I'll second this and take it a step further. If you can part with the original cost
of the lens, you can ALWAYS get what you paid and sometimes a few dollars
more than you paid when you sell it.
It's almost like renting lenses, except you get to keep them if you want.
I am about to sell a bunch of lenses and pick me up a 17-55mm 2.8. It's gonna happen.
