I bought one from B&H Photo, it only came with instructions in Japanese. I don't want to just screw it on a lens and point it at the sun without understanding all the instructions. Does anyone have an English translation they could share?
Thanks

That pretty much is it. It is supposed to reduce light by 1/100,000 The instructions basically say
Don't point your lens at the sun without this filter.
Don't use the optical viewfinder.

So maybe liveview or infinity focus

comes in 58mm or 77mm sizes and you can use rings to adjust for your lens.

Set focus to infinity, aperture priority, position in live view. Bracket your exposures.

Are you sure this is enough attenuation for solar viewing?

I would send it back to B&H. Make sure what you are doing if you are going to shoot pictures of the sun. It can destroy everything from the lens back to you eyes.

I'd get back with B & H and tell them you want a manual in English. Sun filters are nothing to be screwing around with either for your camera or your eyes.

It won't bother the lens at all, which is after all transparent, but it can be a problem for something at the focal plane.

Not much more information regarding the filter.
Let us know how the shots come out

You are right, of course; the main damage will be at the focal plane and to the eye of any human viewing that image. But a few engineers in optical design and research have begun to advance a new theory. I suppose the problem never occurred earlier due to the relative simplicity and comparatively crude construction (yes, even Zeiss and Leitz). But today's search for perfection has raised us to a whole new level of concern.

Due to the complexity and construction imperfections of many of today's lenses, there can be several points at which the suns rays converge in a lens, even though the desired objective is to point the lens directly at the subject, thus focusing on the image plane. Those anomalies are capable of creating temporary instances of heat at random points within the lens, thus damaging portions of the lens. Merely bringing the lens onto the subject can create minor damage to a lens (minor in the fashion of the laser on Auric P. Goldfinger' table in Goldfinger, although much briefer and less devastating.)

No, it won't ruin the lens; any damage will, after all, be instantaneous and relatively minor (and, according to Canon engineers in reports published about the turn of the century) primarily at the edges of the elements, the bonding of said edges can be weakened, as can the bonding within groups of elements. Remember that the first two missions to service the Hubble telescope dealt, in part, with optical issues, including correction of a 1.3mm error in the mirror installation. I doubt that any human eye could detect any change to normal photographic lenses, although according to Canon (years ago) repeated exposure to such high intensity light can eventually become noticeable. I doubt that I will ever live to see that happen.

Please do not ask me to document any of the Canon information. It was published in books published by Canon for a number of years and was fascinating (and brutally honest) reading. Unfortunately, the hasty departure of my now ex resulted in a chaotic situation which resulted in the loss of my photography library, as well as thousands of slides and prints. I still cry to this day, especially when I recall the books and magazines from or about Leica.

Thanks for the information and link. With so many designations of filters running around, including arbitrary numbers, index factors, stops, etc., I am grateful to have a plain attenuation factor to use.

With this filter on your lens, your camera won't be hurt by pointing it at the sun - use Live View and manual mode, you'll be able to get decent images of the sun.

I shot this with this filter, manual mode, ISO 100, 1/1000 shutter, f/11.0 aperture.

Auto white balance resulted in a white disc, I prefer this, so I pushed the color temp up in Lightroom.
