a77 ii EVF behaviour - Pop up flash vs Speedilite
I primarily use my a77 ii with 70+300mm sigma + raynox dcr 250 as a macro setup. Till now I was using the pop up flash as a primary source to freeze subjects with very good results. Typical apertures around f18 with SS as 250 and pop up flash.
To get more flexibility, i tried to move to a dedicated flash Youngnuo 560 EX ii. I could see that flash was getting fired as expected even though it was probably a canon flash, all thatnks to the MI shoe. However, the problem i'm having is that Viewfinder is extremely dark at f18. I know you would be thinking that is expected behaviour, BUT when i used the popup flash the EVF was much brighter and helped me focus. With the dedicated speedilite my EVF stays dark.
Is this expected or some setting in a77ii. Please help!
