cone type BD thread objective to M42 (42mm x 1) adapter (add about 50mm length)


 

This M26 x 36tpi mount is sometimes industry wide referred to as a "BD thread".

Is shared with Nikon, Mitutoyo and Olympus BD objectives. BUT Zeiss BD objectives take a different thread.



 

custom-made adapter (made of aluminum, anodized black) to use BD (M26X 36tpi) thread objectives

you can use another M42 adapter to mount to any digital SLR cameras (Ex: m42-EOS/NIKON/PK/OLYMPUS 4/3/SONY etc.), I have them all listed in my ebay store.



note for the BD thread:

"All Nikon BD (Brightfield/Darkfield) objectives always have the
M26x36 TPI mount. This is true of the old CF (210mm tube, 45mm parfocal) objectives for scopes like my old Optiphot 66,
This M26 x 36tpi mount is sometimes referred to industry wide as a "BD thread". Is shared with Mitutoyo and Olympus BD objectives."

Sorry,  it seems Nikon BD objectives have instead 0.75mm pitch, and don't generally fit in entirely





for the adapter only, objectives for demo purpose, not included
