Works very wellPros: Cons: Comments:
The only thing I wish this had was an inside flange to allow SLR lenses without manual mode iris to work properly. (The Iris set pin cannot be pushed in to set the iris F stop for auto only lenses).

This Baader adapter is perfect for anyone using M42 mount camera lensePros: Cons: Comments:
This is an M42 (Universal 35mm camera lens mount) to T2 adapter. It has a female M42 thread for the lens and a male T2 thread for the camera body. This item is a neccesity for anyone using 35mm M52 camera lenses for astro-photography. This item is made with Baader's usual excellent fit and finish. Since cameras and telescopes vary you will need to get the spacing correct, usually with a Baader T2 extension tube.
