the answer is to why it did cost so little.
Remember it's a 2.8/20 Flek which I paid 99 Eur.
Well I found the reason why. THe lens came with a Minolta adapter mounted on. It was mounted so tightly, that the people of the shop surely thought that the original mount was removed and replaced with a Minolta mount. You could not see any kind of lever that would let you think it was an addition.
But it was enough to screw it off with some force and it went off beautifully - and now I have an absolutely perfect condition 2.8/20 Flek for 99 Euros!

Very Happy

Another one? Hope you didn't turn the filter ring when you were unscrewing the adapter Wink

No, it's the same one I talked about time ago - it arrived to my home today.
Actually, the filter ring was a bit unscrewed, so I screwed it in more tightly.

This Flek is really sharp in the centre even wide open.
This is full image, just thumbnail reference:



As you can see, there is strong vignette in the corners, and corner quality at full size is poor. But in the centre it really gives good sharpness:




Which really goes beyond what I was expecting from this lens at wide open.
I mean, it even causes moiré on the balcony railing. At first I hated this moirè, now I find it useful as lens test feature Laughing when there is moiré on this balcony, it is sign that the lens is sharp Laughing

In my copy, the corners become acceptable at f/4 and good from f/5.6 onwards.
It is a much better copy than the one I first got a couple of years ago (and returned to seller).

V e r y nice results with this lens! So I see a satellite dish, is reception good
with such? And when are you moving into your father's house? Will you
still be young? Laughing

This is what I found with my copy too.

This is one way of looking at it I guess. Wouldn't it be better to start by judging a lens at f8, where it can be directly compared to all other lenses, and then see how wide it can be opened up before the image begins to deteriorate?

I'm pleased you found a better copy of this lens Orio. I've never felt truly at home with your opinion of it compared to the 4/20 - surely CZJ wouldn't have deliberately reduced the quality. Maybe you could put them side by side again sometime soon.

Sad Unfortunately I have lot of work to do and don't have time to work on the move as I should. My mother is old and my GF is in another city, so this slows the thing down. Lack of needed funds does not help with speeding up, either.

Yes Peter, what you say is true, and surely I use wuch wide lenses always stopped down. But I give it for granted that a Zeiss lens gives good performance at f/8 (unless a damaged copy), so my curiosity was to see how it performs wide open.

Well, not deliberately, no... but they made a change in lens design that was conscious. They reduced the front lens size and removed one glass from the optical scheme:

http://www.nadir.it/ob-fot/zeiss_flektogon/flektogon2.htm
(italian, but you can google translate it)

As a result the lens is faster and smaller, and the shorter diameter means better control of the flare.
The price to pay is more corner problems wide open and the glass element removed, a thing which was probably needed to reach the one stop light gain, also has reduced correction of geometrical distortions (this I have not tried yet, I report the results of tests made by others)

Maybe I will put them head to head one day - but don't know how fast or how much because I am not really the kind who makes big comparison tests. I am more of the "party" that one should use the lens he feels better with (not a really scientifical party, I know). Rolling Eyes

Thanks. I'm afraid I can't afford to buy both lenses to compare them, so I'll never know which one I feel better with. I followed your recommendations when I was looking for my 20mm and bought several copies of the 4/20, but each of them was defective in some way. In the end, becoming impatient I guess, I took up Attila's extremely kind offer of a 2.8/20. I'm really pleased with it, but I just keep wondering if I did the right thing. I didn't mean a big comparison test, but just your second thoughts now you have a nice copy.

OK Peter I'll set up a comparison soon Smile

made a quick test shot on the balcony and noticed one good thing and one notsogood thing.

THe notsogood thing is that there is some barrel distortion which I immediately noticed (see the frame of the window) Mad

THe good thing is that this lens delivers an impressive 3D rendition, which I did not expect from this type of lens. Shocked

here's the sample:
