Artar, Artar, barrel and shutter question for Ole

[Curt]

I have a very clean RD Artar f9.5 10 3/4" in a complete barrel with working aperture and filter door. I also have a RD Artar f9.0 9 1/2" very clear and clean in a barrel with an aperture that has no lever or markings and missing the filter door.

I have the 10 3/4" front mounted in an Alphax Shutter, the heavy stainless steel one, a Synchro model with no preview so I have to use "T".

I was looking at them and realized that the elements of both lenses were the same thread. Now I have two lenses that can either share the same barrel and or the same barrel and shutter. Essentially a complete front mounted lens and two elements of the same mount size.

What would you do with this combination of lenses, shutter and barrels?

Thanks,
Curt

To be honest I have no idea what I would do!

Probably put the one I like best in the barrel and shutter, and put the other one in a drawer for later - and forget all about it.

Now where did I put those Xenar cells I took off the Compound #3 to put my 355 G-Claron in the shutter - and where's the barrel from the G-Claron? Could they be together?

If i had those two RD's in pretty close focal lenght i would sell the one with the least use and get the other one mounted in a shutter. The money would not suffice but would get some of the job paid off.

Ole, i can't believe you replaced Xenar cells with G-Clarons

...Ole, i can't believe you replaced Xenar cells with G-Clarons ...

Since I had one 210/6.1, one good 210/4.5 and one crappy 210/4.5 Xenars, I figured I needed one Compound #3 more for the 355 G-Claron than for one of the 4.5 Xenars. At least for when I don't want to carry the 360/5.6 Symmar around - and I couldn't very well swap out the 210/6.8 Angulon!

 

[JLP]

Makes sense. Forgot you have more Xenars than most have film
And perhaps even an extra flange.
Sorry, this is an Artar thread.

I am confused. Doesn't the difference in focal length preclude the sharing of the barrel in either case? It would seem the internal separation should be different.

Not necessarily. Many lenses were designed to screw directly into a given shutter, even if sold in barrel, so they could be used either way. I have a 210 f6.8 Graphic Raptar that is a direct fit into an Alphax shutter. I also have a 159mm f12.5 Wollensak Extreme Wide-Angle that fits the same shutter. I can interchange them if I want, other than the aperture scales being really off if I transpose the lenses.

I understand that. I have a 160mm Raptar that screws into a Alphax shutter. I understood that this was switching barrels around with two different lens element sets. That's what confuses me.
It reads like he has a barrel set and a barrel modified for use in shutter, he just wants to change the lens elements. That might not be possible if the focal lengthes are different. The internal spacing requirements might be (and quite paossibly are) different for the two sets of glass.

If not, the answer is simple. When you want to use it in barrel use it in barrel. When you want to use it in shutter, do so. A casket set, no?

Goerz did that sometimes. I have an 8 1/4 Dagor in Ilex 3 and discovered that a Goerz Robertson 12" Artar was identical size and threads. Makes a neat little 210 / 300 and aperture is one stop different. I recall the 16.5, 19, and 24 inch Artar are same barrel / thread? I just wish some of them were direct fit to shutters without adapter barrels.

The two lenses are in their own barrels which are the same dimensions. I have the 10 3/4" in a barrel mount and front mounted to the shutter. The elements are threaded the same. The barrel aperture stops down to f90 and I'm still thinking about what I will use them for. It appears, from the Goerz chart, they have some nice coverage.
