Not really. It is nicer to have an adjustable loupe for GG.
There is no difference (in usage) between neg/slide loupe and GG focusing loupe, right?
Remember, the image appears on the lens side (or back side), of the GG.
So, in reality, you need a loupe that has, or can adjust, a proper focus point
beyond the surface of your GG, equal to the thickness of your GG.
A loupe for the light table basically focuses on the surface of the table,
not through the table glass, like a GG loupe needs to.
With all of this in mind, I found that a pair of drug store cheaters,
(reading glasses +2.50 or so), work fairly well for me. For more critical focusing, I wouldn't
recommend common, non-adjustable loupes having more then about 4X-6X power.
I have found the lower powered loupes make it easier to see the
image 'snap' on the dull-grain, or back side of the GG.
For me, with higher powered loupes, all I seem to see is the grain of the grind on the GG.
Also, drug store cheaters worked better for me then 'linen tester' loupes that some may suggest.
Cheers Marc, that makes sense.
Many online sellers don't know if their item is for GG or film.
Safe to go with designated GG focussing loupe.
My favorite, and most used loupe is an old Calumet 4X power model.
The Calumet site doesn't seem to show a model exactly like the one I have anymore.
Calumet often contracts with other manufacturers, to either make items to Calumet
specification, or more commonly, just brand existing products with the Calumet name.
Someone mentioned earlier that some loupes have a sliding skirt.
These loupes are often said to be dual purpose; GG viewing and photo viewing.
When viewing photos, you raise the skirt so light will illuminate the photo.
You lower the skirt for GG and light table or slide viewing.
My loupe has the skirt, but I have it taped in the lowered position for use on the GG in the field.
I use a separate viewer at home for light table use that covers an entire 6 X 6 or 6 X 7 slide.
Below are links to images of loupes very similar to what I use on my LF, GG.
I found mine, used, for about $40 USD.
The Calumet branded loupes, new or used, are usually far cheaper then the big name
branded loupes, for basically the same identical model.
Yeah that's kinda what I want. Light and compact.
All I can see from the big auction site for 'designated GG loupe' is Toyo and other no-name loupes.
They look big. Not much smaller than Jupiter 9 I am currently using.
This Fuji looks good but the seller wasn't sure if I can use for GG focussing:
Also, I can see a Peak 10x with Scale. Not sure this one is okay or not either. 10x is a bit too much but then my Jupiter is about that ...
I find a drapers glass very useful.

i use a (toyo) monocular viewer
got it on ebay maybe 10 years ago
but you can use anything
i sometimes use a cheap peak loupe purchased for a few dollars
and other times i use a cell from a tessar lens
i am sure a cheap dollar store magnifier for $1 will work great.
just because something costs $$ doesn't mean it is good ...

Take the lens off, use as loupe. For added humor, stuff the dead camera body with potting soil and plant a seed of some sort in it. Makes a great conversation piece.
Another vote for old 50mm lenses.
