AUTO ISO Problem

[kennyloh]

Please excuse me if this post is reposted a few times but I cannot seem to get my posting posted. So I keep trying

 

Anyway, my A7R II is going off AUTO ISO and into ISO 50. I noticed this as my shutter speed will suddenly become extra slow while I am shooting.

 

Other settings I have made include setting the minimum shutter speed to either 1/125 or 1/250. I don't like the camera to set the shutter speeds for me.

 

I wonder if there is a bug which triggers this problem. I usually like to change FOCUS MODE and FOCUS AREA as I shoot. For some reason, some setting is triggering the camera to go off AUTO ISO.

 

Does anyone have this same problem? I am running the latest firmware.

Thanks you.

Any chance this is an issue with returning to a memory recall shooting mode?

You probably have ISO set to the wheel on the backside. Some people tend to knock that wheel while shooting. Try setting ISO to something else and the back wheel to NOT SET.

I second Yali's post, I had many a landscape shot degraded by unknowingly changing ISO from 100 to auto or 200. I leave the wheel to not set and put ISO where WB is on the wheel.

I'm glad I'm not the only one this happened to.

I watched as my Sony A7r2 switched settings from Auto ISO to ISO 50 without touching any dials.

This happened in both Manual and Aperture priority modes with different lenses.

It happens over multiple shoots, both inside and outside, with a range of metering modes, and aperture settings.

So the next person does not feel bad. It is definitely not a user error, I'm sending it in for repairs.

Just chiming in with a "same". I will try Yali's idea but I think it changes randomly and it's making me want to change cameras.
