Hi Kit and Kim,

Kit is right, this back can not provide real time previews, as the sensor is
not capable of it.  Only a sensor type called "interline" can do this.  The
other issues are the mirror, and the shutter...remember, this sensor
requires a mechanical shutter (Interline sensors do not, they are their own
shutter, and that is why they can provide real-time preview...they are the
types used in cheapo P&S digicams AND digital video camcorders), and the
mechanical shutter would have to open/close with some frequency to be able
to do this...and you'd have to be able to read out the data from the sensor
in "somewhat" real-time...

Austin
