another: the sensor is more sensitive to begin with.  Amusing
theory given that they use the same sensor.  The a57 just gives
up 1/3 to 1/2 stop due to their puzzling use a old technology
called a Translucent Mirror.  It is possible to have an EVF
without this loss (such as Olympus and Panasonic do).  I don't
understand what advantage Sony thinks they get with this
approach.  The viewfinder in the gh2, for example, compares
favorably to the Sony ones I have seen.  End of day, the end
results aren't much apart. Much less than you suggest based on
your belief that it must be bad because "light is taken away".
But it won't matter what anyone says. Beliefs isn't something
that anyone can influence.  Again you are just wishing for stuff
without checking out the facts. Th
