Perhaps you can do the same with the Helios 40 to check if they share the same design.

They probably won't be distinguishable on a film, especially B&W Very Happy.

Thank you for the test!
This confirms that they share the same design.
Differences can only be marginal.

Definitively!

This makes the Cyclop a real bargain for the price you can get one for Very Happy

Now to figure out how to install an internal diaphragm.

Waterhouse stops in a slot? It worked for years before fancy diaphragms.

That might do it. I'll have to examine mine to see if there's a place where a slot can be machined - where there is a void without glass. I suppose near the rear since the focusing sleeve covers the front 2/3. The rear element is very easy to remove, so I'll take a look again. Good idea, thanks.

For what i can see, the bokeh in the Helios 40-2 looks more define than the Cyclops... look at photo 1 and 2.
