I had a "Zebra" Gorlitz that was in very good condition. A nice close and beautifully fine and very sharp middle distance lens between F5.6 and f11. Pretty ordinary outside of that range, except for some nice bokeh at f4 and f2.8. Gets poorer in sharpness as you focus to infinity. At infinity the sharpness falls off considerably. Chromatic aberration also increases to noticeable levels around infinity. Defo not a wildlife lens unless you are shooting digital and your sensor, processor, and software editing system can assist in better longer-distance image processing. I use film, so none of that gets in the way of the reality of this lens. A very nice urban 'round town lens, but a bit heavy and bulky. But otherwise really easy to use, though. So simply put together that it's easy to open up and clean out a dirty-glass version. I got mine cheaply. Try not to get ripped off with anyone wanting more than $30-$60 as there are some real profit-seekers out there for this lens pushing the "bokeh monster" hipster cool, thing. Nice bokeh, though.

I bought this lens in a charity shop. They wanted £10 for it and it had notable fungus and both caps so I bought it.
My first real go at opening up a lens and cleaning (with much help from kind forum members) came up with a clean (or at least as clean as I could get the front and back elements, (I did not chance my arm by going any deeper).
Result!
This lens is not the sharpest available at 135mm, I have a couple of sharper ones but sharp does not equal best. I sold two CZJ 135mm F3.5 Sonnars (M42) over the past couple of years as I had F2.8 lenses that were as sharp and in K mount but not this one.
The bokeh is great, the handling is good with a lovely long focus throw....but not the best min focus distance.
The weight is a bit much, so I tend to use a flanged M42 to K adapter for my piece of mind and not worry about infinity focus. Not a problem as this lens is probably at it's best for subjects not at infinity and have that bokeh.
I nned to take some portrait images with it as this is where it should really shine.

I picked this up in an outdoor market a couple of days ago, the early zebra-striped version. Mechanically good, but the rear element looks like someone tried to clean it with a scouring pad and is generally a bit whitened and misty. Results are a bit soft, but surprisingly good considering its condition. My main reason for posting is to mention that this one has an interchangeable mount that isn't mentioned above - Nikon bayonet. It looks professionally made, but the finish isn't a close match to the rest of the lens, it's blued machined steel, not painted. It's an extremely good fit to the camera, much better than most Nikon-fit T-mounts etc. I'm guessing it was made to order for a customer, rather than being a regular product.
This is a block of flats a few hundred yards from my house, it makes a good target for lens tests. This was taken at 1/2000th f11 in winter sunlight. Unfortunately the camera is overdue for a good clean, as can be seen from the marks in the sky to the right.
And this is a soft toy, distance 1.5 metres, 1/60th f8

Mine is the zebra Meyer-Optik Görlitz Orestor 2.8/135 preset version, M42 mount. It is very well built; feels like you could drive your car over it without damaging it (but I'm not trying!). In use, it has amazingly smooth focusing, but a very long focus movement, maybe 340 degrees from infinity to closest focus (1.5 metres, or 5 feet). You're not going to focus on any fast-moving objects without a lot of practice! Surprisingly to me, the aperture ring is further out from the camera than the focus ring (somewhat in the style of rangefinders lenses). Even more surprising, it is clickless; the first such lens I've come across.
When I first used this lens, I struggled with getting focusing and exposure right, as I often needed to open the aperture up to focus, then close it down to match exposure information. What I hadn't realised was that this is a "preset" lens, or indeed quite what that term means. There is a decorative-looking ring just beyond the aperture ring, with a red dot on it, which in my case was set against the 32. Slide that ring away from the camera and you can turn it so the red dot matches any other aperture value, and the lens will then not stop down any further than this. So the idea is to meter first, set the red dot to the chosen aperture, open it up to frame and focus, then a simple twist turns it (clicklessly, smoothly) back to the chosen aperture for the shot. Not quite as simple as my K-mount lenses, but better than other M42 lenses I have tried.
Looking into the lens from the objective end, the most obvious thing you see is the fantastic set of 15 aperture blades. Yes, this lens does create smooth bokeh, and great subject isolation.
Mine shows no obvious signs of coating; I'm guessing from the lack of flare or CA that there is at least some single coating. I also felt there was good colour and contrast, and (bearing in mind the limitations of film in terms of resolution) excellent sharpness. It seems to me to perform way better than my Pentax-M 3.5/135. I expected to try this out and then move it on straight away, but there's definitely something holding me back.
Edited to add some examples, all taken on film on a Pentax MX:
1) Rare example of apple flower and ripe fruit, f/2.8
2) Nice bench, not sure of aperture
3) Statue in Kenilworth Castle garden

