Lately I've got my hand on this lens at last...
I have Trioplan 100/2.8 silver, non-V version, number 28009888.
Right now I have extremely dull gray weather so I can only shoot something inside my home. And I am surprised with TOTAL lack of sharpness. Wide open shots give that bubbles in bokeh, but in-focus things are completely blurred. Is this normal for this lens or I was "lucky" enough to get a defective version?
Please, if you own this lens, can you give me a sample pictures of something dull, shot wide open? Something like a cup on your table... I want to compare sharpness with what mine lens gives to me.
Thanks in advance! |

My Trioplan and Diaplan are sharp enough - on Canon EOS 5D.
It is not a very sharp lens, not recommended wideopen for reprographic like work
On a camera with smaller sensor, or without using the full field of the camera (croping) one loose sharpness.

Trioplan 100/2.8 is my least sharp lens along with Telemegor 150/5.5 (not 180/5.5!) and Tele-Tessar 250/6.3, maybe a bit sharper than the other two mentioned, but still bad. Also very soft.
Good thing on Trioplan sharpness is you can always compare your results with other users' experince as the lens is common, popular and often tested this way. But for Tele-Tessar 250/6.3, I might never find out whether is its standard or just a bad copy. _________________ Angry young man !

Here are a couple of pictures....
This is wide open shot. VERY blurred, I'd say that it is unacceptably blurry...
And here what troubles me most. The same shot, also wide open, but I unscrewed the front element a bit, so the distance between 2nd and 3rd lenses became a bit longer. The blur became smaller. So I think the space between these elements is wrong and need to be corrected. Somehow...
If you don't see the difference, click on the pictures and open them in bigger size.
Anyone has an experience of disassembling the back side of Trioplan? How the mount can be taken off this lens? |

No I am sure the focus is on the mug, I used a "focusing lens" in my camera (SONY A77-2, EVF, can increase the focusing point to give precise manual focus). The bag is just darker with little details so you don't just see it blurred... |

Hello Snowcat
The most optimistic diagnose is that your lens is probably decentered, taking into account you didn't provide us the far top right fragment of a FF picture.
I am saying it on the basis of the observation of the characteristic of OOF bokeh shapes (very aberrated) on this fragment of your picture :
My Trioplan 2,8 100 creates this kind of picture then fully opened:

Snowcat, That lens looks to me like it has been assembled incorrectly.
Is the middle element backwards?

Decentering isn't really possible (there's well-fitted, non-adjustable slots for each glass piece) and the middle element can not be flipped. It's pressed fitted into the front optical tube. The back element, however, can be flipped and installed the wrong way. That would be my guess. |

Seems your lens has faulty right. To have very sharp quality images need quality light too, take it out and try it in strong sunshine or use flash and look after pictures again, I had many of these lenses none of them was sharp wide open at all , but quality light helps a lot.
I could never handle it well so finally I did always sell them. _________________ -------------------------------

Ok, I was lucky enough to find a person who KNOWS how to repair lenses. And I was even more lucky to see all the process from behind his back.
The problem was, as I thought, in the third element. In this lens, like in many Meyer lenses, the last element should be centered and fixed in it's position by three screws. Instead of these thee screws it was... glued (!!!) into the very bottom of the place it should be hanging in. So it was closer to the second element AND it was decentered.
This was fixed in 1 hour and the miracle happened. My trioplan now shoots as it should from my point of view... Here are a couple of samples from corrected lens (nothing special, just things in my room).
Thanks everyone for their answers, I really appreciate it! |

Snowcat it's nice you've solved the problem.
The Trioplan 2.8 100mm is famous for its versatility: stopped down it is sharp lens and at full open aperture it creates rather softish portrait adequate picture and the specialty is the bubbly bokeh.
So if you want to be certain of its performance produce a picture with strong OOF specular lights to get bubbly bokeh and observe its quality: mainly the roundness and distinction of outer boundary.

PS
The ways of decentralization might be of various origin: the whole lens barrel or one lens or more of them unadjusted by means of lateral shift or angular one or even the same with a diaphragm.
When speaking of old equipment everything is possible since the human creativity is limitless. |

Today I finally got out to perform some tests under the sun with this lens I've managed to repair. And, I must say, the results pleased me very much. The weather is not right for shooting with such a lens as it definitely requires some grass, flowers etc, and we are having the remains of snow yet.
Here is the album http://www.alphatraveller.org/gallery/index.php?/category/103
Every shot has a writing on it with shooting parameters, including aperture (wrote it manually for each shot).
Now I am pleased with wide open performance. It gives dreamy sense, it give bubbles in bokeh AND it is pretty sharp still. Great lens! |
