Are there any Nikon lenses that DON'T use mechanical aperture coupling?

When you mount a Canon lens to a Canon body, there's no mechanical connection between the body and the lens. Control of the lens (i.e.closing the aperture as well as focusing) is completely electronic.

It seems that Nikon has been dragging its feet in this department, and lags behind Canon. While Nikon lenses produced nowadays have their own autofocus motors (and no longer use the focusing motor / shaft in the camera body), they STILL require mechanical control of the aperture (i.e. The aperture lever in the camera body manipulating the aperture lever in the lens).

I find it absurd that Nikon hasn't gotten rid of this immediately. What I'm wondering is: does Nikon even make lenses whose control is purely electronic, like Canon's?

"It seems that Nikon has been dragging its feet in this department, and lags behind Canon."

Why? Canon paid a high price for that completely electronic control system of their lenses, namely the loss of compatibility of the older FD mount lenses. I guess when that happened in 1987 they really infuriated lots of photographers.

In case of the autofocus control there's a good case for controlling it electronically (albeit the old AF lenses that Nikon makes still work perfectly, and Pentax' ancient screw AF system gives both Nikon's and Canon's electronic systems a beating in my opinion, at least in terms of speed)

In case of aperture control there's basically no benefit whatsoever in doing it electronically.
By keeping it mechanically Nikon maintains backwards compatibility to legacy lenses, which is much appreciated by many photographers.

So… No, as far as i know there are no electronically controlled apertures in Nikon lenses. If i recall correctly even the top of the line Nikkor 24-70/2.8 uses the lever.

It's Nikon's proud boast that ANY Nikon lens will fit ANY Nikon body. Pentax use the same philosophy.

Since they started in 1959, before TTL metering or automatic indexing, let alone autofocus, this is no mean feat.

When autofocus came in, Canon (like Minolta) threw away decades of experience by completely revising their lens mount - so much so that every lens and body they'd made up to that time became obsolete overnight. Things worked out eventually, but slapping your customers in the face like this doesn't strike me as a good way to do business.

I'm willing to go along with you and say Nikon was late when it came to motorizing the focus system. But aperture… I really do fail to see the disadvantage of that.

Even as a dedicated Canon fan I can't see how you can denegrate Nikon over this.

Ultimately the operation of the aperture blades is mechanical - at some point an electronic command is converted into a mechanical action to move the blades (or adjust the focus)

The only difference is the location of the electro-mechanical interface - inside the body (Nikon) or inside the lens (Canon).

If it ain't bust, don't fix it - Nikon lenses are top grade!

They have, however, created something of a dog's dinner with their "shall we, shan't we" on the location of the electro-mechanical interface for focusing!

Nikon has done very well to maintain so much compatibility between lenses and cameras which may have production dates 50 years apart.
The CEO and technical staff of Nikon won't be too happy with your denigration of their approach.
If you don't like Nikon there are plenty of other choices.
My old Nikkormats and FM still do sterling service and the lenses can be used on a D90.
Same lenses for film and digital. Pretty good going.
