To loupe or not to loupe?

[Jim Noel]

If it was maybe all of the camera manufacturers of all formats would supply their cameras for aerial imaging today.

The only reason it is not the easiest is that the method of such viewing takes sustained practice. A task that too many are unwilling to undertake. I learned the procedure in the 1930's and continue to use it.

How well can you use an extinction light meter?

Tell us more, please!

I thought those were extinct?

[RLangham]

I've never really allowed myself the luxury of a real loupe. I started out using an orphaned 45mm lens from a long gone minolta slr. Moved from that to the viewing lens from a broken Ciro-flex (tlr) rigged into a short piece of tubing....I've settled on a pair of +3.25 reading glasses on a leash. I don't know if it shows in my prints...and I guess I don't really care.

I bet I use the same lens as my loupe! MC Rokkor X 45/2?

I had a lot of practice with them and became very efficient. I still have one in my closet along with several range finders, straight threaded cable releases and other
useful tools from the past.

Have you looked at this one from Edmund?

Does this loupe come with something i can hang it from my neck.

What is it's length? Are there different magnifications and focusing?

I just got a new 4x5 with GG and fresnel. Are there considerations with focusing due to the fresnel?

[Bernice Loui]

The optical grooves on any Fresnel lens affect the ability to use any magnifier. This and a long list of reasons is why any Fresnel "brightness" improver can work against the photographer.

Stopped using any fresnel decades ago for that long list of reasons. IMO, best is very fine grade ground glass precisely matched to the film holder's film location.

Have the Horseman versus of this 7x loupe, been using this same loupe on the GG for decades. It's quite beat up and well used now, still works fine and remains the preferred GG loupe to this day.

My favorite is the Peak/Horseman/Nikon 7x model, variously branded.
