Nikon is trying to make a virtue out of what is really their Achilles
heel - a hodge-podge of lenses and bodies that have limitations. Some
bodies don't focus with some lenses; some bodies don't meter with some
lenses, some lenses jam if they are mated to some bodies without mods to
the mount.

They're trying to score off Canon, who bit the bullet and designed a
proper modern mount, able to accommodate larger rear elements, and
provide full operation - focus, metering, aperture - with every EOS EF
lens made, and several EF-S lenses for cropped-sensor cameras, in
addition to those cameras accepting all EF lenses as well.

There are the diehards who claim that Canon abandoned their FD mount,
rendering FD lenses nearly worthless. It did not stop those who
continued to use their FD cameras, only those who migrated to the new
EOS system cameras, and it was all 25 YEARS ago, a quarter century!
There are many pro photogs using EOS cameras today who weren't born when
the change was made.

Nikon is flogging a dead horse here.

Aaahh, Floyd, how many people buy a pro Nikon versus those who buy the
entry grades?. The entry models, and some pro-sumer versions do suffer
from the limitations I outlined above. For those, lenses can be a
problem. You suggest the way out is to buy a D700 or D3x with a
(mostly) unused focus motor in the body, at multi-thousand dollar
prices? For amateurs and hobbyists?

Every Canon EOS camera made, from the humble 300D right up to the latest
5DII and the 1D variants can fully use all EF lenses, no limitation.
That advantage alone is worth the mount change.

Nikon painted themselves into a corner by not grasping the nettle and
updating their mount, thereby dooming their system to kludges and lost
capability with many body/lens combinations, not to mention future lens
design.

Canon foresaw the huge advantages possible with the application of
electronics to camera functions, even before digital cameras were
envisaged, and bit the bullet by changing the mount right at the start,
setting their cameras and lenses up for unfettered future development.

Whatever one may think of the actual cameras from both stables, the
Canon mount change was far-sighted indeed. In modern speak, the death
of the FD mount and its lenses could be called 'collateral damage',
justified by the advantages of the EOS mount - which, by the way, still
has much room for future development, squeezing the Nikon mount design
even further.

As I said, Nikon are trying to make a virtue out of a design mistake
made 25 years ago. Their new cameras are like a modern car, all mod
cons, power steering, active suspension, the works - and powering the
vehicle with a 1950's carburetted Ford flathead V8.

All I know is that my old 200 micro, ai converted 24 f2.8 and 50 1.4 work
as well as they did on my Nikkormat and F3. I will not go further in you
holy war.

It's interesting to actually look at three of the pre AF lens mounts.
Nikon F mount: simple bayonet mount with a locking pin and release
button on the camera body.
Canon FD: with it's reverse bayonet (male body, female lens), the
locking mechanism is a turning ring on the breach end of the lens.
Pentax K: Essentially the same as Nikon: just a slightly different
design with the "teeth" on the bayonet and position of the locking pin.
Olympus OM: Similar again to Nikon and Pentax, except that the locking
pin and release button are built into the breach end of the lens.
Nikon F, Pentax K, Olympus OM all have a flat mating ring surface all
around the actual bayonet.

To make an AF mount out of Nikon F, Pentax K, Olympus OM all that was
required was to add a screw drive pin to the lens mount on the mating
ring surface and that's about it.
The body can control the aperture in exactly the same way as the manual
focus cameras.
Canon FD has no mating ring surface around the bayonet, so there's
nowhere to put a screw drive pin and so it is apparent that their
designers were forced to start again.
Thus EF mount was created.
