I'm like Jes - it's a body cap for an Exakta.
Stir fried roo was one of my favourite dishes down under. Emu sausage was very memorable. Have to say Sydney and Melbourne (the only places I visited there) have world class cuisine.

Just like to add that the Domiplan is very prone to iris not stopping down effectively, often not stopping down at all. I checked out a repair information site, the man said it has not much to do with the iris mechanism itself, but is due to the stop-down linkage rockers not properly lubricated. In fact I have several examples suffering from that Sad

The Moleman is close enough, deep fried octopus and a favourite fast food amongst the local Vietnamese community. Gotta say I'm quite partial to them as well.
If the roo steak was tough then it was overcooked. Now if you eber want to chomp on a decent sized drumstick nothing beats emu. Gotta love our edible coat of arms.

That's a relief, I thought it might be insect grubs or baby croc tails. Smile My son cooked the roo steaks on his BBQ, I'll blame him then. The beer was nice though.

Patrick, I agree about the cuisine. For my wife's birthday treat we were taken to a fab modern restaurant across the quay from the Opera House. http://www.wildfiresydney.com/

Thanks for that Seele, I'll see if that will cure my lens.

Well, I just tried your suggestion Seele. I didn't have to go too far before realising it's definitely a problem with the blades sticking on my copy, so lubricating the mechanism didn't help a lot. Anyway, for anyone else who wants to try, here's how.

The aperture actuating mechanism is revealed by unscrewing a cover trim ring at the rear of the lens:


The pin pushes down on a half-circle rocker mechanism pivoted on a screw at each end. The rocker on my copy was obviously being compressed by the screws and seemed a little stiff. A tiny drop of oil on each screw helped. I didn't go as far as removing the rocker.


If anyone wants to know how to jam the auto mechanism to use the lens in stop-down mode, it's very simple to wedge to rocker down with a piece of a match or toothpick etc.

Thanks a lot for the clue, Peter!!

Thanks, Peter. My Domi now has a piece of folded paper inserted there. The blades are a bit lazy but have freed up a lot with being worked back and forth.

This is the webpage I looked at, on repairing the Domiplan; although hosted in Taiwan in the Chinese language I guess you can get the drift of it anyway Very Happy

Sven , how did you manage to "jam the iris actuator " ? I took a Domiplan apart and modifying the diaph mechanism appears to be not obvious ...
Very Happy


In the same way as Peterqd describes in the last of his pics. but with a folded piece of paper instead so the ring could be mounted back.
It still works today so maybe it can remain a permanent soloution.

Surprisingly good quality (some nice photos as well). I guess that they were not taken wide open.
People seem to get rather varying results with this lens.
Smile

I noticed on mine that the rear lens package was not firmly attached. The attachement is rather flimsy with 3 small grub screws.
I think the quality improved a bit after I tightend the screws.

Dave your copy is show great IQ I like it pretty much.


PostPosted: Thu Sep 03, 2009 7:32 pm    Post subject: Reply with quote
All of these were taken at f:8, 11 and 16, where I would normally have used this anyway. In the fullsize pics I can see where the IQ is starting to deteriorate at the edges so on a FF cam, this wouldn't be very good at the outer quarters.
All the pics have a normal tickle of levels and slight USM, to even things up between this and others. Pics were all shot in raw.

Sven , many thanks . I'd just made the modification and replaced the piece of paper with an adjusted spring coil (3 turns) , 5mm diameter (0,02")
It works very efficiently , and it is very simple to install. Very Happy

Wide open, special against light, Dimoplan 2.8/50 brings a lot of shame to German optics. This is example of the lens which can be used in some situation only. All samples were only cropped, the first one shows white spot in place where lake is visible. Domiplan could be quite sharp in the center even wide open but corners are awful and bokeh is a mess.
