Nikon D6 coming in 2019 (1 Viewer)

It's got built in IBIS? Does that mean you don't have to leave home to photograph birds? I just wish Nikon would put in some of the mobile phone technology. Some of these new phones have better cameras than DSLRs now, especially in low light.
 
Maybe, still not sure what SR stands for. VR image quality reduces the further from the centre of the image.

For sure it's annoying that Nikon has introduced a new acronym 'SR' on the new 120-300 f2.8 lens and hasn't bothered to fully explain what it is !

The FL glass should contribute to better chromatic aberration control.

Best guess for 'SR' at this point in time is that (as per Marc's post#40) it is a group of lenses which corrects for aberrations. Specifically 'spherical aberration, field curvature, and coma' for fast variable power lenses .

My take on this is that you will be able to have your fast zoom lens cake and eat the prime lens quality too.

SR? Maybe you can switch off VR in the lens and use D6's internal VR (SR)?

As posted above - SR is to do with the new fast zoom lens.

The D6 will have IBIS (in body sensor stabilization - not bin chickens ! :) which will work together with the lenses VR system (dependent on mode selected).

Logically, this will be of most benefit in extreme low light, and/or when shooting video which should be pretty impressive.

I'm sure I read somewhere that ball bearings were to be used in the tripod collar - could SR be as mundane as Smooth Rotation?

What the actual wording behind 'SR' is will prove fascinating and I'm sure have lots of us kicking ourselves over its simplicity !

Assuming that it is to do with that group of lenses (I think? I remember seeing it labeled as such on a lens schematic somewhere - probably posted in one of the links on this thread) , then the probable purpose is to allow a fast zoom lens to resolve like a prime across the frame.

Perhaps something like 'Super Resolution' ......... ? :cat:

SR cont'd ...... ?

Really I'm just guessing what 'SR' could stand for. It could be anything - 'Special Radius' , 'Spherical Rectilinear' , etc, etc ......

Reading through the patent a bit it seems there will be lens groups going all over the place simultaneously when focusing - (I imagine to speed the process up and enhance the accuracy) - maybe it is something to do with that ? ...... 'Super Responsive' , 'Sports Real-time' , who knows ..... ? :cat:

Of course with Nikon's frequent supply issues on desirable product releases, maybe some wag in the R&D department was sending a message - 'Soon Ready' , 'Supply Reasonable' , etc ! :-O

And the resolution is .......

Confusing rumours over the resolution of the D6. 24MP or 20MP? There must be at least a couple of different resolution prototypes floating around as different Pro's have already reported different things. I am pretty sure Canon is doing similar testing and decision mulling.

The rumour also says a mid-Februrary official announcement.

I hope it is at least 24MP but this latest rumour suggests otherwise.

HaPPy NeW YeAr !! :)

Well, contrary to the title of this thread and initial rumours, 2019 has been and going, going, gone ! with no D6 .....

A development announcement was as close as we got (Ditto the Canon flagship 1DX III). The official announcement for the D6 is now supposedly mid-Feb ......

I think this extended gestation, development, and testing period only goes to show the importance of this particular camera. Fingers crossed it turns out to be everything and more people are hoping for ....... and - that it spawns a baby D500S as well :) :cat:

Jeez Louise !!! 3.2kg !!! 120-300 f2.8 'SR' lens

So SR is simply a lens which refracts shorter wavelengths (blue colours) more and thus when used in a lens system corrects all colours to the same focal point eliminating Chromatic Aberrations.

But holy Hector ! :eek!: 3.2kgs !!! ..... no thanks :-C
That's kind of flying in the face of the 'Mirrorless' downsizing trend.

Actually 3.25kg !!!

Nice lens schematics showing the 'SR' lens and how it works ...
https://nikonrumors.com/2020/01/06/...e-fl-ed-sr-vr-lens-officially-announced.aspx/

But jeez - 3.25kg - who on earth is going to use this thing ?! :eek!:

Add that to a D6 say (at ~1.4kg) and you're at a hefty 4.65kg (or 10&1/4lbs !):eek!: for a bit of walk around kit - hope those Pro's are getting paid well !

It will be interesting to see what Nikon does now that Canon has shown their hand at 20MP ....

Ah ha ! - SR stands for ......

SR = (short wavelength refracting) lens

"to reduce longitudinal chromatic aberration" ...... according to an article in DPReview on the new Z mount 70-200 f2.8 S.

Quite heavy lens, 3250 grams, but hopefully good balanced.

Doubt Nikon will update the 300/2.8 VR II with fluorite as well.
