I have read that it's the best tele that Meyer has ever done.

I am still eating my hands because I lost one that I could buy for as little as 10 euros or something. I got sleepy on the couch and lost the auction end.

I have got a Meyer Trioplan 2.8/100 which is quite similar and a really good lens!

I really liked the pictures I saw from your Trioplan, Carsten, but I think that the two lenses are very different. The trioplan is a triplet glass scheme such as the Zeiss Triotar. The Orestor is a different lens scheme as far as I know.
The triplet lenses are great for "old fashion" portrait photography.

You're of course right, Orio!

I just meant the lens performance. Either lens is said to be a great lens!
(No matter which construction is used.)

Sorry that I did not state that clearly enough.

Yes Meyer has its best reputation for the medium tele lenses.

I know four different M42 versions of that lens, three of them are Meyer Orestors:
two zebras and one version looking alike the Pentacon Auto 135mm. The latest version is labeled as Pentacon 100/2.8, mine even as eletric version.. The later ones suffer from coating and aperture problems and the handling isn't very nice since you have to use a stop-down button in order to close the aperture, even if your M42 adapter pushes down the aperture lever. The later versions have only six aperture blades, the one zebra version I own about 16 if I count it well. The zebras are tiny lenses, the diameter is much less than at the Oreston 50/1.8, length about the same. Optically the 100mm's are almost equal, better contrast than a 135mm Orestor, and sharp wide open with some CA. The later versions you can get for about 10-15 Euro if you are lucky, the zebras are much more expensive, between 25-50 Euro.

There is not a lot of information in the web but I found some user opinions at the usenet saying the orestor is superior to the Trioplan.

Two pictures of the Pentacon 100/2.8 electric wide open:

One important thing I forgot to mention:

the title of this thread is a little confusing,
the 100mm Meyer lens I'm talking about is named Orestor.

Orestegors are the 200mm, 300mm and 500mm lenses of Meyer Optik as far as I know.

That is right, Martin.

The 100mm and 135mm lenses are called "Orestor".
Orestegors are the longer ones.

What the meaning of Orestor and Orestegor ?


PostPosted: Sun Mar 25, 2007 6:13 pm    Post subject: Reply with quote
AFAIK there is no "real" meaning, Attila!
It is just the name of the lenses. There might be a code, though, as with the Leica lenses.

I read once about the difference of the names, but can not recall now.

Perhaps I couldn't follow you, you can find explanation by Carsten on the first page.

Hi you all m42 freaks!

I am into lenses self repair too and i think i didn't put last element in Orestor correctly. I think it's performance is not optimal. I don't want to assamble-dissasamble multiple times to test. Please can someone provide a scheme - design diagram of Orestor? I would be very thankfull.

By the way (and as an advice to anyone trying the same): me fool was traing to clean it and was unscrewing the bottom screws. THen automatically proceeded to next screws and guess what: all aparture leaves just popped out of the lens! When i finished crying i try to put myself together and that day God was on my side helping me getting them back - i didn't even make mistake in proper orientation or else.

I am comparing photo results with FUJINON 100mm m42.

You're in luck as I'm working on one with sticky blades at the moment.

I'm hazarding a guess that you can't quite achieve infinity focus?

If so, you've fitted the rear element the wrong way round - you won't need to strip the lens to correct this as long as you've ensured that all the other removable elements are seated properly and tightened down.

Just unscrew the ring that secures the rear element and carefully pop the element straight out making sure it doesn't flip over.

Now flip it over, refit it and see if that works - bet it does. Wink

The only elements you can fit wrong in the Orestor 100 are the front and rear and it would be obvious if the front was wrong.

Hallo,

this is from the later 135mm Orestor, it should be the same.

Thank you Bob and Indigo (the scheme should but it's not the same:).

so it surely can't be any other element then last? Then i am very glad - i was also suspecting others.


It's unlikely since the other element in the rear pair is bonded into the removeable rear barrel and the centre group are bonded together thus making it impossible to refit these wrongly. Like I said, I think you'd notice if the front element was the wrong way round but less so with the rear.

I stripped an Orestor 2.8/135 and refitted the rear element the wrong way round and discovered that I couldn't quite get infinity focus - this is why I suggested you recheck the rear on your Orestor 100 assuming that all elements are correctly seated.

If you're definitely certain that all the elements/centre group are indeed correctly seated, try flipping the rear element - it's worth a shot.

My Orestor is currently completely disassembled including the blades. Laughing

My copy of this lens has the pentacon brand , and it is the electric version . 5 elements , same scheme than the 135 , that's ok . No so hard to dismantle and remount ... Beware of the last rear element , it is not exactly symmetrical ... This was my preferred 90/100 mm until I bought a smc-takumar 2,8/105 ... . I let this excellent "orestor" several years in the show case, and it became sticky ... I have no scanned pics on my pc , unfortunately , I can only say this lens gave me the same global rendition than the 135mm .
This lens is becoming very scarce , and the global production figure was perhaps 5% of the 135 mm one. However , if you don't want to keep it , i'll even pay the P&P ... Mr. Green Very Happy
