The Nikkor EL 50 has a 39mm lens mount (the filter ring is 40.5mm (1) ). The Schneider Componon S 50 is also 39mm lens mount (the filter ring is 43mm).
With the HQ camera, and a 16mm size target, is there a need to reverse mount? There may be different views, my guess is no need to. So the items below are for normal (not reversed) mounting.
- Starting the the lens mount 39mm male.
M39-M42 adapter ring - What is the spacing needed ? that will vary 16/8 and full film or only exposed image.
T42 is common, so I am buying to have flexibility set of extension tubes to be able to change/adjust as needed. (2) - Lastly, move from 42mm to CS mount (HQ removing the C to CS ring).
42mm to C-mount adapter will do. - Mount directly to the HQ sensor.
This thread has good examples of results with the Schneider, but for extension purposes the Nikkor EL 50mm is similar.
EDITS
- (1) Filter thread of the Nikkor EL that I have is 40.5mm, although some spec sheets indicate 39mm.
- (2) T42 is 0.75mm pitch. Other 42mm items are 1.0mm pitch. See posting below for sequence with adapters for thread pitch.
