That means you assume that an EVF can be made to work at the speed of light. Fact is there will ALWAYS be lag. it is a matter of whether that lag can be reduced enough for serious wildlife photographers. Clearly you are not a serious wildlife photographer so you probably have little understanding of what that niche entails but trust me. Meeting the needs of wildlife photographers is not 'inevitable' for mirrorless. It is a serious challengeI'm not talking about a workaround with current products, I'm talking about future improved EVF products that meet your needs. Inevitable.
