A little electrical tape will also work well.

... you can add this inexpensive locking device that fits across the eyepiece ring and the barrel to keep it from drifting. ...

I 'lock' my loupe using masking tape, about 1.5 full circle. ....

All this makes me wonder - would an adhesive tape do..???

Ok, I have one of the Calumet/Horseman 7X loups that can be adjusted. But how does this work? Do I first focus with my glasses on, then take them of and adjust until the image is once again sharp? I have never used the adjustment but would like to.

With or without your glasses first focus the picture on the gg. Then put the lupe on it and focus the lupe so that you get the maximum sharpness of the given picture. Then you can again refocus the picture on the gg with the camera focusing knob. Sorry if I misunderstood your question.

Eric, I find it best to adjust the loupe with a slide on a light box. By using progressive eye glasses, you can keep the glasses on while focusing with or without the loupe. Problem is some people are not comfortable with progressive eye glasses because of their narrower viewing agle. If you are not using those, give them a try. I tried once and can never be without it.

Focusing a loupe for a slide on a light box and for use on gg are, of course, two different actions even if of the same kind. If you focus the loupe for a slide, it won't be focused for use on your gg. The gg surface you focus on is more distant than the film surface of a slide because of the glass thickness separating it from the loupe.

Thanks for the help everyone.

I am off to go photographing for a few hours and will try to get it adjusted.

GPS, You are exactly right.
