If they curve the sensor, all the other lenses out there that people might have adapted will be useless. One of the major points about mirrorless is the ability to mount other mfg and types of lenses. There may be benefits to this, lens size, weight, but it's also a sneaky way for them to make sure you only buy Nikon glass.

I think a curved sensor may work *better* with vintage lenses. I recall
that one of the advantages of the Olympus lenses for digital cameras was
their optical modification to project directly to the edges of the
sensor, whereas the edges received angled projections from vintage
lenses, reducing the amount of light the sensor received.

If so, then vintage lenses have less of a disadvantage when projecting
onto a curved sensor. Even so, why would this be relevant only to
mirrorless cameras?

their *ads* made that claim, and as with most ads, it's misleading.

the exit pupil of most lenses (including vintage) is far enough forward
that it has very little effect on the edges of a sensor, regardless of
manufacturer, particularly with slr lenses (to clear the mirror box).

Well, you could optimize the angle to its center, considering that most
lenses are retrofocus these ddays. The big thing though would be to
take advantage of the shorter flens distance and put the theoretical
nodal point closer to the sensor giving a better angle towards the
sensor for incoming photons.

that's the point. most lenses already are.

olympus was bragging about doing something everyone else had already
been doing.

take advantage of the shorter flens distance and put the theoretical
nodal point closer to the sensor giving a better angle towards the
sensor for incoming photons.


that is a *higher* angle of incidence on the sensor, the *opposite* of
what olympus was claiming.

on the other hand, it's trivially remedied in post-processing.

I had one of those Evolts by Olympus. The claimed that their lenses was
better adapted to the deph of the photon wells beter than legacy ones.
With those that I got in the box it was hard to tell...

He seem to be an experinced man with a wast knowledge in the field of
photogragraphy giving the masses that that they want!

his experience is in fooling people into clicking his links.

most of what he says is factually wrong, which he readily admits.

You mean like the old 70-200 on a FF camera?

The thing is since that's a retrofocus design, almost all modern lenses
are you could make it more compact and have more design options if the
distance between the mount and sensor were shorter.
