hi all,
i got this in a package purchase. i have never seen one before. it is a 300mm lens (rear element only) H 5,8. the disks are added to the front in a diffusion style soft filter set up.

there are 3 disks. H5.8-7.7. a 7.7-9.5. and 9.5-11.5. they all open and close the diffusion holes by turning the ring on the disks. it is in a compound shutter.

anyone got any extra info on this lens? what is the value?

i plan to shoot it this week.

thanks.

eddie
