The basic thing I wanted to tell is:
- Zeiss ZF lenses are in no way better than great AI lenses.
AI(s) Nikkors 2/28mm, 1,4/50mm, 1,4/85mm, 2.5/105mm are stellar lenses.
Maybe you can get some scientficly better results, but you don't see
any diffeserence in your picture.
Personal experience? Did you compare the Zeiss lenses with the Nikkors?
- Maybe ZF 2.8/25mm and 3.5/18mm are a little better than the old SI
Nikkor equivalents, but it's definetly not worth the money.
Already the AF-S 14-24 blows away the old primes, and you see clearly how even a newer AF 2.8/20mm falls off. The Zeiss 3.5/18mm is pari with the Nikkor Zoom, as far as I can tell.
- I am German, I am an engineer, I like German engineering, but Zeiss
ZF lenses have nothing in common with that. Zeiss ZF lenses are made
by Cosina and Zeiss only sells the label to them.
There is a misconception that only German labor ensure quality. Lens quality depends on the design. Zeiss relys on its reputation of producing on the best optics in the world: Zeiss makes most of its money designing optics for the semiconductor chip industry. Cosina can build excellent lenses: as for any lens manufacturer its all a question of the price.
Your arguing in favor of Nikon contradicts you point.
It is the same as
the Leica lenses on the panasonic Lumix cameras - they just make
money from the label. Zeiss lenses made for Hasselblad, made by
Yashica for Contax are something totally different.
I recomment to get a Zeiss less first, test it and then judge, not judge first without and knowledge of the lenses, please!
- For the money you have to spent on a Zeiss ZF 2/100mm you get e.g.
the AI(s) Nikkors 2/28mm, 1,4/50mm, 1,4/85mm, 2.5/105mm and a 4/105
micro in great condition.
Once you take on of the Zeiss ZF in your hand, you will realize there are as good even better in the building quality that the old Contax Zeiss lenses "Made in West Germany". I know what I am talking about: i own 3 Zeiss lenses for the Contax IIIa range finder and 3 Zeiss lenses for the Contax/Yashica lens mount! The ZF lenses are full metal lenses, not such wimsical plasic constructions, and the focus ring can be turned extremly smoothly, smoother than my old German Zeiss lenses.
I have not handles such high quality lenses for a long time.
I extensivly hat the change to play around with the ZF 2/50mm Macro and the 2/100 mm. Even though, I did not have my tripod, I could see that the 2/100mm has in IQ which blows you away. It has a chispness and contrast already wide open at f2 which non of my Nikon show. The bokeh is even better than my 70-200VR.
Originally I wanted to buy the AF-S 105VR but after seeing these performances, I most likely will buy the 2/100mm now.
