i just restore to 8.33 and install asi 2.1.10.74 again, it's work with A7C, i can select ISO setting and take photo without problem.. then... after i installed 2.1.2_0202 again, it doesnt work anymore, same as what i mentioned before, no more ISO setting,
one more bug i just found out, using 2.1.10.74 with A7R/A7S either A7C, selecting ISO setting is very smoothing change, just like ISO800 -> ISO3200, can immediately change to the what ISO setting i selected, 2.1.2.0202 with A7R or A7S, changing ISO setting will lag behind, like ISO800 -> ISO3200, can see the camera screen ISO800->ISO1000->ISO1250->ISO1600->ISO2000->ISO2500->ISO3200 one by one.. about 1/2s for each ISO .. so the whole setting change likey about need 3-4s to change...it's abnormal...
