I had one. This is one of the lenses where the idea goes behind feasibility. I do not know any other lens that is so much prone to halos and koma.

I agree... it is heavy, it's difficult to focus precisely, the lens has tons of CA, halos, maybe the design shows all currently known optical aberrations (maybe it has even the currently unknown ones Laughing ), but it simply WORKS




And that's the reason why I keep my copy Smile

Furthermore my lens was even cheaper than the Canon FD 135/2.0 today. I don´t remember the price I payed for that lens, but in those times I didn´t spent that much on photo equipment with dubious quality, and that scratch on the front lens was an good point to deal on the flea market.

hello

i have buy the carbonR's beroflex 135/1.8 witch is exactly the same as samigon listed here http://www.pbase.com/pganzel/samigon_135mm_f18_on_maxxum_7d
same color ,exact copy

but ,after a lot of search on the web ,i find ,in an asian forum ,there s different optical shemes
sigma YS has it s own design 6/5
after there s the soligor type ,this is the one dismantle by P Ganzel whith the big triplet .it s a 5/3
certainly same optical sheme under different names
and the 3rd version ,the spiratone ,whit 6/4 optical design

all of them are sonnar type i think

mine ,when i look trought whith a light source seems to be very similar with the spiratone first a doublet and after a single element



it will be interesting to know who have best quality/resolution ,and who made what

Attila: Thanks!

AMDBill: Nice find. Thank you.

True (or typical) Sonnar is the one in the Ganzels drawing. The other two are heavily modified Ernostars (the Sigma has slight gaussian touch).

I took my Spiratone, flashlight and... voila, we have 4th 135/1.8 design in list...

My Spiratone isn't like the pictured one, I have the older model, which has different look, is native M42, doesn't state "Auto" word in it's name, but:

"1:1.8 f=135mm No.532xxx lens made in Japan SPIRATONE PLURA-COAT By Mitake"

this one has 3 elements in front group (none is cemented) and rear group consists of cemented doublet... seems to be Ernostar with rear element replaced by cemented doublet... something like:

I like this post very much.

I saw a soligor (very old from the 60's) and perhaps it's a sonnar type lens, like you say.

Excelent to know the performance of the three and who made which.

Thanks to share your interest.

Rino.

I owned one under a different brand name a couple of decades ago. It was impressive in size and weight, but it was rather soft wide open. At about this same time, I acquired one of Vivitar's legendary 135mm f/1.5 "Professional" lenses. Talk about soft wide open! Anyway, I didn't see much use to keep the 135/1.8 when I had the Vivitar monster so I sold it.

There's a fellow on Flickr who has a Spiratone 135mm f/1.8, and who's taken a bunch of shots with it and his 5D. Here's his '135mm' set:

http://www.flickr.com/photos/mattbenn8/tags/135mm/

It'll give you a pretty good idea what the capabilities of the lens are. Me, I think it works better with a DSLR than it did with the old film cameras I used mine on -- if mine was even the same optical formula of the Spiratone, which it may not have been.

To help keep the discussion more clear, please specify the filter size of the lens you are referring to. There were 135mm f1.8 lenses with an 82mm filter size and later version(s) with 77mm.

The one I had, which I think was a Sigma, was 82mm. M42 mount. It was pretty old.

Ah fun seeing my thread filled with amazing info!

I have yet to try my sample out under conditions for which it's made, or so I think. During the day with the sun out it's indeed not the prettiest lens, but I'm thinking of taking it with me on a gig when I to one with harsh lights.

With a flash almost any lens shows good results...

I never liked the 135mm f/1.8 Eyemik I had, indeed due to the abundance of coma. This lens is very picky and works well with isolated subjects.

Some of you may remember my Y/S mount Sigmatel Multi Scalematic 135mm f1.8, which is razor sharp at f4-F5.6...It has a 77mm filter thread.
I only have a kitchen scale which is'nt very accurate but it gives the weight of the bare lens, with a Y/S-M42 adapter fitted as 825g. With both lenscaps, an M42-SA adapter plus a Sonia Brand 77mm lenshood fitted the weight according to my kitchen scale is 950g.
I have tried the trick of shining a torch through to see how many elements it has but I cant see anything so I have'nt a clue which of the 4 types it is?

The lens is listed in the "Kadlubek’s lens catalogue" for 130 EUR. That is a appropriate price I think.
On ebay I think you can start around 180 ...

I bought mine a long time ago, I suppose that the price on the flea market was under 100 DM - which is now only ~ 50 Euro.
But the lens had a big scratch on the front lens, some 50 millimeters long.
Without long shade the contrast is often very, very bad.
Furthermore I found some mild fungus on the inside of the last lens.

The last Ebay auction ends at 231 Euro!
