Can anyone confirm whether the LED 50deg lens tube should accept the same retaining screw (the one opposite the focus knob) as all the other lens tubes (the 5/8ths one part no: HW5197) or does it need to be a longer one? I've tried replacing it but it's not biting.
The LED 50deg lens tube uses HW5508. Which is 7/8ths instead of 5/8ths according to our internal documents.
The Brass spacer on an LED 50deg lens tube is HW5507.
These parts are the same as used in XLDT lens tubes.
If you want both; a kit can be ordered using 7462K1017.
Thanks! 7/8ths might well be right... Was using an unlabelled ruler on a multi-tool!
