Recently bought two lenes:
50mm f1.4 and 100mm f2.8 Macro. I put a nice finger smudgeon the 50mm, so had to clean it up. And noticed there a number of tiny specks on the front element that will not come off. I mean tiny, as in shine a bright light on the lens to see them tiny, but tough! Feel free to wonder how it is I got a finger smudge on the new lens (I've thought it over, and determined I'm a goober)
So I took a close look at the 100mm, and noticed fewer, but still some tiny specks, and also what I assume is One Genuine Factory Installed Piece of Dust inside the lens (can a Rocket Blaster blow dust into the lens body by way of the two little vents at the fron of the lens?).
Of course these little items won't affect picture quality, but is it typical of Canon Lens/all Lenses? Should I even be lloking that close?
Thanks!
