It may be.

But none of the scales are true for any intermediate focal lenghts.

Not necessarily. See my other post on how Leica solved the problem. Nikon's way sounds clunky in comparison...

I have just read your other post and I am not convinced of the merits of the system you describe.

I'd much rather have an unmarked ring and get the accurate aperture info in the viewfinder at all times.

I do not believe that the unmarked aperture ring is a sign of lack of commitment on Fuji's part to the X system.

I agree with you 100%. This inconsistency (along with the light leaks of the first X-T1 batch) is the main reason I am still sitting on the sidelines undecided whether to buy into the Fuji X system or not.

The memory of Panasonic 4/3 with their Leica lenses is still raw. Some years ago I bought into the system stupidly believing that Panasonic would continue with the lens line, only to see the aperture ring unceremoniously dumped and the lenses replaced by unremarkable plastic toys.

Changing systems is not cheap. Ask me how I know...

Now I am simply not convinced Fujifilm will not pull a similar trick in the future. Their current behaviour does not inspire confidence.

As for the variable aperture argument: it does not hold water. Leica 4/3 zooms had this sorted in a simple and elegant way: When the aperture on the ring is set anywhere from f/3.5 to 16, the same value is displayed in the LCD. If the value on the ring is set to f/2.8, the displayed value varies from 2.8 to 3.5, depending on the focal length chosen (at wide angle the displayed value matches the value on the ring, while at tele, the displayed value is changed to f/3.5). The discrepancy only occurs at the fully open end of the aperture scale. One click up from f/2.8 and there is no difference between the ring and the display.

What does hold water is simply the cost argument (and possibly testing of the water for customer response to possible future design simplification).

To Fujifilm (if they are reading this forum): You have chosen to own this market (along with Leica which is of little consequence to most of us) and you made many customers happy. Some display of commitment would probably go a long way to increasing your share of this market.

Ken re: "The discrepancy only occurs at the fully open end of the aperture scale."

Perhaps we just see the world slightly differently (which is ok by me), but IMHO a good solution is one that does not allow any discrepancies between the aperture-ring setting and the actual aperture.  So I can't agree with you that the above-described solution is "elegant" (assuming I've read your post correctly that is).

Fujifilm has heard the complaints. The next two zooms will have aperture rings.

In the meantime, either get new lenses, or find a system that suits your tastes.

Quite. Another system.

Leica? Anybody? You can get it in ostrich skin...

The new Nikon G lenses don't have aperture rings and I haven't seen anybody complaining about that. The older lenses had aperture rings, but they were pretty useless as you have to set it to auto position when using modern cameras, otherwise the camera would not operate. But even in the manual mode you have only two marks for the wide and the long end and have no idea what aperture is for anything in between. So it was all useless and Nikon got rid of the aperture ring altogether.

It may be possible that you haven't used a Nikon digital camera before. It may be possible that you have but got lost in the maze of menus. I have. I only use Ai/S lenses for my Nikon cameras and every one works perfectly. AFD lenses, too, work jsut fine, in both A or manual aperture. You merely have to set the camera to ignore the camera-side aperture dial and use the ring. If the lens itself doesn't have any electronic connection, you just mount it and fire away.

Some cheaper Nikon cameras lack metering capabilities, but most work the exact same way as the Fujifilms do: focus wide open, meter set on the aperture dial, and close down for exposure. The difference of course is that they are coupled and mechanical. You can free lens stopped down or wide open, use the lenses on tubes and extension rings, and do heaps of stuff to your heart's content.

The aperture ring does allow more spots for ingress of water and other foreign elements. That is probably the number one reason Nikon dropped the aperture ring. Well, that and people probably were not using rings much with the dials on the bodies. Also, real mechanical aperture rings cost a bit of money and have to be very accurate. The electronic uncoupled system Fujifilm uses saves weight and is much much less expensive to produce than the Nikon system.

I find it very annoying.  One of the attractions of the Fuji X for me is stepping away from menus and displays to direct, mechanical controls.   That they don't mark lenses like the 10-24 tells me there are people at Fuji who just don't get it.  Why else make the XT1 with three big, marked dials on top?  The point is you can look down at the camera, even when it is off, and know your settings.  The point of THAT is so you can have the camera ready to go in a new lighting situation or just after changing lenses, without having to turn it on and look at the freaking screen, or worse, hold it up to your eye to look in the EVF, just to turn it off until you're ready to shoot.

Shooting styles differ.  I like for the exposure to at least be close when I power up and start snapping away.

Hopefully they find the plot before losing their tenuous hold on this admittedly niche market.
