Goerz Dogmar 180mm f4.5 image circle?

[koh303]

I am trying to find info about this Goerz lens.
Not much around except a google search which brought up that NYC Goerz Dogmars covered 50 degrees.

Can anyone shed any light on this lens?

It covers 4X5 for sure, but wondering if it is good for anything else...?

There are 4 Goerz catalogs (1913, 1915, 1940, 1951) on the cameraeccentric.com website, but unfortunately none of them list a 180mm Dogmar lens.

This one indeed reads 18cm F4.5....

In the 1915 catalog there is a dogmar 7" listed, but the price only. I am re reading that to see of any info on coverage.
The much later catalog lists 48 degrees at f4.5, so i guess it is 4X5 and no more...
Still a cool little lens.

Right. The catalogs on the cameraeccentric website are all "Goerz American Optical" whereas the 18cm lens shown in a closed ebay listing shows it on a German camera with the Deutsches Reichspatent (D.R.P.) marking. Guess you need the German catalog.

This lens is a berlin goerz (as noted in the first posting). I know there is a difference in Dagors, and so safe to ass ume that these are also different?

Click on this & it will take you to a few post discussing the Dogmar.http://www.largeformatphotography.in...archid=4036100

You are not going to find anything beyond the fact that the Dogmar is a Gaussian type w/ eight to air surfaces so will be low in contrast unless coated as you stated the design has a max 50 degree coverage and nothing beyond that. The lens may be used up to 5x7 but w/ little left for movements but a nice lens for 4x5.

It is often found in sunken mount in shorter FL as the where meant to be Goerzs "speed lens" & used on FP reflex cameras.

I have used a 165 dogmar on 5x7. I have an example somewhere on 5x7 film but can't find it, not shure bout infinity though. They may cover more than suggested. These are on fp100C. They have the most amazing colour rendition and I compared with a sironar s which was cooler and more muted. They are convertible and either the front or back elements an be used for 2 different longer focal lengths, but are very soft that way. Recently I put mine in the goer pile because I have sold some stuff but it seems to be happy here.

first is on 5x7, second is single element on 5x7
