Ok I have been using an old 8x plastic loupe, it woks fairly well however I think it was designed to focus on the surface of an object.
I want to own a loupe that allows me to focus on the film plane (the inside of the Ground Glass) not the surface.
Anyways, I found an old Schneider 8X Lupe (isn't current manufacture) but it didn't come with any instructions. I was wondering if any of you guys have used or still use this loupe what are your thoughts?
It does extend
And retract
Here are a few questions, I would like to hear some input.
Is the ability to focus a loupe to the registering position where the film will be the most critical location of focus?
My thought is if I place my loupe on the smooth side of the glass, it is around 1.5mm farther away from the film, and thus out of focus (if ever so slightly)
I understand a how a diopter is to be a adjusted (to see the markings on the focus screen clearly or on a spot meter for example) I have also red lots of conflicting information about loupe's and just using 3.5x reading or magnifying glasses from the $ store.
Lastly I want to know more about exactly what my new 8x lupe is doing, as I said it came with no instructions, it is out of manufacture. The price tag was $200 bucks, I got it for penny's, ( a luck find) so you can imagine how excited I was to find it.
Does the Schneider 8X Lupe have the ability to adjust the focus to different depths? If it does, how do I know when I am at the proper depth? I turn the 8x lupe and get a sharper image on the GG but it also has a ton more of adjustment, I cant imagine an 3/4" to 1" of adjustment to focus on a ground glass or correct for bad eyes.
I tried to remove the lens board and point the GG at a flat white wall and adjust focus in the grain on the inside of the GG but not sure if this they way to do it.
I hope I dont sound a little dense. I am just looking for some clarification abut my specific loupe, ( a link to any instructions), conformation of proper registration of a loupe to a GG. Lastly, any thoughts on this loupe. Is it a good one or should I sell it and get the 3x readers.
I know Schneider is a maker of word class optics. However if this is in fact a great loupe why would they build those new silver plastic ones. This loupe is all metal with a nice red plastic lip that wont damage a GG. It really seems like a nice one. I just cant seem to find much info on it.
Thanks or your time in response, AKf
