We are hopeful a Nikon adapter will allow older-designed lenses which are NOT fully electronic aperture control to work with a fully electronic system in the new Nikon mirrorless. My point is Nikon is making new mirrorless lenses, so there must be some advantage to how well those new mirrorless lenses will work with their new fullframe mirrorless cameras. So older lenses may be usable on the new cameras, but probably wont perform as well as their new mirrorless lenses. We will see if Nikon solves this dilemma . That is key to keeping their folks in camp. Cheers

It is not really hedging your bets--just superior sensor technology.

As far as Nikkor lenses are concerned: you will be able to use them on your DSLR as they "fail to suck," as you so succinctly state. No problem here.

If you want to use current F-mount Nikkor lenses on the new Nikon mirrorless system you will need an adapter, as we all know. That adapter may or may not work very well. A key issue is the different flange focal distance. This is the distance between the sensor plane (or focal plane) and the lens mount (or flange plane). In the Sony E mount this is 18mm (the other mirrorless systems are in the same ballpark), in the current Nikon F mount it is 46.5mm. I am not sure what the distance is in the new Nikon mirrorless system, but I would assume that it will be close to the Sony E mount. (We will find out on 8/23.)

Not only shorter flange distance but also larger opening meaning faster, smaller, lighter (pick any two) lens designs will be forthcoming.

The much shorter flange focal distance allows for a different mirrorless lens design that is lighter and has fewer elements, and the camera in turn will be designed for this short flange focal range as well. This is a further reason why your old Nikkor lenses may work sub-optimally on the new Nikon mirrorless system. So Nikon will be under a lot of pressure to come up with native mirrorless lenses fast--just as Sony was when they brought the first mirrorless full-frame camera to the market in 2013. Nikon certainly will be able to do that, but it will take time. Keep in mind that Nikon still has to develop this expertise. It also will take time for third-party providers to build native lenses for Nikon mirrorless, although they may be able to adapt designs of lenses they built for Sony. There finally is a pretty complete lineup of native full-frame lenses for the Sony E-mount--I would expect a similar time lag for the Nikon mirrorless system.

Glad you like your Nikon system and it works for you.

However the facts are that the A9 focusing system is the fastest on the market. It has 695 phase-detection and 425 contrast-detection points covering 93% of the frame. Super for autofocus acquisition and tracking of moving subjects from corner to corner of the frame. NO DSLR, of any make, at any price, even comes close to this focus coverage. Plus the A9s exclusive stacked front-illuminated image sensor and processor allows for true 20fps shooting, with NO viewfinder blackout. Again, no DSLR can do this. This is a game changer for sports and wildlife shooting.

Hey not everyone can afford this lens and this camera, I get that. I use both my Sony 70-200mm f2.8 G-master lens and Sony 2X extender, as well as my Sigma Contemporary 150-600mm f5-6.3 lenses on my fullframe Sony A7RIII, A7III and my APS-C A6500 for sports and wildlife. But I do get the same great focusing system (with 93% coverage) of the A9 on my A7III. Cheers

You can't deny his 99% keeper rate. You don't know how much he shoots and he seldom shows any images. Of the two I saw one was a keeper. I guess the next 98 were keepers also.

It always amazes me how half the time "It's the photographer, not the camera", while the rest of the time we wrestle with what brand is better.

Life is good that we don't have to work all day every day for our next meal.
