X-T2: proper live preview exposure WITHOUT lens set to manual

For the X-T2:

Is there a way to get proper live preview exposure WITHOUT the lens set to manual?

Yes, but I find this whole post a bit confusing.

If it's set to "A", the image is always bright (nice preview for composition) and the image automatically brightens in a dark room.

You don't specify how SS and ISO are set but yes the camera adjusts the aperture and other settings if it can to get proper exposure.

If it's set to "*" (the aperture image setting),

Not sure what "*" is, do you mean an actual aperture like f4 ?

Member said:

the image goes dark as it should with the selected settings.

If you are in full manual ie no auto anything then yes if you stop the lens down it will get dark

But the lens no longer automatically adjusts.

If it is not set to "A" as you seem to state above, then there is no auto adjust for aperture, not sure why you think there would be.

Why this behavior? It seems counterintuitive to me, could someone explain?

Hopefully my comments above clarify things otherwise I am confused as to what behavior you would find intuitive.

Thanks. I'll clarify one of the points you asked about, perhaps that will motivate the question more clearly.

- I set the lens mode to "A"

- The lens is wide open(eg f/3.5 for the 18-135).

- Shutter and ISO dials are set manually (to some fixed non-A value)

Using these settings, the image is artificially brightened on a half shutter press. Clearly the aperture can't open further than its max, so it's electronic amplification just for the screen readout.

Thus what I see in the viewfinder is deceptive, and NOT the image that the camera takes. In a dark room the screen may look bright, but the captured image will be near-black.

But if I set the lens mode to the non-A manual mode -- I called this a *, and as mentioned that marking looks like a set of aperture blades -- then the camera DOES preview correctly, but the aperture will no longer adjust automatically.

To me, ideal behavior would be showing the actual preview exposure, regardless of which mode the lens is in. Or being able to switch it to amplify for all lens modes.

I don't know why this preview should be mode-dependent, it doesn't make sense to me.

I normally shoot full manual mode, so I don't routinely see this issue. I tried doing exactly what you described and I see your point. I agree with you that I think that the camera shouldn't boost the EVF image brightness when the F stop limit is hit. On the other hand, I can see that people might be confused by a near black screen as well and that's why Fuji chose this behavior. You should notice that the f stop number in the viewfinder turns from white to orange when the f stop capability of the lens has been exceeded. This should be your indicator that you need to change the ISO or SS to get back into proper exposure range.

Are you in AF-S mode by any chance?

In the menu screen setup below the "View exp/WB in manual mode" there is "Preview Pic effect". Is that any help?

I do have it already set to Preview Pic Effect in both exposure and WB
