Optics Theory - This forum is aimed towards the TECHNICAL side of photographic OPTICS THEORY. There will be some overlap by camera/manufacturer, but this forum is for the heavy duty tech discussions. This is NOT the place to discuss a specific lens or lens line, do that in the appropriate forum. This is the forum to discuss optics or lenses in general, to learn about the tech behind the lenses and images. IF you have a question about a specific lens, post it in the forum about that type of camera, NOT HERE.

Here's my beloved damaged HC f2, exquisite when it behaves. Marked Tokyo.

So we don't know if it's a Sonnar or not.

Does it have a soul or is it cold?
There will hide the answer.

from the nikon site, re: 105/2.5:

Compared to the previous model with Sonnar type lens construction, it offers significant improvements in close-range aberration fluctuation, as well as peripheral light, spherical aberration and coma. In particular, it delivers a beautiful balance of focused and defocused (blurred) images, as well as higer resolution with natural gradation. The Xenotar-type lens design with the ideal aberration correction made it the perfect lens for portraits.
Can someone post some Xenotar pics? Any Xenotars available in LTM?
best,
Alex

Check out the Canon 50/1.4 LTM, for instance on the flickr M-mount forum (see my sig).

Hi Raid

could be, but probably mostly nostalgia, like Kodachrome, where even though we know the colors and grain patterns don't reproduce as accurately as newer films, some people will always like them because they remind them of a certain time or memory ...

The Olympic Nikkor and Millenium Nikkor are not Sonnar formula lenses. Neblette, "Photographic Lenses" lists the Olympic Nikkor as having the same block diagram as the Canon 50/1.2, but this must be an error. I have seen (somewhere posted) an X-Ray of the Olympic Nikkor showing it was not a Sonnar, but it was different from the Canon 50/1.2. I have taken the latter apart, and made one from two parts lenses- thanks to Roland for providing one of them.

Interesting reading. It mentions how Nikon patents were the product of German-Japanese cooperation and how Germans designers contributed to them. Politics may have more to do than optics in the quality of Japanese Sonnar types. <A HREF="http://old.photodo.com/art/When3.shtml">When Japan took over</A>

Ted,
I am not a Sonnar fanatic by any means. I sold several lenses, including a Tokyo Nikkor 5cm 2.0 to buy a Leica lens. The Sonnar lenses are a nice alternative.

Hi Raid

I like the Sonnar look occasionally, it's basically a lensbaby or Holga like fun distraction once in awhile.

If we were back in the '30s, and that's about all there were, it might be a different story...

Your pics of the sutro baths are sublime. 80mm Komura? Superb! Wow!

The Nikkor 105/2.5 is razor sharp and it is a Sonnar. It is not even close to a soft lens.

I do not have any scanned in with the Zeiss Opton 50/2. I have two of them, one shimmed for a Nikon RF and the other is on the Contax IIIa. "Personal opinion"- very close, the edge goes to the Zeiss. I have 5 of the Nikkor 5cm F2's beween S-Mount and LTM.

I will have to do a "Sonnar formula 50" shootout. I have a number of them. I have an M-Mount adapter with an indexed-cam, thanks to Roland.

I also have a 5cm F1.5 Post-War CZJ Sonnar which is "tweeked" from the pre-war design. And the Carl Zeiss Opton 50/1.5, and later Carl Zeiss 50/1.5. Canon 50/1.5, and of course several J-3's.

Hi Raid

The F mount ones, post '60s (5xxxxx +) are not Sonnars and have many corrections over the previous ones.

My 105 Nikkor lenses are all Sonnar, and they are amazing.

Here's what Bjørn Rørslett has to say about the Sonnar (pre-1972) version of the F-mount 105/2.5: "The Sonnar is easily identified by its smallish rear element compared to more recent versions. It was an extremely sharp lens for its time and the optical quality still surpasses that of many modern lenses. It underwent cosmetic changes of the exterior only and stayed in production until 1971. It is a great performer at f/5.6 and provides for good performance even wide open, but flare could be a problem here."

They are probably all amazing.

But the later ones are optically even better than the Sonnar ones:

Sonnar's are known for having high field curvature. It does not do well for flat objects, but this can be an advantage for taking portraits.


I am a Sonnar fanatic. I have ten Zeiss Sonnar 50 F1.5's alone, all a little bit different. I have even more Nikkor 5cm F1.4's, mostly to go with Nikon RF's.

Raid - great photos, I doubt those could have been any better with the newer 105/2.5

Brian - I do more than portraits with my 105/2.5, so I like flatness of field. A great lens for portraits is a 75-85 1.4 to 1.8

Here's another with the 105/2.5 p*c post Sonnar version on a d40x:
