Raynox DCR 150 and 250 lenses
These are sold to be used as close focus adapters placed in front of
a regular camera lens, perhaps a point and shoot camera.
This page will not discuss that at all.
Extreme macro photographers have found that these lenses make excellent
"relay lenses" to allow the use of infinite conjugate microscope lenses.
These have become quite powerful and many articles can be found by searching online.
Both of these have a 49mm female filter thread in the front and a 43mm male thread in the rear.
The 150 has a focal length of 208.33mm, and the 250 has a focal length of 125mm.