"PENTACON 2.8/135 Made in G.D.R.", m42 mounting, serial: 7007xxx
I love this lens, sharpness is outstanding, colours and contrast are superb...
Don't need to mention the bokeh, do I?
The 360º focus ring gives you a precise focus, but when you want to go from near to infinite could be annoying.
Outside you must be careful because it is prone to flare, a lot, even with the hood and a filter mounted on, but in the shadows it's perfect...
If you are photographing in low light a tripod is probably a good choice.
I bought this lens on ebay in very bad shape, rust on iris and in some parts full of oil, the lubricant evaporated and condensed on the front and rear element, particles of rust felled into the front element, the focus ring hard to rotate, and the body would wobble... It took me a full day to fully disassemble, de-rust and degrease all the 15 iris blades, clean all the optics, bluing the iris blades to protected against rust and avoid internal reflexes. Reassemble all the 15 iris blades eas hard ( damned this took me 2 hours, but the last try only took me 15 minutes to reassemble the iris), but all this work paid off.
One example of colours contrast and sharpness:

There is a lot of confusion already on this page. First of all, the lens should simply be named the "Pentacon 2.8/135" since that is what it says on the barrel. VEB Feinoptisches Werk Görlitz manufactured many preset versions, starting in 1965. The first was indeed branded Meyer-Optik Orestor and appeared in zebra styling. But the second, branded Pentacon, was also a zebra. Then followed no fewer than eight other variants. What they all have in common is the preset 15-blade aperture. The later "Auto" and "Electric" versions have automatic apertures, only 6 blades and do not compare on image quality. They should be considered a different lens, so the review above is out of place.
What I like about this lens is its modest weight and length, which increases only a little when you focus down. It has a dedicated screw-on hood, which you may not at first realise is removable. The minimum aperture of f/32 is more than most. The preset mechanism is a joy to use and the focus ring is large and grippy. The rendering is yellower than Pentax, which creates a lovely "old world" vibe. Sharpness is decent and perfect for portraiture.
What I dislike is the minimum focus of 1.5m, which is too long to be comfortable. However, this is the same as the Taks and no-one complains about them. My copy is very difficult to focus and tends to unscrew from the mount if I am turning in the wrong direction! But that is a matter of age. I can also dock the lens marks on sharpness, if I compared to the very best. Purple fringing is easy to create but also easy to destroy in software. You should not expect the sort of micro-contrast possible with more recent designs.
But for fifty quid this is an excellent addition to anyone's toolbox, providing you don't mind metering manually. Actually the preset mechanism rocks! And as I experiment further I am finding nice subjects for the way this lens draws an image.
More details and photos on my blog.
(By the way, I do not believe in assigning a numerical rating so ignore that.)

the BOKEH MONSTER or BOKEH KING.
this lens was made for one particular specialty purpose, and that is to take great portraits at 135mm. there is nothing to hate about this lens, it just takes some really smooth and creamy bokeh. it's really a wonderful lens. the sharpness is pretty good at wide open and gets better stop down. very sharp at 5.6 - f8.
of course, there are other 135mm with better IQ sharpness and contrast like the K135/2.5, F/FA135/2.8, 135/3.5 (Pentax or CZ) and the MC 135/2.8 variants, but those lenses dont compare against the Pentacon or Meyer Orestor in terms of bokeh. it just rules over them when it comes to smoothness and very nice softy colors. what's better is that this lens has 15 aperture blades which makes the bokeh circles consistently circular at smaller apertures, thereby making the images more pleasing to look at.
the downside of this lens that it could pretty much flare up and lose a lot of contrast, not to mention that it's only single-coated. that's why a deep hood is necessary whenever you use this lens. aside from that, a very outstanding lens.
9/10
