I happened across a Schneider 180mm f/5.6 D-Claron covering 8x10. What exactly is it? I thought clarons were graphic arts lenses---I've heard of Gs and Rs but never before a D. Anybody know anything about these?

You've looked on the wrong Schneider site, I believe.

Thanks Ralph and Ole! It looks like it would be of marginal use for landscape work.

John, who sold it as covering 8x10? At infinity, that is.

Dan,
Photo Graphic Systems has this lens in their inventory. www.pgsys.com

Thanks for the reply, John. I note that the D-Claron is fixed aperture, also that many of his coverage claims are very optimistic.

Cheers,

Dan

Don't forget, there are also "C" clarons too. Who knows, maybe they did the whole alphabet at one time or another. :)

Seems to be several variants on the "claron" name and/or line, many used in commercial or industrial applications. Many of the ones I have seen are fixed aperture as has been pointed out before. This is the real issue with many of these claron lenses IMO. You can always use a lens without a shutter, but without an iris? The issue is these lenses, in order to be used in a shutter need to be taken apart and likely remounted in a new barrell, which I think would add greatly to the cost, so much so you might just be better off with something else.

Joe, its worse than that. I have a couple of fixed aperture lenses in barrel, none made by Schneider, that aren't made up of cells that can be unscrewed.

I would be wary of any claims made by that seller. I have had some experience that shows less than acceptable knowledge on his part. Your mileage may vary.
