I hear and understand that people like it, but I never got why managing ISO manually was such an issue, especially with the Q menu.

After aperture priority and half automatic modes became standard (long long ago), flexible Auto-ISO is the last step to get rid of the film heritage. With film you are bound to one sensitivity till the film roll was full. In digital photography you are not. You can change from frame to frame, according to the circumstances.

When light is even and constand (and bright), one doesn't really need Auto ISO. However when walking or trekking, or shooting street, light situations can change continually (like walking from sun to shade and back again). It can also happen that you have not much time for every shot, and have to react quickly. This will result in pictures that have low ISO (= high quality), but too long shutter time, because you didn't have enough time to change ISO quickly, or pictures in bright light made with ISO800 or higher, and unnecessarily short shutter times, for the same reason.

Only programmable auto ISO makes sure that for every shot the camera selects the lowest possible ISO (without risking camera shake or motion blur, according to your pre-set manimum shutter time), and that you can simply forget about ISO. In the other case you have to think constantly of setting and resetting ISO to adapt.

It is an easy fix, just a few lines of code, and Fuji should add it quickly. Where is the best Fuji adress to write this complaint to?

That's why there's an aperture control, and AE. Again, I understand why people use it, but I've just never encountered a situation where I didn't have time to open up/stop down the lens, and where both aperture and shutter speed where critical. I've got Aperture/Shutter priority AE (all it does is adjust ISO) on my Pentax DSLRs, which I believe is pretty much what people are asking Fuji for, and I never use it.

It has nothing to do with film heritage (ISO in the film world is an entirely different concept, since you had to make the choice pretty much before you left the house for the day, and live with it) and everything to do with managing your exposure. I just don't see the need to constantly tweak the ISO to get it as low as possible. Noise is basically non-existent with the X-series below ISO 800, and at ISO 800 in daylight or open shade I can drop the shutter speed anywhere i want it with aperture. It would drive me nuts to have every image from the day at different sensitivities. Simple way to makes sure the camera selects the lowest possible ISO - select the lowest possible ISO. Simple way to avoid camera shake? Open up the lens.  No guessing  no software, no surprises when the you take the 'I have to take it now!' shot, and the camera does something wacky. No thank you.

But to each their own.  I personally think the ability to turn off auto-gain in the EVF in manual is a much higher priority, and no one but me seems to care about that.
