Hello All,

I bought a cople of these lenses on Ebay, and it the image on the
easel seems quite sharp. However, one problem is that none of these
have have Click Stops.

Is this a feature of this lens? Are there other enlarger lenses also
(modern ones) that do not have click stops?

Can anyone provide some information on how one uses a lens without
click stops?

I am finding it very inconvinient to use this.

Finally, if this lens is supposed to have click stops, How can add one
(a small metal ball should fo the trick). How do I open the lens to
insert a metal ball?

Thanks for any help,
Sreenath
