should be:
as we know that mechanical shutter is enoughly accurate for any photographic work,
if properly adjusted. Electronic shutter doesn't give a lot to photographer
working in manual mode. Also: when camera with electronic shutter shows
selected speed, it shows only a value it choosed. Please consider a led
shutter speed display - as in many older SLRs - you see '500' as
camera selected shutter speed. You decide to overexpose two stops and
turn exposure correction wheel until '125' is shown. Right?
WRONG! as in first case camera-selected shutter speed could be anything
from 1/375 to 1/750, in second case it could be anything between
1/90 and 1/180. So you corrected somewhere between 1 and 3 stops.. :)
Electronical shutter has some other drawbacks, depending of construction.
It frequently drains batteries on B setting. It is frequently a lot
more sensitive to dust than mechanical one, as electromagnets operate
in small distances from parts they hold and even small grain of sand
can stop them from functioning. More: electrolytic capacitors in electronic
cameras die very quickly or lose their capacitance.
