Thanks Ray,Scott
It is very easy to change from the supplied 63MM (2.5 in lens to the 101MM lens If you look at the tube, it is threaded on both ends the 101 mm lens installs in the opposit end of the tube.
it is a long thread you just remove the 63mm and insert the 101mm in the other end of the tube,
make sure the flat side of the lens if facing the work, drop in the o ring and screw the retaining ring down to snug the lens.
If you have any more questions or would like a pic or two for clarification let me know
Ray
With the 2.5 (63mm) lens we use a 8mm spacer between the end of the tube and the material. Do you use a 46mm spacer with the 101 lens? (101mm - 63mm = 38mm + 8mm = 46)
