No it does not affect actual exposure as the mirror blocks that light path when
it is in the up position. Now some old cameras with deteriated foam may have a
problem, but there should not be one with any SLR in good condition*.
* Ahem! Except maybe for those with pellix mirrors.

under exposure is not acceptable, of course. However, when using the MZ-S, I
don't need to cover the eyepiece. I can just activate the HOLD button, to

I assume that HOLD does the same as exposure lock in the -5n, which is
the same as metering and setting to Manual mode. I thought the problem
is not just to do with the metering, but with the exposure itself too.
Otherwise, what's the point of the eyepiece covers?
Curious,
