    Loupe that stays adjusted

    I have a couple of loupes that adjust by screwing in and out of their cylindrical sleeve. Unfortunately, they drift, so pretty soon I find that they are out of adjustment and I cannot see the focus clearly. Are there any ground glass loupes that have a locking adjustment, say like the one on the Pentax spot meter eyepiece?

    Actually our eyes vary from day to day regarding focus, so locking in your loupe today doesn't mean it will be set correctly for your eyes two weeks from now. That said, I'm sure there a loupe out there that can be locked. I just don't own any.

    If you have an adjustable loupe that you like, you can add this inexpensive locking device that fits across the eyepiece ring and the barrel to keep it from drifting. It is also useful for many other equipment locking applications--

    I 'lock' my loupe using masking tape, about 1.5 full circle. I re-adjust and re-tape it maybe twice a year to match my eyesight. It does not look too bad if you do it carefuly.

    Put a dot of the non-locking loc-tite on the threads. That will make it adjustable, but only when you intend to adjust it.

    Man ain't that the truth. About 7 years ago, it was like someone flicked a light switch and all at once my eyes got old.

    Now, when I shoot, it's my regular glasses to choose the scene, then take the glasses off while I set up the camera. Reading glasses to compose the shot on the groundglass, take them off and use a loupe for fine focus, put the readers back on to see the darn meter and the settings on the shutter... When I use a lot of movements, there are generally several iterations between loupe and reading glasses, or no glasses.

    However, I firmly hold to the belief that getting old beats the alternative.

    I always just used tape, but your idea is great. Thanks, I will try it.

    A little Elmer's glue has gone a long way with my Peak loupes.
