compound #4 analouge

[Hollis]

I was wondering if there were any other shutters out there that matched the dimensions of the compound #4. I noticed the alphax #4 is damn close but maybe not exactly correct. I am trying to mount a zeiss tessar 165 2.7 and am having one hell of a time finding a compound #4 to use.

Let me know.

The Compound IV was made with at least 3 different tubes. So the Compound V/10 for the Symmar 360 differs from Compound IV/9 in front- and back-lens-thread and total lenght.

a symmar 5.6/360
The 5.6/360 Symmar was also mounted on a Compur 5FS with suitable reducing rings.

i need the compound IV/9 i believe with the 62mm thread. There was a symmar that had one of those shutters that I was out bid on the other day, not cool.

The dimensions for the various Compound shutters are in the post linked to in my signature. That doesn't tell you which version you need, though...

American shutters are US thread and Compound is metric. No interchangeability unless you own a lathe and have some skills.

Well, clears that one issue up. I shot the lens today with the ol stack a bunch of ND and wave a darkslide in front of the lens method and damn, swirly, swirly. Im glad I bought the lens and really want to find a shutter for it now.

According to the 1929 Zeiss catalog at cameraeccentric.com, the following lenses have the same tube as a 16.5cm f/2.7 Tessar from that year.

36cm f/6.3 Tessar
30cm f/6.3 Tessar
25cm f/4.5 Tessar
21cm f/3.5 Tessar
21cm f/3.5 Triotar

Double Protar (total, rear, front cell)
11in/16in/23in f/7.7
12.25in/19in/23in f/7
13.5in/23in/23in f/6.3

These would be a good place to start. I would compare measurements before buying in case Zeiss decided to change barrel sizes over the years.

The Compound threads aren't exactly "metric"...

29 1/13 thread per inch is the official thread pitch, given in the Compur-Werke repair manual. It's a result of an uncommon thread angle, later replaced by "proper" metric threads.
