information about Kilfitt lens

Is there any more information about the Kilfitt-Makro-Kilar, 90mm lens made for the Hasselblad?

Jaco van Lith (Netherlands)

This lens is meant for the 1600F/1000F cameras.
It is significantly bettter than the Tessar lens often found with these bodies.
The Kilfitt Makro lens uses 41 mm inlay filters and has a MOD of 0.30 m
Filters are fitted by unscrewing the inner antireflection part at the fromt of the lens.
I have a copy of the sales brochure if it helps you.
