desperate help needed

[dave42]

hi all,

 

i just purchased an early angulon 90.

 

the guy i purchased it says its not the standard 40.5 but could be a 30.5 or a 20.5 size.

 

the lens is in the mail and i wanted to use it on a trip this weekend.

 

does anyone know where i could get step up rings so that I can get to 40.5?

 

thanks in advance!!!!

Marc,

 

Beware! It seems to me unlikely that the filter standard could be as low as indicated. Are you sure that he is selling you a 90 mm Angulon and not a 65 mm Angulon? The latter lens was rather common in the old days, used in 6x9 Technikas as well as in 6x9 Graphics.

 

I hope this helps

Since it's unlikely you'd get a step up ring from B&H that fast (that's where I get all mine), you can just hold a filter over the lens during exposure, i've dont it and it works in a pinch. I even do it for 35mm and dslr in a pinch if i dont want to screw the thing on, usually either my 72mm polarizer or yellow-orange filters...

My 1939 90mm Angulon was 39mm, the 1951 model 40.5mm. I think. At least they were different...

It's probably 30.5. Although the Schneider website says a 90mm Angulon has a 40.5mm thread, there are nonstandard lens mounts that don't appear in their tables. I have a 1960-vintage 105mm Schneider Symmar that has a 30.5mm filter thread.

 

About 20 years ago I had a 30.5 - 40.5mm step ring machined by SRB in Luton, England. At that time I couldn't find a commercial source for a 30.5mm step ring.

 

Nowadays you can find 30.5mm step rings on the much-despised auction site for a few dollars. I think they're used for digital video cams or something. I have a 30.5 - 52mm ring that I still use on that Symmar.
