I've been going through my old camera gear planning to sell some stuff. I was set on selling my EL-Nikkor 50mm f2.8 enlarging lens until I saw the dismal resale prices for them. I don't really imagine myself spending time in the darkroom anymore...I'm one of those who is more than happy to put that behind me, but back to the topic and more importantly, the Question: What other uses might I put this lens to? Would it be good for any sort of macro or copy photography? On bellows? Reversed? Other creative possibilities? Or, should I just admit that it's not worth much anymore and let it go? (e-bay sales have been as low as $25 recently) Thanks in advance for your suggestions!
