Hi,

Let's use your approach and say that in the best case scenario EVF resolution catches up with OVF resolution. The issue will remain that EVFs exhibit lags where OVFs are instantaneous. It simply takes milliseconds of processing time to capture the image, process it, relay it and display it in the EVF. So for tasks like sports, birds in flight - anything that needs critical timing, the OVF is likely to be faster - probably always.

Not probably, 100% for sure.

OVF = the speed of light.

EVF = the speed of light + processing time.

Ergo, an OVF will ALWAYS be faster, period.

Your reaction, about 0.25 seconds, is much slower than both, so it does not matter - if you want to shoot action, you have to anticipate anyway, and the amount of anticipation varies by insignificant percentage (smaller percentage than the variability caused by different shutter release lags in different cameras).
