Attach Camera Lens to an Eyepiece

A: Yes, some SLR lenses can be attached with an appropriate step-up ring (adapter).

The eyepiece ring (top of the eyecup) on XW Series eyepieces (and on the XF Series Zoom eyepiece) is removable in order to expose a 43mm - (0.75mm pitch) thread on the eyepiece barrel.

This thread allows an appropriate step-up ring to be attached to the eyepiece in order to couple an SLR camera lens to it.

Although PENTAX does not produce step-up rings, we may suggest looking online for aftermarket sources. It is also important to note that step up rings may not be available in all sizes.
