What is this Gossen meter accessory and how to use it?

[wallacjm]

I have several cameras that I inherited from my uncle:

• Yashica 120
• Mamiya 120 Professional f
• Canon AE1
• Canon EOS 620
• Canon EOS 650

They came with accessories: different lens, extension rings, lens filters, flashes, and more. I don't know what accessory goes with what camera or how to use them.

I attached a YouTube video on it. It looks like a view finder, Gossen made in Germany.

It is a variable angle attachment that can be used with a number of Gossen hand meters.
From the Gossen meter attachment brochure:

FWIW, it is usually a lot better to include a still photo in a post that asks questions like this - I tried to screen grab one from your YouTube video, but you didn't hold it still for long enough to make it easy!
In my experience, those attachments are most useful for metering stationary subjects where picking a small portion of the subject to take a reading off is important for accuracy, but a spot meter is not available.

I've tweaked your thread title as well.

Thank you! I don't have the meter for it. I did find it on youtube, but the person who made the video didn't know what it was for either.

Attachment to Gossen Profisix I guess.

It will fit various versions of the Luna-pro / Profisix meters including the SBC models. It lets you constrain the measuring area. Not as much as a true spot meter though.

Yeah, idea was to allow meter to work something like a spot meter. Had one on the past (like 20 years ago) and don't remember it being that useful (since it made the Luna Pro awkward to use) . Bought a Pentax spotmeter at the time and it worked much better so eventually attachment end up on the bay.

I still use this attachment when the resolution of a true 1-degree spot meter isn’t necessary, which is often the case. The only downside for me is then I forget to factor in the metering offset, or factor it incorrectly.

I had the Gossen Luna Pro SBC with a 5 degree field of view attachment, but as @bdial states it was not a true spot meter. So I sold it and bought a Pentax Digital Spot Meter which still gets a lot of use.

The advantage of this, besides the reduced angle of measurement, is it makes it a bit easier to confirm exactly what you are taking the reading from. Essentially it has its own viewfinder.
