I tend to use my mirror for non-traditional mirror subjects. I like it when used, like here, where the OOF areas are darker and there are no donuts.

That appears to be much older than mine. Mine is the Rubinar 1000/10 made in 1998. It has some different features.

The Rubinar 1000, at least, came out of Leningrad No. 3, a factory making lenses for KGB, where the priority was to get them good. The now commercial maker got the IP of the design for a song in the sell off of state assets.
My impression of the mirror lens talk in the early 80s was that they were designed to be smaller and cheaper than standard lenses of the same FL, with emphasis on cheaper, so people of ordinary wealth could get into long lenses.

Also the viewing device on the Q shows the 'croped' bit as the full frame, making get good focus easier than when it is a fragment of the frame.

I think actually getting focus right. The focus action is very heavy, at least compared with Takumars. And also getting no movement.

I have the 1000/10. Your pictures are of a quality like I typically get but I have had a few that have worked out much sharper. There is probably more capability in your 500 than what you got.

The answer depends on what you want to do. In the old days there was a market for lenses out to 2000mm, very rare though they were.

Would one of the cheap K to M42 adapters that prevents infinity focus give enough extension?

If you have a use for a 1000 it would be a keeper, worth persevering with for a solution. Since you have it and the body it would pay to work out the minimum length you need to get it to fit. The M42 mount on the lens fits freely inside the K mount so you can se how much length is needed. Since the M42 mount is a simple metric thread it is reasonably easy to turn a piece of tube with a M F pair of M42 threads separated by probably 4 to 6 mm, being all the additional length needs to solve your problem. That would probably not lose too much long focus. If you can focus out to about 1000 yards it would be enough for wildlife but not good enough for aircraft or ships at sea.
The manual rates it as good for -10C to 40C. I have found scintillating is a real problem above about 25C.

Cross threading would permanently diminish the value of the lens and if done wrongly might also make a mount not quite perpendicular to the lens axis.
A really short M42-M42 tube might be the deal. Could you find someone who could turn one up?
I am biased against modifying the core assets of the camera and the lens.
I will tell the man who gave it to me about these variations.
The Rubina was made for serious professional use so IQ is excellent. Best that could be done at the time at any price.

They are different.
The mount end of mine in the picture I posted is the lens. None of those pieces comes off, and it focuses to infinity.
All the writing on mine, including the manual, is in Russian. That made it hard to read, only knowing English and ancient Greek - which was the key. Mine was certified on 24/09/00 (handwritten in the manual). My manual is written for two versions: MC Rubinar-K 10/1000 macro AND MC Rubinar 10/1000 macro. Page 4 says the Rubinar version has M42x1 mount and the K has a bayonet mount named "oprava". Anyone have any clues as to what that is? Was there a Russian brand using the Pentax K mount?
Also the tripod mount ring on mine is different.
I would suspect that there may have been changes in the lens from the early official use version to the now commercial version which can be manufactured and sold surprisingly cheaply for the quality because the IP was almost given away in the commercialisation of former state factories.

Paul, I dug mine out of the drawer and attach pictures here.
The first shows the mount end. There is quite a bit of space which clears the prism/flash housing on K100DS and K3 by a quite safe margin.
Second shows the front view with the filters and cap.
Third, side view side showing the Makro label and the MFD distance numbers and the serial number.
The fourth shows the front element which was concave facing out. This was done to manage the light reflection from the lens making it less likely that the lens would be spotted when in use.
Do these features look like yours?
BTW: does yours have a rather heavy focusing action, not like the old Takumars or M series lenses, which were so light that they could be moved by finger tip action, but firm enough to be secure when not touched? I find mine is heavy but does not feel wrong, just that they made it heavy.

How much does it foul the flash housing?
I tried using the lens on bellows and it did not make much difference to MFD which is 4m on mine which boasts macro.
But what you say about the filters suggests there is more than one version. Mine definitely has filters that look like plumbing fittings.

I was given mine with three filters (for others these are 116mm and go on the front), a soft black bag and a booklet in Russian (with poor quality printing, especially the pictures that looked like old style photocopier photos). No lens hood at all. If the hood is kind of normal shaped it is probably not special. It was too assist detection avoidance when using it for spy purposes. Two of my filters were originally stuck together (thread quality issues) and I got strap wrenches to separate them. It was hard getting one long enough to go around.

At least two in country now. Mine fitted on K100DS and K3. K3 had more clearance to the lumpy bit in front of the prism.
Focusing is tough. The focusing screens in both K100 and K3 are very poor compared with the MX for manual focus. The focus ring has very heavy action.
Do you have any pictures of the radar signature minimising lens hood that were shipped with them for KGB use?
To mount - place the lens vertical, mount facing up. Then gently turn the camera body to screw it on. When carrying I always carry by the lens with the body hanging on the back - never by the body. I am a bit concerned about stress on the mount with a 2.5kg lens.

There are a few long mirrors which are labeled macro, or makpo in Cyrillic script. I have not worked out the magnification of a 1000 with 4m MFD.

Is the heavy vignetting in the original or in the reproduction from the slide?

Good to see images from the different lenses together. Your mirror shows up very well. I agree about the way people look when they see large kit - probably because these days there is too much media about weirdos, and also the ease of distributing images electronically.

Interesting. That is consistent with my observation of the Rubinar 1000/10. I have an image of a seagull I put up a few years ago several pages back.

My impression of Russian mirrors is that they are good. I think they are because they were trying to make serious professional use lenses which are now on the public market

Interesting. I had contemplated whether it was possible - obviously.
The K series slightly pre-dated my first Pentax, an MX, in 1981 and by then, to my recall it had dropped from the catalog. I recall a 1000 and a 2000 in the catalog. But as an impecunious student in those days that was something to know about not to know.

A mirror zoom. I never heard of that before?

Depends on what length you reallly want.
I would recommend Rubinar 1000/10 and they also made a shorter one, I forget whether it is 500 or 800.
The Rubinars come from one of the leading Russian factories famous for making spy gear. The quality is very superior.
