Auction is easier from your end as it's just mail it to the highest bidder.
Raffle is more inclusive as it's more affordable, but you do then need to keep track of who has bought how many tickets in order to find a winner!
Incidentally, most if not all of those lenses will still fit a modern digital Nikon body so if any Nikon users are after some good glass, they should enter, too!

Thanks for the input. I keep wishing they'd make a digital back for the FM2, but maybe I just needed to look at a DSLR body. Honestly though, my pixel phone gives me most of the photo power I need/want anymore.
