Goerz Dagor Coverage Chart

[c_p_goerz]

Before I forget since I am uploading spec sheets here is the one for

Dagors, again I'll leave it up for a few months for you to copy. It

came from a 1914 catalogue and ranges all the way up to the

legendary(but never actually seen...yet) 35" Dagor.<P>

Has anyone actually heard of the 35" Dagor out there? I once heard

that a 100" version was made for one the worlds Fairs but it was a

vague rumour at the most.<P>

CP...Was there ever any difference in "coverage" or "angle of view" between the gold rim versions and the regular Dagors?

Thanks...Larry

I have a 12" Dagor with a serial number starting with 33. I figure it was manufactured somewhere between 1918 & 1927. I don't know by whom or where though. It is old & uncoated, but it is my very favorite lens by far. I use it on 8x10 & have never run out of coverage. Mine is in an Ilex #5. Someday when I decide I need another lens, the Dagor 16.5 or 19 is what I want.

 

Thanks for the chart.

Andrew, I had to print multiple copies because I have this problem of the darn thing getting spoiled by drool.

Hey L,

 

 

I haven't seen any difference in coverage between goldens and regular Dagors, you will see a difference between the even older Berlin Dagors and the series III and gold versions though. Even contrast is a close match with an edge given to the gold versions but thats because they had later coating while many older Dagors have none at all. There are only four surfaces for light to splash around in so even an older Dagor will perform well.

 

 

When you see those prices up there and translate them back through inflation those guys back then were paying a fortune for their glass!

I made the little exercise Andrew suggested: the inflation calculator on the consumer price index web site (http://www.bls.gov/cpi/home.htm) gives a factor of 19.09 between 1914 and 2004. So in todays money, an 8 1/4 Dagor in Compound would be $1,500. Since we are comparing list prices, that is not so different from a modern 210mmm.

Alright, that 35" one would be $20,500 in todays money.... ;-)
