Fire by Loupe?

[Melissen-Ghost]

Hello everybody,

maybe it is a stupid question but Im new in the LF world and Im looking for a 4x Loupe which I can carry around my neck when Im out in the field.

Is it necessary to have a protection cap on the upper und lower end of the loupe so that the sun will not burn a hole into your clothes?

It is just a thought but it was one of the first things that came to mind.

By the way: Are there any No-Gos for a loupe when it comes to get critical focus on the ground glass? (scratching the GG is one I guess)

I had one in mind from Nikon! -> LINK

Would there be anything that speaks against this loupe?

Thanks in advance!

Ha! I guess if you're not moving at all, and just sitting there with the bright sun facing you. I've never heard of an incident. But I have known of numerous forest fires caused by a glass bottle laying in the grass. I don't typically have my own loupe out for long periods of time because I want it protected when not in actual use, just like any other lens. And focus loupes are typically longish opaque barrel things, and not like a simple flat meniscus magnifying glass - so are not ideal for some Boy Scout trick trying to start a fire without matches.

bigger problem is folks burning holes through their rangefinder Leica shutters - by leaving leaving their lens caps off! Happens!

Funny, I never really thought of that... I'm think I'm safe though, as it's usually in a breast pocket, with strap around my neck.

If you ALWAYS leave the cap on your rangefinder lens, you'll never need to worry about the sun, because every shot will be a night shot! I accidentally got a couple of those "night shots" with my Fuji 6X9 this past winter. It's easy to do with a rangefinder.

Fire by loupe?
How cool is that?
Got to love multi-tasking gear!

The Nikon loupe you linked to is missing the opaque skirt needed for focusing on the groundglass. Carry the loupe in your breast pocket.

That I knew . Well it would also fit for Pentax 67 users, since the Pentax also has a cloth shutter, right?

Thanks! I almost thought so. I guess the Nikon is also available with the opaque skirt.
