I just sold my 70-200 F/4 L lens last night for $350. I let it go for that price because there was dust in the lens, which I have no idea how it got there.
So now I can pay some of my CC debt from my macbook pro off, which would enable me to buy the 70-200 f/2.8 IS L sometime!
I have been organizing my photos from 2004 till now into better categories. So… I am pretty busy!
