Great set of five primes. The lenses were purposed for 35mm film cine
camera KSK. This camera was used for animation and combine shots, so it
has focal-plane shutter. That is why rear part of the lenses looks like
long cylinder.
It will be difficult (if possible at all) to adapt it to a reflex
camera, but with mirrorless (hybrid) DSLR you have better chances. You
may just remove optical blocks from focusing mount and use your own
focusing system.
Very used condition. There are no other problems that few cleaning marks and some dust. Low price.
