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 (https://www.ebay.de/itm/165979129220?_trkparms=amclksrc%3DITM%26aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D247416%26meid%3Db1feed6521f341389ee391afdcd7d6ad%26pid%3D101195%26rk%3D1%26rkt%3D12%26sd%3D394509434241%26itm%3D165979129220%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv11WebTrimmedV3MskuWithLambda85KnnRecallV1V4V6ItemNrtInQueryAndCassiniVisualRankerAndBertRecallCPCBlended%26brand%3DNikon&_trksid=p2047675.c101195.m1851&amdata=cksum%3A165979129220b1feed6521f341389ee391afdcd7d6ad%7Cenc%3AAQAHAAABYMzHrtmBs5dQ%252FHIG5%252BRfYnxi7NXGqhNmkIynG8%252FJUFU8mFH0LR4rYiCzTE7ooZG50CTrFa800zEyCYXzaLce6aP2sNHYQFVEwDm5p%252FLuk%252FSeZYJ4KDvPkFH59OJf3XeGeYKecqqQTdGEPj5LqiOXakWiqBosmYbRU6pNWhnznOxgvMokJO6bWJ0BV1ZvKVaC1GirAaFulBg44L2QqdS%252B0rUlKeg0yWMo1lSu6KnOgHPw65FtX945fAYtBxT8knykaHR2l8TODD8nU8Bj89KyBSNndcL7mfwdcnZyDUpBTgw8LEp9KxPpe9jZmKZS3N3UhImB2lczTXxTgTHJMQIqnxcOoAy%252BTBt3yE6QiF8rWzZdHgU0rb3%252Bg9p6XRr4kiEuX9G3%252Fr4N7r17INgZkRdlaIkRIIcJy0q96sIlV37Cy9xeXwd5wIIOLaCmIskRZWc2rO6JfPKIQtWF6ZlAZs%252BgbS4%253D%7Campid%3APL_CLK%7Cclp%3A2047675)

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.

[John Layton]

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

[Andrew O'Neill]

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.

[Drew Wiley]

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!:cool:

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?

[Melissen-Ghost]

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

The Nikon loupe comes with both the translucent and the opaque skirts.

A small magnifying glass already comes on one over-stuffed model of Swiss Army knife. Now we need out own version of Swiss Army knife, with a full-sized Peak 7X fold-out loupe, a filter wrench, a filter ring dent puller, a fold-up ladder for too high tripod extensions, etc; and yes, perhaps a built-in fire extinguisher too.

Yes, but with the reflex mirror usually protecting the shutter.

But will it still come with corkscrew?

[Drew Wiley]

Not just a corkscrew, but a long wood coring bit - just in case you need to check the age of a Bristlecone pine!

They'll sell a gazillion of 'em!

I caught my speed graphic shutter on fire accidentally leaving the focal plane shutter cocked. It's not a bad idea to keep a cap on the loupe if it's not stored in a pocket.
(to extinguish it, I remembered stop, drop, ROLL, and tripped the shutter to roll up and extinguish the fire) It smoked and stunk, but it was patchable.

[Drew Wiley]

Well, John, I don't advocate those boring attachments. I do know exactly which Bristlecone is now regarded as the oldest one ever found, and have photographed it several times. No, none of my prints will inform the viewer of that, or its location, amidst my other Bristlecone shots. The previous record holder once had a sign in front of it, and got vandalized - a particular well-known photographer took a saw to one of its limbs for sake of a fireplace mantle trophy.

That entire Methuselah incident was both a tragedy and a disgrace.

[Drew Wiley]

Well, the culprit in question had the nerve to brag about getting away with it to a backpacking pal of mine who lived right across the street from him back then, and saw the limb himself numerous times. But no sense going further. Let the dead rest in peace. I merely referenced the incident in relation to the wisdom of no longer drawing attention to the oldest trees, and tempting that kind of thing. They do still have a sign in front of the "Patriarch tree", the largest known bristlecone, but not the oldest. But the same individual was known for quite a few similar violations of known rules intended to protect fragile or irreplaceable natural wonders. Yet nothing has done more damage overall than posting GPS coordinates or maps online, and drawing herds to what were once tightly held local secrets.
