My guesses:
- the 65mm f1.8 is indeed a macro lens, it wouldn't make sense otherwise
- the 120-300 f2.8 SR announced yesterday was designed from scratch to AF optimally on both F and Z mout bodies. This is the only way such a strategic release would make sense and Nikon does make sense 99% of the time for such matters.

Cheers,
Bernard

Don't DSLR and mirrorless cameras AF fundamentally different. That is why mirrorless designed lenses AF faster than DSLR designed lenses that are just ported to mirrorless. That is what the results were on the Sony system where Sigma lenses redesigned specifically for mirrorless AF faster than that same lens that was designed for DSLR.

That was the theory prior to FTS introduction I guess.

But when I see the level of performance I am getting today with the Z6 + 200mm f2.0 or 105mm f1.4 I have doubts. It seems to be a generic belief that is highly impacted by the technology being deployed. Like to old belief that CMOS was more noisy than CCD... ;)

And Nikon has gotten it right even with pre-Z legacy F mount lenses, I am sure they could design F mount lenses that focus even better through the FTZ. And I guess this is what SR is about.

But I could be wrong of course and will have no issue to admit I was if I am.

If this is real it looks better than I expected. The focal lengths and zooms are most of the things I would want, granted within certain weight/quality numbers and not outrageously expensive.

Call me a cynic but that looks like fantasy. We are still waiting for any sign of a 70-200 and the 85 is announced but not shipping. To deliver that roadmap Nikon would really have to up their game next year.

Yes i am sure you are right but i think that Nikon owners of a long pro tele simply will have to use the converter so it will work on either a D6 or a Z.
Usually these people have invested in D5 bodies and Nikon wants to sell them a D6.
Probably the latest long telelenses have been optimized for both Z and DSLR and might have an option to be converted to the Z-mount later on.
or maybe this 120-300 is the first.
(The D6 has to be very good to be able to compete against the Sony 9 markII; then what will Canon release?)

i just took a look at the impressive lensdesign of the 24mmf1.8 S

The elements near the camera have a very particular shape. Especially no2
Maybe it is just the drawing?

No pro telelenses for the Z till 2022...or later...
The 65 f1.8 is an odd one, maybe a macrolens?


A 65 mm f/1.8 would be a welcome prime in a cinematographerís kit.

What is special about 65mm from a cinematographer's perspective?

Simply that there is too much difference between a 50 and an 85.

Some, like Cooke, solve this with 75 in the lineup instead of an 85. Ziess, on the other hand, has long had a 65 available.

The new 85mm f1.8 appears to be as good as the Otus 85mm f1.4 at half the weight. A bit worse at infinity but better bokeh and coma. Similar color correction.

Cheers,

Half the weight but f1.8 and not f1.4...
and extreme corner unsharp until f8... i think that is really bad for a (new nikonS) 85mm.
(the Zeiss Mivus 85mm has something similar)

Looks like both Canon and Nikon will have the f/1.2 "holy trinity": 35 1.2, 50 1.2, 85 1.2.  Nice...

At infinity, which is clearly not relevant for portrait work.

The choice today is either using aspherical elements and get ugly off highlights bokeh or not use them which results in a smaller enveloppe of usage that can optimized (in this case some compromise at infinity).

I far prefer the choice made by Nikon not to use aspherical elements in this lens. Zeiss is indeed making similar design decisions. Besides, it's far from poor at infinity at f8, which is the aperture I would use for landscape work anyway.

Cheers,
Bernard

Indeed.

But probably with slightly different design decisions considering what we know about the Nikon 50mm f1.2 S. It seems that they have imposed on themselves less design constraints in terms of bulk, meaning that we can expect better performance at the cost of more weight.

Nikon is clearly going with the following logic, although their marketing dpt has omitted to explain this...:
- very good and light - f1.8 range
- no compromise but bulky - f1.2 range

Cheers,
Bernard

Use of Nikon Z6 and Z7 on a safari
« Reply #197 on: September 17, 2019, 11:17:02 am »

Article by Thom Hogan where he used a Z6 and Z7 on a safari.
They seemed to work quite well on the trip. Amazing images.

The most arresting quote from this article for me was this one:

Quote from: Thom Hogan
The Sony mirrorless would be better. Nnyaa (in Setswana). It would only be go sa tshwane (different). I probably would have picked the Sony 100-400mm lens instead of the Nikkor 500mm, giving up some reach for flexibility. In my experience I'd probably also have many more "almost perfect focus" in capturing motion with the Sony instead of the "dead on focus" shots like I got with the Nikon.

The most arresting quote from this article for me was this one:

Yes. Most online discussions about AF involve:
1. people with only very limited experience of systems others than their own
2. an idealized view of Sony AF performance vs a worst case scenario for Nikon mirrorless

The reality is that both systems have + and -.

Bernard
