Re: HELP - Firmware 1.11 for *ist D

[Peter J. Alling]

You are splitting the light sending some to the viewfinder and some to 
the sensor, you lose between 1/3 to a full
stop in exposure, and have a rather dim viewfinder.  (I'm not sure about 
what effect light leaking through the viewfinder
might have on the exposure as well but it probably isn't good).

of the E-10 to be very nice, and have always wondered why it isn't done
more, especially since it eliminates mirror slap.  Is it just too
expensive?

The E-10, E-20 and E-100RS cameras employ a prism to split the light
between 
the finder optics and the sensor and they also use a sensor which does
not 
require a physical shutter as does the *ist D and its contemporaries.
