WO FLAT 61 FOR Z61 - WHAT YOU NEED TO KNOW
The large end of the WO Flat 61 threads directly into the focusing tube of the WO Z61 scope. The other end has a non-standard 48 mm T-thread! You can’t use a standard T-adapter. This fact is not made clear in the information about the Flat 61. You must order the WO Nikon T-Mount 48mm thread or the Canon WO Star 71 M48mm in order to use the Flat 61.
