Split field filters are filters composed of two
halfs. One half is a close-up lens, the other half is empty. Both parts
of the lens can be in focus at the same time or you can leave one part
out of focus for a special effect. The Split field filter SF will let
you experiment with different combinations and obtain some very
interesting photos.
This Filter comes in a twist box for compact storage
The filter is branded "Regent", the brand that preceded "Kood". The filter comes from the same high quality Japanese factory that Kood get all their Japanese filters.
