Question about TAv + Auto ISO

Postby aremesal » Mon Sep 12, 2016 11:45 pm

Hi!

I've just bought a GR, and have spent some hours navigating the menus and configuring the camera to my preferences. I've it almost done... but I've an issue with TAv mode and the Auto ISO.

I set up the Auto High ISO limited to 4000 and 1/125. I select the TAv mode so the camera chooses the ISO... and then the camera has no limit with the ISO, resulting in some photos at 25.600 ISO. I can't find any other config item about Auto ISO apart from the limit to 4000-1/125.

Is it possible to limit the max ISO when in TAv mode?

My camera firmware is 4.0

Thank you so much, Rene! That is exactly what I needed! ;)

That post confirmed me that Auto ISO in TAv has no limits... and the trick to limit it using the DR is great!

I'm going to do some tests about the consequences of the DR setting both in JPG and RAW.

Thanks for the tip!
