I know most of you think the EVF doesn't lag in low light. And for the most part I agree, the EVFD gets more noisy but the refresh rate still high. But I shoot with a flash in low light, so I turn my exposure preview off. So try this on your XT1s and see if you get the same lag I get, set the lens to f8, go somewhere relatively low light, and then half press the shutter... Can you see the lag? The only way for me to get rid of the lag is just to mash the shutter and not do the half press. I don't like shooting like this because it feels like I get a slight shutter lag, compared to half pressing the shutter and waiting for the right moment (I use AFC with AF button set to AF and the shutter release set to exposure metering).
