EOS 5D Mark IV Auto ISO keeps ISO too low

[Aurel8]

Hello,

I'm having a very annoying problem with the auto ISO behavior of my 5D Mark IV : it is very reluctant to climb in ISO and tends to stay in rather low settings while compromising the speed, and even setting a slower speed than the minimum speed that I set (1/125). For instance, when it should go to ISO 800 and 1/250, the camera choses ISO 200 and 1/80 (The max ISO value in ISO AUTO is set to 3200)

Anybody ever had this problem ?

Hi, 

I finally checked my camera and the safety shift was turned off ! So it's strange that the minimum speed is sometimes being overriden
