Lens with Bokeh like Meyer Trioplan 100/2.8?

Andrea, those are spectacular, especially #3 and #6.

In #3, I like how the bokeh is more rounded above the plant and how it is more angular below it, reflecting the pattern of the vegetation.

One of my favourite MG lenses has Trioplan-like bokeh. And it's VERY cheap. It's Fujinon 55/2.2. Very unusual Uthar optical scheme and very pleasant picture.

Then, Telemegor 180/5.5 also has this bokeh

Wow, I like very much last three pictures with Telemegor.

One question about the Fujinon 55/2. Has it manual/auto switch in M42 mount?

No, it doesn't... I had to fix the diaphragm pin (bent it a bit and inserted it with some force applied).

Yeah, I wrote about Telemegor to resemble Trioplan nearly a year ago Very Happy

(In some aspects, I value Telemegor even more than Trioplan - better optics, nicer grass, more aquarel-like drawing, etc.)

And I bet Telemegor 150 or possible some other Telemegors (250, 400, prewar) to be the same

Apparently there will be a new 2015 re-release of the Trioplan, I guess they are trying to keep the wild bokeh so one answer might be “the new Trioplan”. Price remains unknown, as does its effect on the prices of the old Trioplan…


PostPosted: Fri Feb 20, 2015 9:15 pm    Post subject: Reply with quote

Yeah it's very interesting to see the new lens image performance, bokeh, and external look.

Anyway, I think the old lenses will only cost more as time pass, at least in a long term perspective.


PostPosted: Fri Feb 20, 2015 10:01 pm    Post subject: Reply with quote

I do believe it might slowen those big price jumps around some of the lenses (Trioplan 100, Pancolar 80) but nothing more really

After all, are old car veterans getting cheaper in time?

Besides, I've heard it'll cost around €1.000 which is yet far from current Trioplan/Helios average prices. At least for now... Very Happy

Well, Helios 40 are currently produced in Russia on KMZ, you can buy a new Helios 40. But the prices of old H40's are not dropping. Even more, there are lots of people saying that the new H40s are not giving "THAT GOOD OLD HELIOS 40 LOOK", which pumps the price of old lenses further up...

Besides... according to a guy that has all three of them... it's truth.

I still suspect some of the pictures were from Trioplan and got mixed up. Can you explain your processing of butterfly pictures?

99,9% Telemegor. It was August already and I do remember clearly I wanted to give Telemegor a shot as I already prefered Trioplan much more that it probably deserved. I only gave 0,01% to Trioplan for case I'd suffer a premature senility. Good old Trioplan was in my bag too that day Very Happy! Besides, Trioplan doesn't draw the grass this way. I also remember the whole scene, the DOF is absolutely Telemegor compatible (I barely use those stopped down). I barely use anything but MFD and image crop either, and respecting real size of the Polyommatus coridon butterfly and worst, more distant MFD of Telemegor, one thing is clear - it absolutely fits to Telemegor again. File closed!

As I admitted X times already, this series can be disputed. I might have used both lenses and I also used Tair. Hence it's possible to be Telemegor, Trioplan, or even combined. According to sourcefile, I tend to believe it's Telemegor again, as it lacks softness. Btw, sourcefiles of those are really shitty, due to having trouble to actually see anything in this rare midnight sun occasion. It was nothing but blind luck something at least interesting came up thanks to PP. I also do remember troubles with focusing on those butterflies, which would, again, mean rather Telemegor. The thing is, its focus ring was getting stiffer and stiffer (till last week).

100% Telemegor. Trioplan might have been mine already, but I've waited for adapter till June. Carterocephalus palaemon doesn't fly in June here, at least not in this "mint" condition.

100% Telemegor. Trioplan wasn't even part of my equipment yet. Besides, classic Telemegor grass again.

100% Telemegor. Trioplan wasn't even part of my equipment yet. Again, the bokeh and drawing differs.

DETTO.

This can be anything, I linked it to Telemegor just by luck. Could be even Biometar, don't really recognize the bokeh here. I don't consider it important after all, as this photo shows nothing special. Too sharp for Trioplan work, though.

Resume: there are three photos I value more than others - P. machaon, L. tityrus, B. selene couple - and all of them are 100% work of Telemegor.


@ machek great gallery, by the way.

Maybe one sourcefile helps. File representing real sharpness and colors of my copy.

So I was right!!! Very Happy

Hello Woodrim, I deliberately didn't reveal the identity of the lens since it is a shabby, uncoated old one and rather exotic too, so maybe its soap bubble bokeh is not a generic virtue. I still have to collect several of them and then maybe a general trait will be present.
All I can say it is not a Meyer or latter Pentacon product.

Marek, thank you very much, your butterflies are perfect.

Generally allow me to add something on the Trioplan like soap bubble bokeh: it is characterized by the very pronounced sharp circle (the better if it is of rainbow split colors) surrounding bokeh image that is rather dim and better semi-transparent, the best of split colors addition. AndreaEOS' last picture is superb on this, she touched the sweet point of bubbly bokeh creation (that is the distance between lens and the object and between lens and the sensor and a kind of specular reflections that were the subject of bokeh).

Today was a very overcast and dim day, but I still did some basic lens tests of new arrivals. Unfortunately I have no adapter for this one, so I had to hold it in front, but out from the flange using my hand which allowed a lot of light infiltration and no doubt a tilt. This may not be fair to ask, but it is one of the lenses discussed here and I'm wondering if anyone can identify it from its rendering...

Some bokeh shots I've made yesterday. I unpacked my New Year lights for these shots...

Trioplan 100


Primotar 135


Trioplan 50 + 1.7x TC (Promaster Spectrum 7)


Quite interesting that both Telemegors I have (150 and 180) gave no bubbles at all. But I am positively sure that they do give bubbles in the sunlight. So I guess there is some kind of threshold in lights power that give those bubbles. Weak LEDs could not reach Telemegor's limits...


PostPosted: Sat Feb 28, 2015 10:19 pm    Post subject: Reply with quote

Can you show the Telemegor 150 and 180 results?


PostPosted: Sat Feb 28, 2015 10:26 pm    Post subject: Reply with quote

Sorry, I already deleted all that stuff... It originally was made for some initial diagnostic of my trioplan... Telemegors gave circles uniformly filled with colors, just as any modern lens...

I have one more lens that is said to be "like trioplan" - Promura 135/3.5. It's a triplet also and it should give those bubbles too. But there are no bubbles at any f number from any lights. BUT I have not tested it in sunny weather yet...

Minimum focus distance, wide open, point source light some meters away.


I just tested my CZJ 80/2.8 Tessar and it produces soap bubbles, enough that I will hold off any Trioplan purchase. EDIT: Nevermind, it's not very pronounced.

All lenses will give the bokeh circles, but getting those Trioplan-like empty circles is the chore. I received a bunch of lenses a few days ago and am beginning to go through them. Today I tried out the Primotar 3.5/135, but was a dim and cloudy day without significant specular highlights to find for the background. These are about the best I could do today...

I do know the difference, thanks.
I retested in darker ambient light, and it's barely noticeable now... oh well.


I thought some may find this interesting.

Depends on light conditions. My Telemegor is totally different by modern lenses bokeh. It is much closer to Trioplan. I did a series of tests, here is an example of Telemegor 180/5.5 highlights bokeh, too.

I think it depends a lot on shooting conditions, light, distance ...
In my tests with Tessar 50/2.8 (Set 1 picture 5 and all photos in Set2) I got kind trioplan bokeh and bokeh much different as well.

Perhaps in certain conditions the Trioplan can not get any bokeh like Trioplan type Smile
