Yes, a good one is worth having. A 2.9/50 Trioplan even better.

I may have an example with issues though it looks clear. May have been opened and messed with or just an example that missed quality control. I had a Super Aubel 28 2.8 that came in with horrible haze (advertised as good) negotiated with the seller then opened and cleaned it. Improvement in contrast was very dramatic. I know what haze can do to your image!

Many possibilities. Imho and others' a bad 135 is very difficult to make! I don't know about any...

Well, all those are ordinary, but the Domiplan is the worst M42 lens ever according to some people. Who wouldn't want to own the absolute worst there is? Laughing Wink

I can send you a bad Domiplan if you're really that intrigued. Personally, I like my good Domiplan better and my Trioplan better yet.

What is the longer range with that extension? I don't want to have to get too close.

Well, I'm not in a hurry to try it and I was half joking anyway. Thanks for the offer though. Smile

the max. range with this 8mm extension is around 50cm. ok for flower portraits...
my main reason for playing with a domiplan is this unique bokeh, i know that there are sharper lenses with better ergonomics and built quality, but you can paint with this lens and produce soap bubble bokeh. (oh, now I have revealed a long kept secret...)
not bad for a 5 euro lens.

Was not a secret, nor the price, although each of mine were around $12.

The Domiplan had issues with the auto diaphragm linkage. Screws coming out of the alloy. It took me two attempts to find one with a working diaphragm. I have an example.
But it is not the very worst 50mm M42 lens from East Germany.
That dubious 'honour' go's to the 50mm f2.9 Ernst Ludwig Meritar. They are sharp-ish in the centre but it is at the edges and in the corners where the real horror lurks.
Insanely the Meritar was still listed as a 50mm for the Praktica MTL5 in the mid 1980s. It must have been only for camera's sold in the GDR.
Both forms of the Meritar are silver/black zebras & are pre-set.

Ditto Miran.

Possibly the worst old lenses are most third party retrofocus wides, from the 1960s.
Doesnt matter what mount, many of course were M42, even more were t-mount presets, but they came in all sorts of mounts. They almost all have dreadful corners.
Even some quite good makers products suffered from that.
Technology has improved a lot.

That said, they are usually sharp in the center at reasonable apertures and you can of course take excellent pictures with them.


My Hanimex 7mm/5.5 fixed focus fisheye is far & away the worst of my m42 lenses. It's hard to get it sharp at the centre & impossible at the edges - there are no corners as it gives a circular image. It's image circle is actually smaller than my APSC fisheye, which is a much nicer lens in every respect (surprisingly the price difference was less than a factor of 3).

One of my CZJ Tessars is pretty bad too, due to stuck aperture & very stiff focus, but it's far more usable than the fisheye and it can probably also be fixed with a few hours tinkering.

Yes, a good one is worth having. A 2.9/50 Trioplan even better.


Haha Smile
I have three Domiplans, one in M42 and two (slightly different) in Exakta mount.
The M42 seems "well-used", the Exakta mount lenses, much less so ... all give perfectly good results for what they were intended for, but do bear in mind they were the "kit" lens of the day and the "standard" print size was the 6x4" enprint!
What minimal comparison testing I've done with my 50mm Trioplan (also in Exakta mount) shows very little difference between the two designs and the 50mm f/2.9 Meritar comes a very close third!
I do suspect a lot of these older lenses have now been "tampered with" in one way or another and may not have been exactly re-aligned when reassembled.
Many older Russian lenses appear to be suffering the same fate!
I prefer to find my old lenses like these still attached to their original camera, often still in the ever-ready case, which can imply they are "one owner from new" and have been simply put away in a cupboard for many years Wink

Back to the original thread ... if we're including T2 mount lenses in this search for "the worst ever", try the Itorex 50mm f/40 (yes, forty) "Pan Focus" lens Wink

The worst lens is not determined by its technical flaws,

but rather by the photographer's inability to utilize it creatively.

As long as you take images just for fun this is true.

There are, however, lots of applications of photography where creativity is not desirable.
Often those are the ones which are well paid.

Of course driving a VW Beetle, a Ford T or a Chrysler Turbine may be fun - but most taxi drivers would go bankrupt using them on a daily basis Wink

I saw some official statistics about the most photographied buildings in the world and in the top 10 there was a farm/house in Switzerland that noone seem to know why.... Wink
