Today I receive a contax 100 macro planar from ebay.
I take my giottos to clean few dust on front lens.
Something was ejected on the glass and doesn't leave with air.
I tried a brush, a microfiber cloth but nothing help.
I was ready for the heart attack. A scratch in a 450 euros lens
At the end I used eclipse and it clean in 10 seconds.
I think it was a small insect ejected from the giottos
Be careful with giottos or better use Russian lens

Ah so it was you to win the auction by the Austrian seller!
I wanted to bid, too, but then was scared away by the fact that the seller could not apply for the full Paypal protection program.
Congratulations, you now have what is one of my dream lenses. _________________ Orio, Administrator

In this case the seller used Paypal but having less than 50 feedbacks the coverage was only 200 Euros. He was a private not a shop so I did not have the courage to bid. Congrats to poilu who had the guts and took home a fantastic lens for a great price. _________________ Orio, Administrator

@ Orio
the 60 s-planar I buy for 230,- euros is a dream lens. Wide open it give full contrast & resolution. I tought the 100 would be the same but after few shot it's not the same class wide open AND have CA on my 400D. The same as the 28-85 who have the same great quality with 35-70 but have CA.
for me a dream lens should not have CA but I could not find info on the net for the 100 macro |

Maybe you have a bad copy. Have you inspected the lens well for possible hurts?
The Zeiss specs (and as you know, Zeiss is the ONLY company to make MTF tests on actual production copies instead of prototypes) show clearly that while the M-P 60 has higher central resolution, the M-P 100 has higher edge resolution, uniform rendering from centre to edges at all apertures, practically no vignetting (while the 60 does vignette by admission of Zeiss itself), 1:1 reproduction and most importantly, 0% distortion (yes, it's not a typo!).
Zeiss explains their choices by saying that the 60 lens, with the higher central resolution and lower edge resolution, is ideal for macro of insects or other subjects where the centre of the frame is very important and the edges are usually only background, while the 100 lens with it's zero distortion and uniform rendering, is ideal for the reproduction of documents, paintings, or any subject where the edges matter as much as the centre.
In any case, if you plan to sell the lens, let me know, I may be interested. Of course in that case I'll want to be able to try it first, but I am sure that we can work out a solution.
Would you please post some 100% crops where the CA happens? _________________ Orio, Administrator

Your pbase links seem to have a problem poilu.
EDIT: the images on the pbase site are visible, maybe they are stopping external links.
Anyway - your "cat"'s eye looks very soft - that seems strange to me, because the mtf charts speak of a lens that is, wide open, as sharp as, or even sharper than, many other tele lenses stopped down.
I remember having seen a sample of a dollar bill shot with the M-P 100 that was outrageously sharp and detailed.
Could you please try to shoot a steady object with a tripod? _________________ Orio, Administrator

Yesterday I go to a photographer who still shot with contax. He keep the lens for a weeding and gave me a 80 2.8 to 'play'.
My cat is from the 400d without level and sharp. For me it's not soft but I am beginner front of master orio
Here is a test from french magazine chasseur d'image.
vignetting at 2.8 is 0.5 for the 60 & 0.4 for the 100
distortion is -0.2% for the 60 & very low for the 100
but 60 perform better
if you understand Italian check http://www.geocities.com/ilprode/TestZ.htm
where they found 0.7 vignetting for the 60 and 0.6 for the 100
I add a pic with the 60 (this one is really soft ) but you can see no CA on my cat |

hey poilu, maybe I went a bit too far by saying "very soft", but that was because I remember other pictures taken with this lens that were "mind-blowing sharp" if you know what I mean, so mine was a "reaction by contrast"
Your 60 macro has one of the highest resolution values in the centre of the lens of ANY 35mm format lens. It is close to perfection.
What I was pointing to was the fact that there is significant different in resolution from centre to edges with the 60 lens, while the 100 lens is more homogeneous and therefore better for some type of photography.
Your "cat" is certainly best photographed with the 60 lens, given the type of subject.
What I don't understand is why you bought the 100 lens at all.
If you were happy with the optical rendition of the 60 model, buying the 100 is a waste of money. By simple use of extension tubes you can reach the 1:1 size with the 60 model also. The only reason to buy the 100 would be to take advantage of the more balanced centre-edges resolution, for photographing paintings, or architecture details, while knowing that performance-wise, the centre of the 60 lens is still unbeatable. _________________ Orio, Administrator

Attila, do you think it's possible to give the Edit and Quote buttons two different colours?
Maybe give the edit button (which only moderators + original poster can see) a red colour, so that it becomes like a warning sign. _________________ Orio, Administrator

Every brand has inferior copies, even Leica. I bought a 35mm Elmarit last version to be a double of the lens that I already have, because it is one of my preferred lenses.
But after I tried it I noticed that it was not sharp like my first copy.
Luckily the second copy had a couple of light scratches on the front glass that the seller did not mention ( and not even notice probably). So I could return the lens.
I have two Planar 1.4/50, one is softer but has a better bokeh, the other one is sharper with a worse bokeh. Since the lens is cheap, I am keeping both.
I have a similar situation with the Distagon 2.8/35, I have two copies, one has incredibly good 3D effect, the other one has less 3D effect but it's sharper. I am still undecided what to do with them, because I like both things.

I would never buy a manual focus zoom, even if excellent as the Contax 35-70. Zooms are optical compromises, and if I have to compromise, well, I will compromise completely, and buy an autofocus zoom with image stabilization. Half compromises are even worse than full compromises.
You are really crazy in buying 3 zooms of the same type, I agree with you

Yes: work on photographing. Take trips, take photos, make prints, make a web gallery, try to get the most out of the lenses that you already have. I used to do that back in the times when the only prime lens that I could afford was a used MIR-24N. I still think it's a valid remedy. Best of all: forget the digital, get back to film photography, to B&W, get a medium format camera and make big wall prints. You will find out that you can obtain much more from a modest Biometar or MIR lens mounted on a 6x6 camera, than from an expensive Contax mounted on a 24x36 or digital reflex. Size does matter. _________________ Orio, Administrator

Thanks for the interesting samples, poilu. Bank notes are an excellent benchmark test for macro performance.
Judging from what I see, I would say that the Makro-Planar 100 and Makro-Planar 60 are on the same quality level, perhaps the 60 lens has a little more microcontrast.
The Tamron 90/2.5 and the Pentax 50/4 appear much softer, definitely the Makro-Planars seem to play in a different league.
The one astonishing thing about the Makro-Planars is, they seem to perform wide open just the same as stopped down, or almost. But I knew these things, that is why I told you these are dream lenses for me. But one day I will manage to buy one!
And... my offer is still valid, what do you do with two Makro Planars? if you decide to sell the 100 lens, please contact me first, I want the priority _________________ Orio, Administrator
