Lenses and scratches
I've always wondered how scratches on the front element of a lens affected image quality, and to a certain extent even dust and smudges. For example - ever looked at a second hand lens and debated whether to buy it because of noticeable scratches or marks on the glass?

Well this guy gets practical in testing the scenarios above out - from smudges to "dirt" and dust, to actually scratching his zoom lens, and for the final test - breaking the front element altogether. At each stage he takes photos and pixel peeps to see if the image quality is affected.

I won't ruin it for you but very interesting reading indeed...
