HD Camera Lens Icons

Hi there!
I had some of free time, and I spent it on making this 'high definition' Camera Lens Icon.
You can use it for anything you want, but I would really appreciate if you could left me some infos what it was used for
Every icon is saved as png file with transparent background, in following resolutions:
512 x 512
256 x 256
128 x 128
64 x 64
48 x 48
32 x 32
compressed in .zip file, which you can download.
If someone is interested to receive a .psd file, please let me know!
