Does the Hasselblad use Bay 60? If so, the cost of a B+W, Heliopan or Hoya filter is going to be very high -- probably more than $200.

I ordered a Bay 1 B+W infrared filter, and it took about four month to arrive. I think these are made in small batches, probably when enough orders have been received.

I'm planning to use it with some Efke infrared in 127 format and a Baby Rolleiflex.
