affects the image!
I want to know if some of you guys that are reading this, use filters stack on your lens, and if you do, why? protection? or something else.
Thank you all for your input.:D
