What is the orientation of the lens in my 36 degree XDLT lens tube?
Symptoms/Issue
Some lenses for 36 degree XDLT lens tubes used in June 2022 are missing the blue dot to denote lens type and aid in orientation.
Description/Explanation of Issue
This applies to the 36 degree lens tube only. If you look at the lens from the side, one side has more of a curve than the other. The flatter side faces towards the fixture side of the lens tube.
