ILCE-1 (A1) ISO Control wheel issues

[Mikey.B]

Is anyone having similar issues to this?  Shooting some Astro landscapes last night, I noted that my ISO value flicked straight from 600 to 3200 without showing the intermediate values as I turned the ISO control wheel.  I repeated the task several times, turning the camera on and off a couple of times to no effect.  I was shooting in full Manual, AF-S (tried AF-C same results).  The lens being used was  FE 12-24 G Master at F2.8 at various vocal lengths set to manual focus.

Have you checked the wheel functionality on other menu sections? Just to focus on an hardware or setting (software) issue

Hey, can you check the ISO sensitivity mode, is it set to Auto or ISO 50 – ISO 102400 here, if you have it set to Auto, and you are shooting in P (Program Auto) or A (Aperture Priority) can you check if you have the shutter speed adjusted to at which the ISO sensitivity starts changing here. Does it happen with different lenses also or does it only happen with this lens? I hope this helps.
