What is going on with the ZF lenses

mmmmhhh, on these images, the difference is huge...

The problem is that you never know what the user there might have done wrong when taking the pictures. Since he is not a member here, we can not ask him

But if this turns out to be the realistic difference between the 2 lenses, Nikon will have a hard time to sell his Nikkor 50/1.4 in the future

The tests on the first page he did put focus wrong with the Nikon lens. In the second page the one the link referers to he put the focus correct. The pictures are 100 % crops from a Nikon D2X file with no post processing. Later in the thread he mentions that he has tested 4 different Nikkor AF 50mm F4 to exclude that his lens was a bad one. The Zeiss is much better at wide apertures.

I will do my own tests but I would expect that my findings is the same as the one in the fotosidan thread.
 
Wow

kudos to Zeiss. These ZF lenses seem in this case to be extraordinary good...

And he did not compare the lenses yet for lens flare and colour balance, which is a common problem with non-Zeiss optics

Hi Dirk,

Thanks for the reply..I think UPS tried to deliver my ZF 50/1.4 today when i was out!

Do you have info on why the 85/1.4 is late and production stopped? also do you yet know what other ZF's we can expect later this year?

Cheers..
 
I did a quick test between the Zeiss ZF 50/1.4 and Nikon AF 50/1.4D. I put my D2X on a tripod and used mirror lock and a remote shutter release. For the focus distance I used, approx 3 meters, there were almost no differences between the lenses at aperture 1.4, 2 and 2.8. I just compared sharpness at the center of the pictures. I do not post the pictures because of the almost non existing difference in sharpness. Both lenses are sharp and there is a different character between them. I used the camera in A mode and the Zeiss lens gave approx 1/3 stop brighter exposure (for the same aperture).

However, the Zeiss lens is a joy to use with butter smooth focus and better build quality. A correction to my earlier posts, the Zeiss lens focus ring does not rotate as much as 270 degrees but only approx 210 degrees (but it is still more compared to the Nikon).

This was just a first quick test. I have not compared colors or bokeh.
 
I bought the swedish photo magazine "Proffs Foto", (which in english means Professional photography), and there are tests between AF Nikkor 50mm F1.4 and Zeiss ZF 50mm F1.4 and also between Nikkor AF 85mm F1.4 and Zeiss ZF 85mm F1.4. The tests included sharpness, bokeh, how the lenses handled bright light, colors, distortion and vignetting. The tests were performed on Nikon D2XS and D200 bodies.

For the 50mm lenses the sharpness, distortion and vignetting were equal. They stated that the bokeh was better with the Zeiss lens (there was hard to see any large differencies on their s&les). The Zeiss 50mm F1.4 has better colors (more realistic) and handled bright light better. I can verify the conclusions from the magazine since I own these lenses myself.

The Nikon AF 85mm F1.4 has a reputation of being a very good lens with good sharpness and good bokeh. The Zeiss lens handled bright light better and has better colors. Vignetting and distortion were non existent. The sharpness was equal at F1.4. At F5.6 the sharpness was better with the Zeiss lens in center and corners (the Nikon has very good sharpness at F5.6 but the Zeiss is better!!!). The bokeh was MUCH better with the Zeiss. The colors are more accurate with the Zeiss. They had shot portraits with both lenses and the only "parameter" that was different was the lens. The skin tones were much more realistic with the Zeiss lens.

I know that this are well known "facts" for most people on this forum but I got a bit exicted. I have never thought of the importance of color rendition of a lens. With other words I have never thought the difference was so significant. I found it very interesting that they tested colors, bokeh and ability to handle bright light. These features are often not taken into consideration in other lens tests. Also interesting to see the better sharpness of the Zeiss lens in the cropped sensor size, especially in the corners.
 
It is the colour which make me stay with Zeiss.

Great bokeh are the important feature of new generation Zeiss lenses, it was being ignored when I was playing with Contax. When one was not happy with the bokeh of C-Y 85 1.4, you have to move up to buy the C-Y 85 1.2. Now, you could get great bokeh with many lenses like ZM 50 2, ZF 50 1.4 and ZF 85 1.4. Together with great bokeh, you get nice skin tone as well. Nice skin tone and bokeh goes hand in hand.

I am looking forward to try the ZM 50 f2 MP. The design of this lens is as complicated as the C-Y 55 1.2. I would guess the f2 of this lens will be better than f2 of ZF 50 1.4.
 
Chi,

Which ZM 50 f2 MP you're talking about? What's "MP"? Are you talking about C Sonnar 50mm f/1.5?

I have Zeiss Planar 50mm f/2.0 ZM that I use on my Ikon. In combination with Fuji Astia 100F it produces possibly the most color-accurate photographs I ever had been able to take. I also like it with Fuji Pro 160S and almost any Ilford B&W film.
 
It was a typing mistake. I meant ZF 50 f2 Makro-Planar.

No matter which one you are talking about, ZM 50 2 or ZF 50 2 MP, they both have colour reproduction of the highest quality.
