All of these lenses have been tested and used, (primarily for shooting video) and all are completely functional and in-fact pretty damn good. 35-105 FDn zoom is the last one left. I still have the Ciecio7 adapter too. Canon 35-105 f3.5 FDn, excellent minus condition: $80 plus shipping. Ciecio 7 Canon FD to m43 adapter, mint condition: $65 plus shipping.
