This lens hood is design to fit the Distagon C 50mm f4.0. It's not compatible with the newest CF series. The mounting is outside the cylinder of the lens and allows the use of filters.
This lens hood is 3d printed, there are some marks do to the 3d printing process. The material use is POLYLACTIDE, 3 time stronger then ABS but biodegradable, under some conditions. With normal use is really durable. Normally I paint this lens hood for a better protection and look. I'm always trying to improve my items, may be some little differences from what you see on the pictures.
The lens is not included.
For any question please contact me.
