TPF Noob!
A couple days ago I was doing some preliminary photos for a shot I planned to do later on in my "studio." Now I've always known that I had a bit of dust in my lens (on the first group of elements under the outermost lens of my 18-70 Nikkor), but it had never given me much trouble... until now, when I added 56mm of extension and shot at the minimum aperture:
I take good care of my lens, so I have no idea how I got all that dust in there. Is there any way to get the interior of the lens cleaned? It's pretty much impossible to do macros now...
