I'm thinking of drastically paring down my somewhat bloated collection of FD lenses (as well bodies), but am afraid that the ones I am willing to unload (the slower ones) won't fetch much money to make the sell-off worthwhile. For example, I would consider selling my FDn 20-35/3.5 L, but have noticed that the online market value for that zoom is not great. Ditto primes such as the FD 24/2.8 SSC and 135/2.5 SC. On the other hand, faster primes such as the 24/2, 35/2, 50/1.2, 85/1.2, and 135/2 are fetching premium prices, largely because they can be readily adapted to mirrorless bodies and mirrorless users seem to love speed. But they are precisely the lenses with which I'm least willing to part. So what's an over-burdened FD lover to do?
