Have a definite bug to report that a firmware update will hopefully address. Just started a post in DPReview to see if others are having this issue. I apologize for the lengthy description.
“Setting effect on” PROBLEM:
Having an issue with my A7R3 and live view. In Live View (setting effect IS enabled) when I’m shooting AE. I can dial in exp. comp. and get a very good representation of how the exposure looks, especially when using on-camera fill flash. I know fully well I won’t get a live view representation of my flash exposure, just ambient.
Scenario...
Setting effect is enabled in the menu. At a set aperture/shutter speed the monitor or EVF gives me a close approximation of how the image would look. Thats how it IS supposed to function. IF I mount and turn on ANY hot shoe TTL speed light (I’m using Flashpoint) the Setting effect function automatically DISABLES. That’s NOT how it’s supposed to function. When I’m doing on-camera-speedlight shooting, where the flash is set to fill my ambient, I want a live view (Setting effect enabled). Why is the camera disabling the Setting effect in this scenario without me touching the menus?
UPDATE I tested, IF I turn on a mounted speedlight, the setting effect in either the EVF or monitor disables BUT, even when disabled the Live View Display STILL says "setting effect on", but it IS off. This “has to be a bug in the A7r3”.
On my A6500, under the same circumstances, the 6500 works as intended. IF Setting effect IS enabled, it stays enabled regardless of using or not using a mounted speed light.
