Arrival of Nikon mirrorless (finally!)

[Ilkka Nissilä]

Actually we only have rumored opening diagonal/diameter,,,

Okay, I thought it came from a patent but I didn't read the patent text myself.  Let's see how it turns out when the products are available for testing.

These lenses will be huge, glass diameter, very well APO corrected and therefore very very expensive,,, Only Pros or very wealthy enthusiasts would buy these,,,

Maybe the enlargement of the mount diameter can help design simpler high-performance lenses that would not be so expensive.

In any case it seems that Nikon have largely given up on the broader consumer market and want to target enthusiasts and professionals with their products. These might be expensive and Nikon do predict reduced sales volume but maybe the profitability is expected to be good. As the overall dedicated camera market dwindles, this might be a good strategy. Fewer units sold but with higher quality.

Thank you for your thoughts!


I must say I have never seen a fault as such in the VR system itself, only in the resulting images occasionally.


The VR in the latest 24-70 AFS f/2.8 is remarkable effective on the D810 gripped.


Less consumer, higher quality - Seems like a good strategy.

This recent essay on PL is quite a good summary of the stakes and possibilities:

Many lenses have rectangular masks to cut unwanted light, so probably a square sensor of equal diagonal would not be covered.

Though its highly likely we’ll get a regular FX sized sensor the technical limitations of older lenses doesn’t have to be an impediment for bigger sensor sizes. With the introduction of the first FX cameras Nikon provided the option to automatically crop the sensor when a DX lens was mounted or to ignore this for the lenses which worked (partly) well outside the DX area.

not seeing the F made me cry a bit

Thanks will

The line "A Gateway to a New Dimension" can of course be interpreted in multiple ways, incl a new sensor shape or size

Here's a quick screenshot of the new camera and mount.

Looking at the eyes for the straps the camera looks tiny 


Indeed, nice ref to a new dimension    he he

Tiny camera with a big mouth

The forthcoming native AF lenses for the new mount will most probably feature manual “focus by wire”. The reason could be simple: for mirrorless there is no requirement anymore that manual focussing is possible with the camera in off position (and thus no finder active), and focus by wire is simpler and cheaper than the DSLR AF-S design with the mechanical clutch between focus ring and focus lens group.

Hopefully Nikon will keep the seamless switch between manual and auto focus as is possible with the AF-S lenses; manual focus always active, and AF (single or continuous) can be initiated at any moment by pressing the AF-ON button.

I am not aware of any mirrorless that can it it exactly like this, Nikon can make all the difference here.

,,, the DSLR AF-S design with the mechanical clutch between focus ring and focus lens group.
,,,

Not sure what you mean by mechanical clutch ?

[Eddie Draaisma]

The mechanism that couples focus ring and focus lens group, and that can be overridden anytime by the AF motor. So a kind of “clutch”.

[Birna Rørslett]

I noticed the new mount still will use the space-saving lateral contact points camera-lens. Thus available space inside the camera bayonet is maximised, which should help designing fast lenses.

[Erik Lund]

There are several different designs of incorporating SWM into AFS Nikkor Lenses.


The SWM ring motor lenses don't have a mechanism that would be described as a clutch,,,

[Eddie Draaisma]

There is a uni-directional coupling between the focus ring and the focus lens group. Turn the focus ring and the focus lensgroup will move. But the other way around, move the focus lens group through the AF motor and the focus ring will NOT move.

This uni-directional coupling works in off mode, so it is “mechanical”. I call it a “clutch”, feel free to give it a better name...
