Nice. I'll be interested in see the Telefogar too, especially at f/3.5. I've been curious if it offers anything unique.

If I ever find a Domiplan that has working blades I will probably pick it up. From fairly limited evidence, it appears to make background bubbles too in close up shots.

You need to shot wide open for the bubbles...

Yes it does, but so far my experience is that it isn't nearly as good as Trioplan. Just in case I have one of the many bad copies, I have purchased a second one to try. Following are Domiplan...

There you go - cheap bubbles. Domiplans seem to go for under £10 here. Maybe I should try taping one to my Nikon D600 and just use it for closeup. Is there really any good reason you would use this lens at infinity focus? And as Calvin says, why would you stop it down, so who needs a working aperture?

Both are good points. If you stop down or shoot at infinity (or anything not very close) you're essentially using it as a normal 50mm instead of special effect. As a normal 50mm it can be decent when stopped down to f/5.6, but no purpose if you already have better lenses. Surprisingly, the Trioplan I have is also a good, sharp general purpose 50mm, albeit a tad slow.

Mounting to a Nikon will definitely render it close focus, but I don't know how close - or I should say how far you can focus. I wouldn't want it restricted to just a couple of inches, but approaching 8-10 inches could be nice. I will be attempting to bring my second Trioplan down to that range, but ultimately it will wind up wherever I like it best after some tests. I suppose I can do the same with one of the two Domiplans I'll have.

I should mention that I have a hard time focusing the Domiplan precisely, even with the excellent focus aids in the NEX. It doesn't pop into a clear focus, but seems to go from blur to less blur, then back to more blur again without passing sharp.

Your price estimate looks correct. I paid about the same for each of mine - just over $15 including shipping. The second one, yet to arrive, looks mint.

Rain and cloudy day, almost desperate...

(resize and some contrast adjustment)
