I must say this is very good iniciative !
Maby in time more people would do that, some lenses are cheap but they have sentimental value. especially if you know that lense you get is from person who wanted you to have it
I would really use this lense. I have DA 50mm f1.8, but would use this lense for film and macro purposes. When i became pentaxian i have a dream to try film photography using pentax me super or other vintage pentax camera.
Oh, and i think jwc77 should make condition that if person who gets the lense and gets bored, do not put it in the drawer or darkest corner
but give it away someone else who needs it for free.
