ISO change to reflect live in EVF?

I recently purchased the XT-10. I am working on my manual mode skills and have a question. I have my light meter in my EVF, but when I need to change the ISO to reach proper exposure I have to press and use the front dial which takes me to another internal screen. This leaves me having to guess how high I need to go with my ISO to hit the proper exposure. Right now I just guess then check back to my normal EVF view and then have to make an adjustment again if I guessed wrong. Is there a way for me to change my ISO and have it show me live in the EVF light meter like it does for aperture and shutter speed changes? Thanks, Kim

Your EVF light meter tells you how many stops you are off the mark. Just change the ISO setting accordingly. F.ex. if the meter says you are about to underexpose 1 2/3 stops, adjust the ISO setting up f.ex. from 800 to 2500 or from 400 to 1250. No need for guessing or switching back and forth to check if you have set it right.

 

And yes, ISO can be assigned to a function button. You can also assign it to any of the positions on the Q menu. I use both. I like the Q menu to show me the settings I find most important, including ISO. So I can see and change the ISO setting via the Q menu.

However In my opinion there's a distinct advantage to assigning ISO to the front wheel and changing ISO by turning the wheel. Pressing the wheel enables you to choose the ISO value by turning the wheel, but it also enables you to change the settings for the three automatic ISO modes, something you cannot do from the Q menu. I use this to quickly change the maximum ISO value in automatic mode.

 

I've had my X-T10 for a month and an X-M1 for almost two years. Although in many ways similar (notably the sensor and the lenses of course) the X-T10 is a much more manually oriented camera, which makes it much more fun and powerfull to shoot with.

One possible alternative is to set ISO to Auto mode. It will automatically tweak ISO value in Manual mode to required value that fits measured exposure and your Exposure Compensation value set. On half-press it will show you real ISO value that is going to be used for the shot.

If required ISO value exceeds possible range - you'll see that on Exposure Scale - indicator will be lower\higher than desired value.

I guess you just mean you can't see the exposure indicator in the viewfinder. But the point is, you can still see the scene in the viewfinder, and know in your mind what the trade-offs are for the different ISO levels - and that is really how to gauge your exposure in manual. The meter reading is just what your camera thinks might work, but your eye and brain should be the real judge anyway - unless you're actually looking at a gray card. But if you want your ISO to just be set to the exposure that your camera thinks is right, rather than what your own brain tells you, then you don't need to use manual, and should leave it on Auto ISO.

 

Another point to bear in mind is that you can see on your exposure meter how many stops you are away from the camera's idea of correct exposure before you launch the ISO menu. So if you check that first then you already know how many stops you need to move the ISO, and don't have to guess and check back.

      Does the Xs 10 have the Dual Iso at 640 and 2000? I can't see the difference in noise reduction when it comes to 2000 and Im wondering is it a defect of the camera or is there a setting that I've to turn on. That's if the Xs 10 even supports it in the first place. I'll be thankfull for any feedback because I've been racking my brains trying to work it out. Thanks

      Hi guys,
      Before I'm taking my XT3 for repair, making one last check:
      My ISO dial apparently stopped working - the ISO level is on 320 and turning the dial just won't do anything anymore.
      Also, tried to set the command dial to change the ISO with no luck, and I'm pretty sure I've adjusted everything correctly in the menu.
      The only time the ISO DO change is when I put the camera in F-LOG, then it changes to 640.
      Any ideas? I'm pretty lost here.

      What real-time exposure display options are available with manual lenses?  I am investigating Fuji, with an X-T1 and a manual lens (no contacts).  I want to see what ISO and SS my camera has chosen, with the current lens settings.  (I would also like to use program shift to change the ISO/SS combination up or down.)  There may just be some setting somewhere that I didn't think applied to this?  I have turned on all the display options and have tried the different displays, but no ISO or SS displayed unless I manually set them, or if I depress the shutter [but that's not real-time, as I change the aperture ring].  I have the newest firmware, and I have reset my camera's settings several times, so almost all my settings should be at the defaults.

      I am very used to Olympus OM-D E-M1.  On my OM-D camera, as I reduce the aperture on the lens, I see my ISO 200 / SS 1/30 move, maybe to 200 & 1/15.  Then if I move it further, maybe this time it changes the ISO to 400 and keeps the SS at 1/15... but I see it all change as I move the aperture.  If there's no clicks then I see it make minute even fractional changes to ISO & SS.  Program shift via the front dial will also change the ISO/SS up and down.

      Hello everyone, pardon me if this is a newbie question but in my fuji X-T3, the minimum ISO for movie/video mode is 1000 and it seems that I can't turn it lower than that. Does the camera detect the ambient lighting and keep the value to 1000 or is it because of the lens that I'm using? (which is fuji xf 18-55mm f2.8-4 by the way) or maybe there is a way that I can change that in my settings? Thank you in advance for your feedback.

      Hi,
      I tried to adjust the command rear dial for ISO, but was not successful.
      I went through the correct procedure: Wrench, Button dial settings: command dial settings: back dial setting: ISO.
      I was able to change it for exposure compensation but not not for ISO.
      Any help would be appreciated.
      Thanks,
      Steve
