72.2mm enlarging lens--what format does it cover?

[chip j]

I have a brand new Axinon in that length (very expensive in it's day--40 yrs ago). I also have a brand new 45mm Axinon for 35mm. I'm hoping the 72.2 will do 6 X 6. Yes? No?

You'll find out when you try it.

It will do 6x6 quite handily.

Lenses vary in their design but usually one considers that if the focal length is greater than the diagonal of the negative then you should get good coverage. Usually 80 mm lens are used with 6x6 negatives so you will have to see what your lens does. You really don't want to push things as there will be light falloff in the corners.

Axinon? Never heard of it. What country is it suppose to be from?

Made by Freidrich in Munchen, Germany. The 45mm 4.5 cost $247 40 yrs ago. Tiny jewels!

That is certainly a high end price, probably for the commercial market.

lenses that price that long ago may have been process lenses designed for 1:1 or 1:2 enlargements but I'd be guessing about that.

The Axinons have an angle of view of 50-60°.

My 45mm has click-stops. I used an older one w/o them on my Durst enlarger & it worked fine. TIP: I think there's still a new 45 available on ebay for the price I paid---$25 + $5 ship!!!! (I bought 2 of them). Brand new!!! It's 25mm mount, but use a plastic adapter--a metal one is too snug.

How many lens elements does it have?

 

[AgX]

4E / 3G Tessar-type

usually only good for small magnifications I suspect, maybe 2X to 6X if you're lucky. 6/7 element lenses are usually much better.

I print 6" x 9" and the 45mm worked well for me.
