Just a generic lens for photo manipulation softwares.
[EDIT] A google search shows me that some people have been using this image without my consent for commercial projects and have made a amateur graphic designer very sad. *makes a sad face*
This image is now going fully under the safe wings of copyright protection. No more derivative works and no more commercial use sorry!
Write to me at firstname.lastname@example.org to get my written consent if you are to use this for non-commercial/personal/student project. You are still, of course, very much welcomed to download this and use it on your own computer/mac or whatever
I am also putting this up for sale, so contact me if wish to do so.
