filter and lens hood size

[mark king]

I have bought a 50mm f4 Distagon w/a lens for my Hasselblad 500 c/m and would like to buy filters and a lens hood. Can anyone help me on the sizes? Thanks

Is it the newest CF/CFi ?
Then the opening size is 070 and you can fit all bayonet 070 filters or 060 filters and screw ones with the appropriate adapters (Hasselblad 060 to 070 adapter code 3040775). Hasselblad makes UV, Polarization and the Softar filters but you can get other kinds from other manufacturers. The lens hood is called 070/CFi 50 and has a code of 3040771.
