Mirror less lens mounts - Dawn of a new era for Nikon and photography ! ?

Does anyone REALLY think that Canon did not REALLY think things out before the Big Change...? Sometimes not being the first out of the gate and thinking more long range has benefits.

FWIW, When I speak of objective tests/reviews I am talking about the LENSES not the R body ......and I am not talking about legacy or adapted lenses.
WHY!!!???? A lens is part of a system. "Objective" lens tests without camera info have very limited value. A system is only as good as its weakest link.

DXO does it on a camera which is meaningless seeing as the sensor is the limiting factor.
Didn't lenses of yore get tested with some machine that was the same for all lenses thus they were apples to apples comparisons and not sensor tests instead.

But most of us use lenses with a camera, not without.

True, though definitive resolution is what the lens can resolve etc. If the lens is tested on an old Rebel it might rate very low due to camera resolving issues etc. But put it on the 5DSR and you will be blown away with the superiority of the lens to all others available.
So yes the system is important but like tires you start with a good tire that is independently tested then matched to the auto.

Years back when the magazines would devote multiple pages (much of which I didn't comprehend) on a lens test the camera didn't matter as much. I don't remember them linking lens tests to film tests. Today, each camera only has one type of "film", but with a whole lot more processing choices.
With all the variables it seems that knowing the resolving power of a lens is still a good starting. Then matching it to a camera that compliments it should be easier. I say 'lens first' because a lens is usually a longer term investment ... for lack of a better word ... than a camera body.

And you look at how it performs on that car.

Can’t stop the sensor movement even if you turn off IBIS.
That's too bad. On Panny only, but all mirrorless?

Yes, ultimately I do understand this - but I am wanting to isolate performance of the new LENSES being made for mirrorless and how it may correlate to the new mounts - especially for the previously handicapped Nikon !
Again today at Barnes & Noble, the latest issue of Digital Camera World showed test results of the Canon 24-105 and 50mm lenses for the R camera - and they were very excellent - but nowhere near the numbers for the Nikon lenses ! - so, maybe Nikon has really found something !
I know right now, if I were a pro landscape shooter, and I had money to spend, I would be getting the Nikon !
- and I am NOT a Nikon person...

Nikon has not "found something", if the lens is not performing at that level on the available camera bodies. Canon has always been a system manufacturer. They build things designed to work together.

It's a pretty common thing. There are dampening methods, but the fact remains, the sensor is floating. The camera movement triggers a movement of the sensor in the opposite direction, to help maintain it in a fixed position. Turning off IBIS can't stop the sensor movement entirely. Using IBIS can't help if the camera is accelerated more rapidly or violently than the IBIS mechanism can handle.

Don’t believe everything you you read in a magazine that someone writes as fact! I will say this most the folks write with their personal feelings and are judge mental, being objective is not so easy remember we’re all human.

DxOMark tests lens / camera combinations ..... which just happens to be how we use them.

Of course they test them in a rather sterile environment, which is not how I use them. Studio shooters and to some extent landscape shooters should find great value in DxO testing. Less so for sports, event and street shooters where focus acquisition is a much larger factor. But in identifying a lens for your body, DxO can be very helpful within limitations.
