In may case with the Samyang, the aperture would be missing as well.
Shutter speed is there, since it's done by the body - as is the ISO.
But since the body doesn't know the aperture, as it's in the lens, it
can't calculate the EV. Would this be a consistent constellation for
manual lenses, then - EV 0 and no aperture? Then if they occur
together, maybe one could safely assume a manual lens.
